GIVING OLD TOYS A NEW LIFE

28.04.2023

Ivan Kocić graduated from the Faculty of Applied Arts in Belgrade, and for years he has been exploring the nuances of his artistic expression in numerous painting techniques and styles. However, today he is best known for his assemblages in which he illustrates female portraits using colorful plastic toys.

“I got the idea seven years ago while working on a larger classic mosaic. I thought it would be interesting to play with a mosaic using different materials instead of the usual stone, glass paste or ceramic. So, the choice fell on used toys that were brightly colored, which made the work easier, and of different shapes and sizes, which at the same time made it difficult to create portraits,” says Kocić and adds that from the beginning, his idea was to emphasize recycling in order to give his work a special social note.

“Today, after several years of work on the series I called ‘Recycling of play‘, it is obvious that the audience has accepted these ideas. Even the audience has become a part of this artistic action, considering that among them, I have a strong base of those who are happy to collect and donate old toys,” explains the artist.

Until now, Ivan has exhibited several times in Belgrade, as well as throughout Serbia and the region. Some works have traveled to distant gallery destinations, even to Mexico. The audience’s reactions are very positive, and the portraits leave no one indifferent.

“I think my works even inspire people to express their artistic ideas through some forms of recycling. That is one of the ideas woven into my works,” explains Kocić.

The youngest are the most active audience

Our interlocutor actively runs workshops for children that give the youngest a unique opportunity to transform their old toys into something new. Kocić explains that children are the most active audience; they are honest and straightforward in their question but also in their reactions to Ivan’s work.

“Little ones like to touch, to get close. After a short initial shyness, they relax easily because the toys are familiar and close to them as objects. In this way, they become interested and learn about recycling and contemporary art, represented by the portraits. From time to time, in addition to exhibiting works, I also organize workshops where everyone is welcome – from age 7 to age 77. Then, on a practical example, you can see the creation of an assemblage,” Kocić points out.

When it comes to collecting art materials, all old toys are acceptable. Ivan gets them exclusively through donations from children and parents, so they become collaborators in creating works of art.

“Most toys have a part missing. The consequences of their use, such as scratches and deformations, are visible. Quite often, I get new, unwrapped toys, and I give them to some less fortunate children who don’t have so many toys. In any case, the idea is to make assemblages from used objects, so I follow that idea,” adds our interlocutor.

Heavy Industry’s Transition to Clean Energy

28.04.2023

With governmental pressure in most countries ramping up and bold deadlines to phase out fossil fuel within the upcoming decades, many companies and industries are adapting to the large-scale transition to clean energy. For traditional heavy industries such as manufacturing and logistics, the shift is a big one, and identifying how to achieve that objective can seem like a very complex challenge. Here, Christian Carraro, General Manager South Europe at SolarEdge Technologies, a global leader in smart energy technology, shares his insights on the key issues that manufacturing and logistics companies need to consider to achieve their sustainability goals, and the business opportunities they can bring.

In Europe, there are some 300 industries – many of them international – that have set due-dates to significantly reduce carbon emissions. The years commonly range from 2025 to 2035, and for some, 2050, depending on the country. Promises have been made by companies to shareholders and communities, and pledges posted on websites. While genuine commitment to ‘play their part’ is a key factor, action is also spurred by incentives from regional utilities to encourage adoption of renewable energy – as well as the incoming carbon taxes on industries that do not meet legislated emissions levels.

Among the companies leading the cause are the heavy industries historically perceived as major polluters, such as oil and gas, chemical and automotive, logistics and large-scale industrial manufacturing. I have been working closely with companies in these industries for over a decade, helping them to transition to renewable energy, specifically solar. These operators typically have large premises and potentially acres of empty roof space, and solar modules provides a very visible demonstration of their commitment to sustainability. At the same time, the flexible nature of solar means it does not typically require planning permission, and, thanks to improvements in solar technology and fluctuating energy prices, the ROI period for solar projects is becoming ever more attractive.

For organisations whose business has never been power generation, making the transition to solar can present a challenge, and certainly there are several considerations that need to be taken into account. For example, there may be variations in national or even regional regulations that dictate the maximum size allowed for a PV system. Sometimes, the buildings used by companies may not have suitable rooftops, or the buildings may only be leased or rented making the landlord’s commitment to installations problematic. Landlords are often reluctant to allow a solar installation with a return on investment (ROI) of less than the occupier’s lease.

Within large industrial corporations there can also often be complexity in the decision-making process. This may involve corporate-level management, investors, regional management, plant managers, risk assessment officers, energy managers, sustainability managers, insurance officers, local officials (including fire departments), and often risk, insurance and energy consultants. The challenge here is to ensure all stakeholders in the decision-making process understand what the end-goal is and that they can work together to achieve it.

Addressing concerns before taking the road to transition

Once a company is aligned internally, the next step is to find competent partners who can help it navigate the transition and minimise risk. These are likely to include a mix of companies, from consultants and EPCs to technology providers who can provide expertise based on decades of installing solar systems. These providers could be either local or global depending on the needs of the company, though many companies that have made the transition often find that the involvement of local partners who know the regulatory and operational conditions is very important.

In a recent meeting with a large chemical company, I was asked in jest, ‘if our tree has always been fruitful, why take it down and grow a new one?!’. Referencing their long standing use of traditional energy supply, they knew the answer to the analogy, but it does exemplify a wider industry consensus that while the transition to solar is needed, it comes with a lack of understanding of its value and how to best implement it.

The transition to solar requires a solid understanding of the requirements and risk factors involved. First, the financial case needs to be considered. Solar provides a very attractive ROI over the total lifetime of a system, having saved many of our longsta nding customers millions. However, companies will have to bear the majority of the cost up front as CAPEX. The next step is the process of putting solar panels on the roof of buildings and achieving the promised energy supply, which is a relatively simple and low risk exercise.

Safety and Risk Management

With chemical, oil and gas, and automotive companies, the main concerns are around safety and risk. These concerns come from a variety of sources, from risk and safety officers, to building managers (and owners), local councils and fire departments, and the companies’ insurance managers. The insurance element is, itself, complex as it includes building insurance, insurance of the solar system, business insurance and general liability.

As the solar industry matures and the number of installations increase, stricter safety standards and regulations are now commonplace. These safety standards often outline that should maintenance on the roof be necessary, or in case of an emergency, the solar inverter must be able to reduce the DC current produced by solar panels to a touch-safe voltage within a specified amount of time.

Overcoming fear of risk takes time and requires the right experts to provide credible data-backed input and proper due diligence. We work with Marsh LLC, who are global experts in risk management and insurance-focused brokerage. Our partnership with such a highly-respected company with a long track record provides a lot of reassurance for enterprises that are considering investing in solar.

Cross-industry collaboration is key

Once the first PV installation has been successfully completed, we find that companies quickly move on to the next one, often accompanied by the question ‘why didn’t we do this sooner?!’. The completion of each successful solar project becomes the model for the next, albeit local adjustments may need to be made. For example, in some countries excess solar energy cannot be fed into the grid. However, we can help implement energy storage systems so that excess energy can be managed and used to further reduce the dependency on the grid.

It’s important to recognize that every industry has its own unique set of challenges which must be taken also be taken into account to ensure a smooth transition away from fossil fuels. One of the ways we do this is to bring together different companies from within the same industry, for example chemicals, to discuss their requirements and concerns. This helps us to better understand the specific needs of each industry and best guide them on what steps are required to effectively make the transition. You’d be surprised at the level of cooperation these often-competing companies can achieve in order to find the best sustainable energy solution to power their business.

Transitioning to a brighter future

While COP27 certainly shone a spotlight on the need to accelerate change, the reality is that the dial is slower than most of us would like. For heavy industries, the introduction of solar energy requires a shift in mindset on many levels. For example, it requires greater collaboration between separate departments and responsibilities. It also requires stakeholders to move away from thinking about risk reduction centred around initial CAPEX, to recognizing the opportunities to future-proof businesses, especially against the recent energy pricing volatility we’ve seen in many countries. I’ve spoken to many companies who now view solar as a valuable asset that not only helps meet corporate sustainability goals, but can also be turned into a revenue stream. When that suddenly clicks and the mindset changes, it really is a magical thing to see.

SYSTEMIC SOLUTIONS FOR A HEALTHY ENVIRONMENT

27.04.2023

The large amounts of waste we create affect the emergence and expansion of landfills, which leaves a strong negative impact on the environment. Landfills occupy large areas of land, rubbish is deposited in such places for years, and its composition consists of all types of waste, from municipal and medical to hazardous waste.

Currently, in addition to sporadic recycling places, which number is insufficient, almost all hazardous waste ends up in landfills and illegal dumps, where it decomposes, releasing huge amounts of harmful chemical substances that penetrate the Earth’s crust. We talked about waste management, recycling and ways to overcome numerous problems in this area with Tamara Spasenović, regulatory reform associate at NALED.

EP: What can you tell us about the Increasing the Recycling Rate for Batteries and Light Bulbs project?

Tamara Spasenović: We launched this project to shed light on the problem of these waste streams, while pointing out the shortcomings of the existing legal regulations and, through piloting the system, showing that a separate collection of waste batteries and light bulbs is possible. For this reason, and in addition to the comprehensive analysis of the situation that we carried out and recommendations for improving the legislative framework, we successfully established cooperation with the line institutions in Belgrade and Kragujevac.

The project officially lasts until December of this year. For the next period, along with the continuous collection of batteries and light bulbs, the plan is to carry out an analysis of the collected quantities so that, based on the data, we gain additional recommendations for further solving the issue of hazardous waste flows.

Also, an important aspect of the project is educating both school-age children and adults.

IN FOCUS:

EP: How are used batteries and light bulbs managed in our country?

Tamara Spasenović: Currently, our country doesn’t have an adequate systemic solution for collecting, disposing and recycling of batteries. Only one company operating in the Republic of Serbia collects and stores batteries and then exports them to Germany for treatment. The main reason for the non-existence of a collection network for this waste stream is the lack of state incentives, which would motivate the largest generators of hazardous waste to hand over used batteries to the system operator. With the support of incentives, they can dispose of those quantities and treat them adequately.

Regarding light bulbs, the situation is somewhat better because there are state financial incentives in place, as well as a facility for recycling and processing used light bulbs in the Republic of Serbia. The problem lies in the fact that the recycling centre for light bulbs. However, it is completely equipped with the latest technology, does not have a sufficiently developed collection network, and therefore not enough quantities that it could dispose of and treat (the facility also has the capacity to treat imported waste light bulbs too).

In addition to the lack of incentives, a recycling centre for batteries and an underdeveloped collection network, it is necessary to boost and systematically organize the opening of recycling yards additionally. Plus we need more containers and bins, as well as have stations we can direct people to, who are also interested in this topic. Furthermore, there is a need for continuous campaigning and education, starting from an early age.

EP: How can we increase the recycling rate in our country?

Tamara Spasenović: To increase the recycling rate in the entire country, we must first analyze the current situation in terms of different types and streams of waste, so that we can identify the key problems for each of them. We have already done this for food waste and hazardous waste streams (batteries and light bulbs, electrical and electronic waste). An initiative to solve the issue of packaging waste will soon be launched. By analyzing the current situation, and through cooperation with experts from the mentioned fields, companies, citizens and, as well as by using previously acquired experiences, we have identified key shortcomings in these areas, based on which we were able to offer proposals for adequate solutions.

Different waste streams carry different problems and require different approaches and solutions, but they all have one common denominator — the lack of a systemic solution. One of the ways to solve the issue of special waste streams to establish a collective operator based on the model that works for packaging, which would be an incomparably less burdensome model for the state, administration-wise. In this way, the rate of fee evasion would be reduced, the administration would be freed from the burden of issuing a large number of decrees, and the relevant inspection would focus on the work of the system operator.

Leading NGOs Launch Coalition to Advocate for Food Waste Policy

27.04.2023

NRDC (Natural Resources Defense Council), World Wildlife Fund (WWF), the Harvard Law School Food Law and Policy Clinic (FLPC), and ReFED have partnered to launch the Zero Food Waste Coalition, a national effort focused on informing and influencing policy at the local, state, and federal levels and sharing policy updates and opportunities for engagement with partners and stakeholders around the country. The coalition will bring consumers, businesses and government together to advocate for ambitious food waste policy solutions that contribute to the U.S. goal of halving food waste by 2030, reduce methane emissions from landfills, improve food access and nutrition security, and build more sustainable food systems.

“Changing behavior from food waste to food recovery is achievable,” said Regina Anderson, Executive Director of the Food Recovery Network. “We can reduce would-be food waste by half by 2030 if we all work together. The Zero Food Waste Coalition provides the resources we all need at any level to begin doing the right thing with our surplus food and Food Recovery Network is proud to provide step-by-step support. In time, we will be shocked that we ever threw food away at all!”

“It’s disgraceful that as millions of Americans—many of which are children—go hungry, perfectly good food is ending up in landfills. This waste is not only counterproductive to our fight against hunger, but it is also harming the environment and costing our economy hundreds of billions of dollars each year. In Congress, I have taken on this growing crisis, introducing bills to reduce food waste and correct arbitrary and confusing policies in our food system,” said Congresswoman Chellie Pingree (D-Maine), co-founder of the bipartisan Congressional Food Recovery Caucus. “The scale of the food waste crisis demands action on all fronts. So as my colleagues in Congress and I work to enact federal legislation, it’s important to have organizations on the ground engaging with and educating communities across the country to reduce waste. With the launch of the Zero Food Waste Coalition, I am confident that together, we can achieve our collective goals: reduce food waste, end hunger, and protect our planet.”

The U.S. produces and imports an abundance of food each year, but approximately 38 percent of it goes unsold or uneaten. The Zero Food Waste Coalition works to deliver on the economic, environmental, social, and public health benefits of reducing food waste. Food waste solutions can reduce the amount of greenhouse gas emissions produced throughout the lifecycle of food, conserve natural resources such as water and land which are used in the production of food, increase access to quality food, and create jobs and economic opportunity by using food as the resource that it is.

“To stop massive food waste—40 percent of America’s production—we need better labeling and more donations, as this coalition will fight to achieve,” said Senator Richard Blumenthal (D-Connecticut). “We’ll be fighting together for measures like my Food Date Labeling Act, which will help counter food insecurity and hunger as well as environmental harms.”

One of the coalition’s priorities is to mitigate food waste via the 2023 Farm Bill, a multi-year package of legislation that impacts agriculture and food issues across the U.S. Each year, farmers, food manufacturers, households, and businesses spend $444 billion to grow, process, transport, and dispose of food that is never eaten. Today, the Zero Food Waste Coalition released its top priorities for the Farm Bill, including provisions that expand federal administrative research and funding, increase grants and loans for infrastructure that eliminates food waste from landfills and for proven state and local policies that prevent wasted food, and standardize and clarify food date labels.

These priorities are included in the coalition’s April 2022 report on Opportunities to Reduce Food Waste in the 2023 Farm Bill, which provides 22 recommendations to prevent food waste, rescue surplus food, recycle food scraps, and coordinate food waste policy through the 2023 Farm Bill, based on feedback and input from more than two dozen organizations, government officials, and businesses.

“So much of the fresh produce grown on America’s farms never makes it to market, often due to small blemishes that don’t diminish its nutritional content one bit,” said Reverend Eugene Cho, President/CEO of Bread for the World. “That’s why Bread for the World endorses the Zero Food Waste Coalition’s call for the 2023 farm bill to support food recovery organizations that work with farmers to collect that produce to address hunger and improve access to healthy foods in undeserved communities.”

“The creation of the Zero Food Waste Coalition is an exciting step towards achieving zero food waste in the United States,” said Ben Crook, Vice President/GM, Hellmann’s Dressings & Condiments (NA) at Unilever. “When like-minded people, companies and governments come together to introduce programs such as these, we will ultimately be able to help change people’s behavior and have a positive impact on food waste reduction, so that we can reach our ambitious net zero goals and protect our planet for future generations.”

The founding organizations of the coalition began working together in 2020 to engage with and inform policymakers on opportunities to prevent and reduce food waste. Together, they developed and launched the U.S. Food Loss and Waste Action Plan, endorsed by over 60 companies, NGOs, and local and state governments, which recommends overarching actions the federal government can take to reduce food waste. Subsequently, coalition founders hosted a listening session in June 2022 to gather stakeholder input on priorities related to food waste, food donation, and food recovery for the 2022 White House Conference and Strategy on Hunger, Nutrition and Health.

The coalition is committed to broadening engagement on its efforts and working together with policymakers, national and local advocates, food producers, retailers, and consumers to develop and implement strategies to reduce food waste at all stages of the food supply chain.

DOMESTIC COMPANY’S INNOVATIVE SOLUTIONS FOR THE PREVENTION AND EXTINGUISHING OF FIRES AT LANDFILLS

25.04.2023

In the summer months, the entire region, and a good part of Southeastern Europe, are exposed to the constant threat of open fires. They have a devastating effect, but they are not the only threat during the summer heat. Fires at local landfills pose a huge risk to the health of people and all living things in the environment. One of the biggest fires at the local landfill happened in August 2021 in Vinča. The smoke cloud from the landfill covered Belgrade for almost three days. That summer, landfills in Valjevo, Kovin, and Niš, as well as several landfills in Montenegro and throughout the region, were burning. According to statistics, around 200 fires break out in landfills and open spaces every year in the south of Serbia.

Combustion products of municipal waste are very toxic. Depending on the composition and structure of the waste, as well as the amount of fuel and the wind direction, they can, to a certain extent, affect the health of the population that is kilometres away from the fire site, even up to a distance of 20km. Given that most of the landfills in Serbia and the region are near large towns, it is clear that the direct harmful effects of accidents at landfills on the health of the population are extremely large.

IN FOCUS:

“It’s like having an outdoor waste incinerator that has no filters, so all toxic gases as a product of incomplete combustion of municipal waste, depending on how the wind blows, are directly released in the direction of the population and businesses. A fire can last for hours or days, even weeks”, says engineer Darko Tonić, B.Sc.,TEKON’s fire diagnostics and extinguishing consultant.

A large number of fires at landfills sometimes burn imperceptibly deep, like smouldering or underground fires. They are difficult to spot, but when they surface, they are very difficult to contain and cause great problems for fire departments.

“We have all witnessed that the fire at the landfill in Vinča has been lasting for years, maybe even decades and that the fire brigades are often powerless since extinguishing with water and foam does not give good results. Sometimes it seems that applying water to the mass of burning waste causes additional fracturing of the body of the landfill, which creates new fire zones,“ explains Mr Tonić.

The outbreak of landfill fires is one of the most serious risks that landfills are exposed to during their lifetime. Landfill fires can seriously damage the existing landfill infrastructure and can threaten the lives and health of landfill employees and the population in the immediate vicinity.

Depending on the type of landfill and the type of fire, landfill fires present unique challenges for the industry and fire services. Therefore, special attention must be paid to the types of fires at landfills, their characteristics and their causes. For a landfill fire to break out, fuel, a heat source and a sufficient concentration of oxygen should be present.

New fire diagnostics and prevention technologies

Considering the current situation of a large number of landfills in the region, the number of fires and problems faced by local authorities, as well as those who manage waste at landfills, the conclusion was that it was necessary to work on projects that would alleviate and completely eliminate these problems.

The TEKON Company implements new technologies for diagnosing the state of landfills for preliminary identification of possible problems and fire prevention, which include precise measurements such as:

– the thermal measurement from the air
– measuring the concentration of landfill and flue gases
– measuring temperature in and on the landfill’s body

Measuring the landfill’s body temperature, deep and on the surface, is a generally accepted method for identifying landfill fires.

By acquiring the latest equipment that TEKON installs on its industrial drones, as well as all the required software for processing the obtained images, thermal imaging can be carried out at a number of landfills in the region.

TEKON thus uses a non-contact temperature measurement method that measures the level of infrared radiation, because it has been established that all bodies with a temperature above absolute zero (-273.15°C) emit infrared radiation, even ice. Thermal imaging cameras are specially adapted to “see” that part of the infrared spectrum that is visible to the human eye, which is why they are also called infrared cameras.

How do those cameras work?

The infrared camera, which is mounted on the drone, contains an optical system that focuses infrared energy on a special detector chip (an array of sensors) containing thousands of detector pixels arranged in a grid. Each sensor pixel reacts to infrared energy and produces an electronic signal. The camera’s processor takes the signal from each pixel and applies a mathematical calculation to create a colour map of the objects’ apparent temperature. Each temperature value is assigned a different colour. The obtained colour matrix is sent to the memory and the camera screen as a temperature image (thermal image) of that object.

Many infrared cameras also include a visible spectrum camera that automatically captures a standard digital image. Combining these images make it is easier to connect problematic areas on the thermal image with the actual equipment or the area being monitored.

Temperatures up to 50°C indicate that the landfill is operating normally. Temperatures above 50°C are considered elevated and indicate potential hot spots and fire problems. During thermal imaging from the air, the camera records the material in the internal memory, which is later processed. During this type of recording, a large number of thermal images are generated (several thousand per recorded hectare), so appropriate licensed software is a must. The results of non-contact and direct measurements are combined to give a unique temperature picture.

How small grants are helping to rescue marine habitats around the world

25.04.2023

In recent years, fishing communities in Madagascar have seen their catches dwindle, a byproduct of chronic overfishing, especially in sensitive coastal habitats like seagrass meadows.

But in some communities, fish stocks have started to rebound, thanks in part to the work of the marine conservation group Blue Ventures.

Blue Ventures has worked with national and local governments to establish locally managed marine areas, protected zones that have become a haven for undersea life.

“The communities on the tropical coast of southwest Madagascar depend on mangrove forests, seagrass meadows and coral reefs to establish a network of interlinked ecosystems that act as a base for maintenance of the rich marine biodiversity and fisheries,” said Javier del Campo Jimenez, Blue Ventures’ seagrass resident expert.

Blue Ventures is one of the recipients of a series of small grants from the International Coral Reef Initiative (ICRI) and the United Nations Environment Programme (UNEP).

The grants, which were first handed out in 2019 and have totalled USD 560,000, are funding innovative, nature-based solutions designed to protect and restore marine ecosystems, including those threatened by climate change.

The grant programme, say those involved, is a tell-tale example of how investing in the natural world can produce big dividends for both people and the planet.

The Kunming-Montreal Global Biodiversity Framework, a landmark deal adopted by 196 countries with critical goals that the world must meet by 2030 if it is to halt and reverse nature loss, also calls for the acceleration of nature-based solutions and finance to address the alarming declines in biodiversity.

A 2021 report from UNEP found that the world will need to close a USD 4.1 trillion financing gap in nature-based solutions if it is to meet its targets for climate change, biodiversity, and land degradation. UNEP’s Finance for Nature report calls for investments in nature-based solutions to triple by 2030 and increase four-fold by 2050.

The ICRI/UNEP small grants programme has supported seven projects in developing and small island states. These grants have helped to rehabilitate fast-disappearing marine and coastal ecosystems, including seagrass meadows, mangrove forests and coral reefs.

Experts say, these habitats have been under siege from a triple planetary crisis of climate change, nature and biodiversity loss, and pollution and waste.

“The health of interconnected habitats, such as mangroves, seagrasses and coral reefs is closely linked to the health of the ocean as a whole,” said Leticia Carvalho, the Head of UNEP’s Marine and Freshwater Branch. “On this International Mother Earth Day, let’s remind one another how vital a healthy ocean is to the well-being of all life on Earth.”

The pressures on both marine and terrestrial ecosystems are pushing an estimated one million species towards extinction, a decline that researchers have called “unprecedented.”

One of those species under threat is the scalloped hammerhead shark. The animals, which are endangered according to the International Union for Conservation of Nature, often become fatally tangled in fishing nets.

To help save the animals, Mision Tiburon, another recipient of the UNEP/ICRI grant programme, has helped to restore degraded mangrove forests in the northern Golfo Dulce in Costa Rica. The mangroves – salt-water loving trees that sit partially submerged in the ocean – are a habitat for juvenile scalloped hammerheads.

“The restored mangroves in Golfo Dulce area are nursery grounds that offer food and protection to the juvenile scalloped hammerhead sharks from predators,” said Ilena Zanella, the Director of Mision Tiburon. “The societal awareness on shark conservation via mangrove restoration and ocean literacy provides [local communities] with an opportunity to protect these endangered species for the future of our planet.”

SCOBY — INSPIRATION IN A GLASS OF KOMBUCHA

24.04.2023

Screenshot 2023-04-24 125047 — Photo: Pexels/Kind

Chances are you’ve heard of kombucha, a drink made from green or black tea with added sugar and bacteria or yeast. You may have even wanted to check out its widely known medicinal properties, which referential laboratories now confirm. Or, during preparation, you were repulsed by the gelatinous lump that formed on the surface of the container as a result of the fermentation process. This gelatinous mass gave a completely different ecological idea to an artist from Novi Sad.

Adrienn Újházi is a painter who examines the relationship between man and nature in her artwork. She also advocates a special artistic practice called bio-art, which implies using of biotechnology and organic material suitable for different media such as painting, drawing, video and installation. Her goal is not only artistic but also ecological. Adrienn wants to create, but in such a way that synthetic materials are used only when necessary and that her artwork creates minimal waste. In her interview for Energy Portal Magazine, Adrienn reveals her research journey from kombucha to SCOBY and what she learned along the way.

EP: How did you come up with the idea to make SCOBY?

Adrienn Újházi: Every summer I spent at least 2 to 3 months with my grandparents in the countryside. For most of that time, I was surrounded by plants and animals that became the main inspiration for my creation in the field of visual art.

I wanted to use as few synthetic materials as possible in my work and produce as little waste as possible. That’s how I came across the kombucha drink. This drink was mostly consumed in the second half of the 20th century, and in almost every house, there were several bottles of this liquid with the SCOBY culture. My further research into this material officially began when I made the first round of this drink.

IN FOCUS:

EP: Could you describe how is this material made and its use?

Adrienn Újházi: Kombucha is obtained through fermentation, usually of black or green tea. During this process, microorganisms are activated, and a bio-film is created on the liquid’s surface, resulting in the SCOBY material, an acronym that actually means ‘symbiotic culture of bacteria and yeast’. Another name for this material is bacterial cellulose. The material can be treated in a number of ways — dyed with different pigments, dehydrated and transformed into a fixed state, as well as mixed with other, different natural materials.

The goal of this process and research is to find suitable biodegradable resources, like SCOBY. The choice of material is correct if, through a natural process and with the help of bacteria, the mushroom becomes degradable, i.e. after a certain time, it starts to decompose. This kind of processed material can be used for different purposes. One example of its potential global application is the alternative to “vegan leather”, which is made exclusively from plant and organic materials. The material can be used in different spheres of design such as packaging and interior design.

EP: How do you plan to present it to the general public?

Adrienn Újházi: The material has been presented in different forms so far. I started to promote it through my artistic practice and present its character in different media. It mainly includes two-dimensional works in smaller and larger formats, photo and video documentation, audio, light boxes, prototypes like bio hats and smaller experimental pieces in Petri dishes, ready-made objects and more.

Opportunities for promotion were mainly at cultural events and other types of events in Serbia and abroad. These were mostly activities that were realized in cooperation with non-governmental organizations, institutions, curators and artists in the form of individual or group exhibitions, biennials, art fairs, open discussions, panel discussions, lectures and workshops.

EP: Do you expect this material to be widely used in the future?

Adrienn Újházi: Disseminating information and education is necessary for people to understand the benefits of such materials. We are currently working on it, and we have noticed that there is, albeit a small, circle of interested people who are ready to explore. That is why I believe that the SCOBY material has the potential for widespread use. At the same time, more experts, time and resources are needed to achieve this goal. I am very grateful that, thanks to the cooperation with my friends and colleagues, I can implement the first project based on promoting sustainable materials like SCOBY. The project is called BIOFABRIKA and was implemented through the ReAktor Citizens’ Association and is supported by the European Capital of Culture — Novi Sad 2022 Foundation.

Air pollution levels across Europe still not safe, especially for children

24.04.2023

While emissions of key air pollutants have declined over recent decades, air pollution levels in Europe are still not safe. Children and adolescents are particularly vulnerable to air pollution because their bodies, organs and immune systems are still developing. Air pollution damages health during childhood and increases the risk of disease in later life, according to the EEA ‘Air pollution and children’s health’ briefing.

Air pollution is estimated to cause over 1,200 premature deaths every year among those under the age of 18 across the EEA’s 32 member countries. Although the number of premature deaths in this age group is low relative to the total for the European population estimated by EEA each year, deaths early in life represent a loss of future potential and come with a significant burden of chronic illness, both in childhood and later in life.

Children’s lung function and lung development are affected by air pollution, especially by ozone and nitrogen dioxide (NO2) in the short term, and by fine particles (PM2.5) in the long term. Maternal exposure to air pollution during pregnancy is linked to low birth weight and risk of pre-term birth. After birth, ambient air pollution increases the risk of several health problems, including asthma, reduced lung function, respiratory infections and allergies. It also can aggravate chronic conditions like asthma, which afflicts nine percent of children and adolescents in Europe, as well as increasing the risk of some chronic diseases later in adulthood.

Until air pollution is reduced to safe levels overall, improving air quality around settings like schools and kindergartens and during activities like school commutes and sports, can help reduce children’s exposure.

EEA monitoring update 2022: air pollution levels remain persistently high

In 2021, upwards of 90 percent of of the EU’s urban population was exposed to harmful levels of nitrogen dioxide, ozone and fine particulate matter (PM2.5).

PM2.5 is one of the most damaging pollutants to human health, with exposure to PM2.5 a leading cause of stroke, cancer and respiratory disease. In 2021, 97 percent of the urban population was exposed to concentrations of PM2.5 above the 2021 WHO annual guideline of 5 µg (microgram) /m3.

According to preliminary data from 2022, central-eastern Europe and Italy reported the highest concentrations of both PM2.5 due primarily to the burning of solid fuels like coal for domestic heating and their use in industry.

The EEA briefing ‘Europe’s Air Quality status 2023’ presents the status of concentrations of air pollutants in 2021 and 2022 for regulated pollutants, in relation to both EU air quality standards and the 2021 WHO guideline levels.

How clean is your city? Portuguese, Swedish cities score cleanest air

Faro, Portugal, and the Swedish cities of Umeå and Uppsala were ranked as the cleanest European cities and had the lowest average levels of fine particulate matter, or PM2.5, over the past two calendar years, according to the updated EEA city air quality viewer. Cities are ranked from the cleanest city to the most polluted, on the basis of long-term average levels of fine particulate matter.

Background

Under the European Green Deal’s Zero Pollution Action Plan, the European Commission set the 2030 goal of reducing the number of premature deaths caused by PM2.5 (a key air pollutant) by at least 55 percent compared with 2005 levels. To this end, the European Commission published in 2022 a proposal to review the ambient air quality directives, aiming, among other things, to align the air quality standards more closely with WHO recommendations.

The EEA’s air quality assessments highlight pollutants deemed to be most harmful to human health or that exceed the EU air quality standards and WHO guideline levels most frequently. The concentrations are obtained from measurements in over 4,500 monitoring stations across Europe that are officially reported to the EEA by its member and other collaborating countries.

WASTEWATER TREATMENT AND PRESERVATION OF FRESH WATER SOURCES

23.04.2023

Snimak ekrana 2023-04-21 212206 — Photo: Pexels

There is increasingly less drinking water on our planet, and serious global conflicts over drinking water are looming on the horizon, as the global crisis is already widely present due to the increasingly difficult provision of the basic needs of the human community, primarily the population living in the planet’s southern hemisphere. The uneven distribution of water resources (unevenness of water flows per unit of time) determines the availability of fresh water, which is one of the most significant limiting factors in development worldwide.

Due to insufficient reliability in providing the required annual quantities of drinking water for its population, this is a dominant item in strategic planning in the most developed countries. According to statistical data, Europe, for instance, has only 8 per cent of the world’s renewable freshwater resources, and at the same time, participates with 15 per cent of the total world consumption. The availability of quality water varies significantly within the same region, and in addition to natural factors such as geographical location, relief, precipitation and air temperature, the quality of water resources is also influenced by various anthropogenic factors.

According to the data collated by the Serbian Hydrometeorological Service (RHMZ), climatic influences in Serbia imply a constant and slight increase in air temperature in the last 40 years (according to statistical data starting in 1983), as well as the trend of decreasing precipitation in summer and increasing precipitation in winter months. We can conclude that these are not the exclusive, nor the dominant factors jeopardizing the supply of water resources in this region.

IN FOCUS:

Waste of anthropogenic origin is the biggest problem causing the pollution of both surface and underground watercourses. In contrast to European countries, where 40 to 90 per cent of the generated waste is regulated, starting from separation, through reuse and treatment, to the full implementation of the circular economy principles, in Serbia, only 8 to 10 per cent of the generated waste is regulated. These most often include sanitary landfills, but without adequate segregation and regulation of leachate, with a very small per centage of reuse, recycling and creation of competitive market products.

Also, in addition to the discharge of municipal water into surface watercourses without prior treatment, the key sources of pollution are untreated industrial wastewater from various industrial plants, mine water, agricultural waste drainage water, and pollution created by thermal power plants and river navigation. Serbia needs to protect the space and catchment underground water areas, as well as existing and planned accumulations of surface water. The goals of the EU directives that are valid until 2030, then until 2040 and 2050, are also partly ultimatums for Serbia.

Wastewater treatment enables the preservation of freshwater sources and increases the capacity for their use. The implementation of the circular economy principles in the processing of wastewater from water supply systems should result in the reuse concept, which becomes the realized value of wastewater because it transforms the expensive wastewater treatment service into a self-sustaining service that generates economic importance.

Conventional water supply systems in Serbia process water mainly from surface watercourses by intaking water from a specific reservoir, through PH value correction (alternatively), purification, filtration using sand filters and mandatory chlorination. In the Belgrade water system, river and well water are purified in a somewhat more contemporary way via ozonation, UV disinfection, filters with activated carbon and using tuff in the treatment of river water, while the purification of well water begins with aeration.

What is common to all drinking water processing plants is maintenance, the so-called washing of filter installations with clean processed water. During the process, a certain amount of wastewater is created, used for its own consumption. Own consumption, depending on the degree of filter dirtiness, amounts to 4–17 per cent of the total produced water at the given plant. This means that, for instance, a plant that produces 1500l/s, i.e. about 4,000,000m³ per month and about 48,000,000m³ per year, can use up to 7,000,000m³ of clean water annually for its own consumption.

The public enterprise Belgrade Waterworks and Sewerage washes its filters one by one (two or more filters cannot be washed at the same time) in the following way — after purging it with air, the filter is washed with water at a flow intensity of 570l/s, between 20 and 25 minutes, until the turbidity value reaches 0.1NTU, where 700 to 900m³ of clean water is consumed per filter.

As the filter washing water goes directly into the sewage system, a turbidity/NTU test was performed by an accredited laboratory during the washing of filter installations which determined that after 4 minutes, the microbiological tests, it was concluded that only 15 per cent of the filter washing water has elevated parameter values compared to the recipient’s raw water, while 85 per cent of the wastewater is within the parameters of the recipient’s water (if, for example, 700m³ of washing water was used which means that 595m³ does not differ in quality from the incoming water at the intake).

WORKING DAILY IN PEOPLE’S BEST INTERESTS AND PRESERVING THE ENVIRONMENT

22.04.2023

SCR-20230421-mybp — Photo: Pirot Regional Landfill

Our planet is facing major environmental challenges. Awareness of how important environmental protection is for our future has been growing, so a new economic model, such as the transition to a circular economy, with waste reduction and resource conservation, is being imposed as an indispensable prerequisite for further sustainable development worldwide. The natural order implies primary prevention and adequate management of waste, its reuse, recycling and disposal.

The most advanced regional sanitary landfill in our country is located in the town of Pirot, which treats waste both from Pirot and nearby towns of Babušnica, Bela Palanka and Dimitrovgrad. After three years of operations, and all the energy and effort invested in this project, the positive effects are multiple.

Director of the Public Utility Company Regional Landfill Pirot, Nebojša Ivanov, is happy with the company’s results. He underlines that the landfill did not negatively impact the environment in any way, highlights the experience they have gained in non-hazardous waste management, and mentions a financial profit that they have channelled into further investments in infrastructure and its development in the segment of non-hazardous waste management.

IN FOCUS:

EP: Earlier, you announced that, during the second work phase, a second cell will be built on the landfill while the first cell would be rehabilitated. How far have you come with that? When will the second cell be commissioned?

Nebojša Ivanov: The European Bank for Reconstruction and Development has approved a loan to the Ministry of Environmental Protection to be used for the construction of the second cell, rehabilitation and reclamation, i.e. closure of the first cell. The operational talks are concluded, and I hope that we will sign the contract in the next few months. We spent the previous period talking with consultants, and the activities on closing the first cell and building the second should commence in early 2023. Our goal is not to constantly build and fill cells with municipal waste. Our idea is to drastically reduce the amount of municipal waste that we dispose of.

EP: What can you tell us about the regional recycling centre?

Nebojša Ivanov: In 2017, the town of Pirot and the landfill applied for the funding of the Primary Selection Project, which is financed from IPA funds, and we started the implementation phase. To be selected for the implementation of the primary selection process for the Pirot district, which value, according to our project, is 1.4 million euros, the main prerequisite was that there was a secondary separation line.

In late 2018, we started drafting project documentation, and in early 2019, we received a building permit to construct a secondary separation line. In mid-2019, we commenced construction work, including the construction of a hall, supporting facilities, the entire infrastructure (electricity, water, sewage, and wastewater), and the installation of the required line.

The project was completed in February 2022, and the secondary separation line has been operating at full capacity since mid-April.

The total amount paid to suppliers and contractors was 264 million dinars, including VAT, of which the Ministry of Environmental Protection provided 164 million dinars, and the landfill provided 100 million dinars from its own revenues.

We are currently putting together the documentation for obtaining a use permit, i.e. we will become a public facility with a use permit, which just demonstrates that we have successfully completed the entire project

EP: The Pirot regional landfill is the only landfill of this type in Serbia.

Nebojša Ivanov: Exactly! I am proud of everything that has been done so far – now, we have a cell, the special secondary separation line. Since September, we also have a primary waste separation line that works at full capacity. We also adequately manage packaging waste and municipal packaging waste. Furthermore, we are embarking on building a composting plant under the auspices of the project financed from the EBRD loan, through the Ministry of Environmental Protection, the value of which is around 3.5 million euros. We also have project documentation and a building permit in place.

A composting plant is the next logical step because as much as 40 per cent of the received waste is biodegradable, which, when processed, can be sold as high-quality fertilizer. This also reduces the amount of waste deposited at the landfill.

The landfill has a comprehensive monitoring system that monitors and acts preventively on the recirculation system, which has flowmeters, an isometric grid, a process water quality monitoring system, and a meteorological station. We do a lot of work, and I think we are an example of good practice, perhaps the best in the region. For instance, a country like Croatia does not have a secondary separation line like ours. We built the landfill based on the project from Szeged

EP: How will you further help the citizens and involve them even more in your campaigns?

Nebojša Ivanov: We need to create an infrastructure that will help citizens adequately participate in the primary waste selection. With our activities, we try to gain their trust, and we want our citizens to be sure that their efforts in separating packaging, glass and cardboard are valued. Citizens should know that separated waste does not end up at the landfill, but is transported to the secondary separation centre.

Furthermore, we have been talking to the mayor about an additional stimulus for citizens. The idea is that each household gets two bins for the primary selection of waste — dry and wet — and residential communities are given proper containers. Dry waste includes recyclables such as paper and glass. All bins and trucks will be chipped so we will know exactly how much waste each person has left and their utility bill will vary accordingly. The investment in chips is not big, but it stimulates citizens to treat waste properly and is effective. The household should not pay for waste removal based on its size or the number of household members who live there, but on the quantity of wet waste they dispose of, and the waste removal bill should reflect that.

We want to see as little municipal waste as possible being deposited at the landfill, and as much of it recycled as possible. We want to motivate citizens to participate more in the primary waste selection. It would be good to launch a media campaign and we also need to apply the good examples we have seen in European cities. It is important to point out that this is a financial investment that we can afford.

CHARGE&GO IS EXPANDING THE CHARGING NETWORK

21.04.2023

The first thing that comes to mind when you think of an electric vehicle is where to charge it! A well-distributed charging network is essential for electric car drivers to plan their journeys. The first digital platform and application, Charge&GO, is available for quick and easy finding electric chargers and simple charging.

They contribute to the development of electromobility in our country by promoting and installing chargers. So far, electric chargers with power from 22 to 180 kW have been installed at more than 40 locations on the roads and highways of Serbia, and by the end of the year the network will cover as many as 100 charging points where there will be more and more fast high-power chargers.

Following the successful beginning of the year when the company Charge&GO put into operation a 120 kW electric charger at the OMV gas station in Lapovo, at the beginning of July, the strongest charger for electric vehicles in their network was installed at the OMV gas station Martinci 1, in the direction to Belgrade.

IN FOCUS:

The charger on this gas station has an output power of 180 kW, and its maximum power is 300 kW. The plan is to gradually increase that power to its total power by simply adding energy modules. The Unity 180 charger, manufactured by Kostad Siemens, is manufactured in Austria and operates at temperatures ranging from -30° to +50° C. It supports the CCS standard for DC charging, and the output power, if both CCS ports are in use simultaneously, is 2 × 90 kW.

Owners of electric vehicles have the opportunity to use other ultra-fast chargers located at OMV gas stations: in Doljevac, on the Niš-Vranje highway, where a 150 kW ultra-fast charger has been installed (the second most powerful electric charger available at OMV gas stations), at Gradina, the border crossing near Dimitrovgrad (90 kW), as well as in Bačka Topola where there is another Unity 180 kW.

New charging points in retail chains

In addition to the strategic expansion of the network of ultra-fast chargers on highways, the hardworking employees of the company Charge&GO are also installing chargers at the Stop Shop retail chain locations. From the beginning of August, drivers of electric vehicles can stop by the Stop Shop in Sremska Mitrovka, Lazarevac, and Požarevac and recharge their batteries Since September, a 120 kW charger has been operating in the parking lot of the Stop Shop in Vršac. It is expected that power chargers in the range of 24 to 120 kW will soon be put into operation at other Stop Shop locations throughout Serbia. Electric car drivers know that the Charge&GO network map is the easiest way to locate all chargers. We should mention fast and ultra-fast chargers at GAZPROM gas stations and four toll booths on the highway near Vrčin, Horgoš and Trupala-Niš. Schneider Electric AC chargers are available in Novi Sad and Kragujevac, in the Promenada and Big Fashion shopping centers. The Charge&GO network was also chosen by representatives of the automotive industry in Serbia, such as British Motors, AK Kompresor and Hit Auto.

What does the Charge&GO platform offer?

The Charge&GO digital platform and application allow drivers of electric vehicles to locate the nearest chargers easily and charge their cars quickly and easily. The platform provides drivers with an efficient service for charging and paying for the use of charging points, as well as the ability for companies to manage their charging network remotely. It includes several services, such as charging control, charger monitoring, pricing, usage restrictions and charging session overview.

The easiest way to check the locations and availability of chargers in this network is the Charge&GO application. Although all chargers can be accessed in multiple ways (via QR code or charger number), if you download the app, you automatically get a lower price, GPS navigation directions and access to an incredibly extensive network of 170,000 chargers in 30 countries across Europe.

WWF IS LOOKING FOR CREATIVE PROJECT IDEAS FROM THE CIVIL SECTOR

20.04.2023

serbia_srbija_nature_priroda_drina_river_reka — Photo-illustration: Pixabay

On our way to joining the European Union, among the most important steps are our answers and solutions to the problems of environmental protection and climate change in the field of legislative frameworks and strategic plans. It’s off to a good start. A solid strategic and legal framework for the environment and climate change has been prepared, but the implementation is slow.

There are also numerous environmental problems: water and air are polluted, waste is inadequately managed, natural resources are being depleted, and environmental protection is in last place. Although there are a lot of local movements, civil society associations and activists who try to contribute to changes and implementation of adopted policies in the field of environmental protection, very few of these organizations are sufficiently developed to influence the creation of policies. Only a few organizations have the potential for effective engagement and influence on decision-making. At the same time, the majority base their work on activism and have modest capacities for wider action and influencing public processes.

Effective and lasting problem solving can only be achieved through well-structured processes, where strong and credible civil society organizations participate as equal partners to government institutions. Among them is certainly the World Environmental Protection Organization WWF Adria Serbia, which started the implementation of the project “Serbia Actions in the Field of Environment and Nature and Climate — Safe Nature and Climate”. The project was supported by the European Commission through the Civil Society Support Program and is a direct response to Serbia’s common challenges for global efforts to mitigate and adapt to climate change.

IN FOCUS:

Goals and conditions of the current project

The strategic grant program is a WWF project whose goal is to form a network of civil society organizations in Serbia that will implement sustainable ideas in the field of environmental and climate protection. The project’s main goal is to increase civil society organizations’ influence and capacities in dealing with reform and integration processes in the EU in the areas of environmental protection and climate change. Civil society organizations can apply if they have project proposals that contribute to the following goals:

Improving the capacity of representatives of civil society organizations to monitor local and national policies and regulations in the field of environmental protection and climate change
Research and analysis of gaps in policy management and regulatory frameworks related to environmental protection and climate change mitigation
Advocacy for correct and effective local and national environmental protection and climate change policies
Promoting dialogue and active engagement of citizens as a prerequisite for setting up effective environmental reforms and policies for EU accession
Raising awareness of the importance of establishing correct and effective environmental protection and climate change policies that enable the development of a sustainable ecosystem in the Republic of Serbia.

The project lasts until 2025, and a new call will be announced yearly. Anyone who meets the requirements can apply for a grant in the maximum amount of 18,000 euros. The program is designed in such a way that an organization can apply in the following year with the continuation of the same project or with a different project, but so that the total amount of the grant in these three years does not exceed 40,000 euros.

SOLUTIONS OPTIMISING BUILDING EFFICIENCY

18.04.2023

Screenshot_21 — Photo: Schneider Electric

So far, the importance of digitalisation in business has been discussed on multiple occasions. This time, we aim to focus on building digitalisation and how it can help building owners and maintenance teams make the right decisions and reach their sustainability goals.

This is how Miloš Vuksanović, Sales Director for Commercial and Industrial Buildings, Serbia and Montenegro, Schneider Electric, starts his story about the importance of open BMS platforms and connected smart buildings. EcoStruxure™ Building Operation, as part of the EcoStruxure™ Building solution, is such a platform. In the anniversary year — 20 years of Schneider Electric’s operation here, Miloš Vuksanović talks about the significance of meeting sustainability goals and ways to achieve them.

“Our experience in industrial optimisation has confirmed the importance of openness, connectivity and interoperability of platforms, whose functions allow machines to work together in resolving the most complex issues organisations encounter on a daily basis”, explains Vuksanović at the beginning, add that these features are equally important for modern buildings and, as such, are an example of how to achieve zero CO₂ emission.

IN FOCUS:

“To keep global warming at 1.5 °C, it is vital to reduce GHG emission to 45 per cent by 2030 and reach net zero by 2050. Buildings emit nearly 40 per cent of CO₂, and building owners and managers have to find a way to minimise CO₂ emission as soon as possible.” Vuksanović refers to the Paris Agreement.

Schneider Electric believes that new and existing buildings must focus on modernisation, including their transformation to fully electric and fully digital. According to him, it means turning all fossil-fuel-based consumption — such as heating — into a more efficient electric methodology. It also means that with digitalization we receive data to use further for a deeper insight and control of buildings, costs, and efficiency.

Explaining how it functions, Vuksanović says that everything is based on collecting information and the use of automation, acting unanimously to achieve these ambitious goals. In that respect, he points out several items requiring it:

Systems in a building that communicate mutually — when all systems of a building that exchange information are really integrated and connected, the building maintenance team is enabled to make better decisions.
The flexibility of a system to adapt and respond to the needs of owners, tenants, and society as a whole today, as well as in the future.
Achievement of the full potential of all available data.

“New generations of the Building Management System respond to all these needs, and their implementation results in developing buildings of the future. A modern open BMS offers connectivity, interoperability and intelligence. It helps all devices in a building be connected into a shared control centre for managing all operations”, Miloš Vuksanović underlines.

He points to the solution of new generation smart buildings available today, including one from Schneider Electric’s portfolio.

ENVIRONMENTAL PROBLEMS CAN ONLY BE SOLVED THROUGH A JOINT EFFORT

17.04.2023

cup-čaša-plastika — Foto-ilustracija: Pixabay

The waste that we create every day ends up in a couple of thousands of unregulated landfills and dumps all over our still beautiful country. What is waste? The Serbian Environmental Protection Agency’s (SEPA) website states that waste is any material or object created during production and service activities, as well as objects that are no longer in use or are not fit for further use and must be discarded. Therefore, waste is not only things that end up in the bin.

We have spoken with Stefan Simeunović, Director of the Serbian Environmental Protection Agency, about the current situation regarding unregulated landfills and polluters in the digitalization era and how to create a cleaner environment.

EP: Unregulated landfills are one of the biggest environmental problems in Serbia. How many unregulated landfills are there in our country, and what is the solution to this problem?

Stefan Simeunović: The data submitted to the Serbian Environmental Protection Agency by local governments show there are over 2,600 unregulated landfills throughout Serbia. Estimates are, however, that this number is almost 3,500 unregulated landfills and dumps all over the country, as well as that a fifth of the total generated municipal waste ends up in those locations. That is why unregulated landfills are one of the biggest environmental problems in Serbia.

Both last and this year, the Ministry of Environmental Protection launched two public tenders for cities and municipalities, which secured the co-financing of projects to remove unregulated landfills. Once the projects based on those tenders are implemented, close to 700 unregulated landfills will have been removed country-wide.

To preserve already cleaned locations, the Ministry also provided funds for video surveillance that local self-governments install on cleaned locations, providing certain technical requirements are met.

The Ministry’s competitions are extremely important because they encouraged cities and municipalities to think more about the problem created by unregulated landfills, to nominate projects and, with the support of the state, to finally come to grips with this problem that spans several decades.

IN FOCUS:

EP: Construction waste is a big segment of the waste deposited in unregulated landfills. How should both individuals and companies properly dispose of this type of waste? How do large companies in Serbia dispose of their waste?

Stefan Simeunović: There are two types of construction waste — non-hazardous waste that is similar in composition to municipal waste (recyclable, inert, etc.) and hazardous waste that requires special treatment (contains asbestos, a lot of heavy metals, etc.) to which special regulations apply.

The Law on Waste Management and by-laws prescribe that public utility companies cannot be engaged in the disposal of industrial waste, because they are solely responsible for providing utility services and the like. Companies with the appropriate license to remove industrial waste should be engaged, and appropriate documents should accompany each transport of waste.

Both national and local inspections are in charge of checking whether the company has properly disposed of its waste.

EP: In the future, polluters in all Serbian cities and municipalities will have to submit data relating to their negative impact on the environment to local governments in a digital format. What benefits does the digitization of this data create?

Stefan Simeunović: Earlier this year, the Serbian Environmental Protection Agency launched an important project called Green Digitalization, which was started and is being carried out by our employees as part of their daily activities. The project’s goal is to increase the efficiency and effectiveness of the National Registry of Pollution Sources by implementing innovative technologies, providing additional training for employees, improving the safety and reliability of the information system, as well as communicating with users.

The complete digitization of the National Registry of Pollution Sources is an essential process that should lead to the higher efficiency of the Registry’s administrators, facilitate reporting to entities that must submit data to the National Registry, and also satisfy the public’s need for environmental information.

Digitalization is a prerequisite for successful communication with legal entities and small business owners who are required to report to the National Registry. The significance of this project is best illustrated by the fact that every year the Agency collects over 180,000 reports related to environmental pollution that are stored in the National Registry, which annually generate more than 250 boxes of archived documents. The project eliminates paper reports which are now submitted online.

Regarding the communication between the Agency and users, and under the auspices of the Green Digitalization project, we have established an efficient Customer Care Centre, which provides significant support for businesses, as it deals with over 20,000 inquiries every year.

Creating a new module of the National Registry will boost the availability of data to all interested parties, which is in accordance with the Aarhus Convention.

PERFECT TIMING AND THE RIGHT PARTNER FOR BUILDING A SOLAR POWER PLANT

16.04.2023

solar, obnovljivi izvori — Photo-illustration: Pixabay (mrganso)

Just ten years ago, the use of renewable energy sources in Serbia was negligible. Here and there, we came across projects of solar power plants for personal use, either on a holiday home in the form of an off-grid system with which the owners solved their electricity needs where there was no grid or on the roof of a company where they visionarily decided to invest and reduce their bills for electricity.

The legislation did not exist, and nobody thought about incentives. It was only in 2017, when the EPS adopted the Rulebook on the operation of the distribution system, that the first positive steps were taken, and the electricity market was formed. During that period, more and more private individuals invested in power plants for their own needs, still not knowing when the investment would pay off.

In the following years, things changed significantly. On the market, there were not only power plants for investors’ own needs that were connected without procedures, but more “sustainable projects” appeared — power plants that deliver excess electricity to the grid and sell it to the electricity supplier.

IN FOCUS:

The adoption of the Law on the Use of Renewable Energy Sources last year announced a new incentive program for renewable energy sources and increased workload for companies engaged in the design of RES power plants, primarily when it comes to wind farms and solar power plants. Soon afterwards, we found ourselves in the middle of an energy crisis, which served as an additional incentive for the transition to renewable energy sources.

The industry has a hard time accepting price jumps and reacts to drastic changes by turning to more efficient solutions. This is exactly what happened, so companies increasingly agreed upon the design and construction of power plants with firms that are their comrades on this path of transition. The CEEFOR company has been operating on the choice of construction, the slope of the panels and the surrounding soil.

The Toyo Tires solar power plant will cover 8.2 hectares. The annual production of electricity will amount to 10,148,927 kWh, which will contribute to the saving of 8,119,141 kg of carbon dioxide on an annual basis.

Along with the design of the solar power plant, CEEFOR was in charge of preparing the documentation needed to obtain a building permit, which was a challenge because it is a power plant with a capacity of over 1 MW that will be located on the ground, and a simplified procedure was not applicable in this case.

All the necessary steps, information on the location, geomechanical studies, obtaining an opinion for connection and conditions for design and connection from the electricity distribution company, then obtaining location conditions, development of all necessary projects, creation of environmental study, obtaining an energy permit, can be extended for several months. However, thanks to the good cooperation with the investor, local authorities, and all competent institutions, all the mentioned steps were completed in record time so that the investor (as well as the state) could start using the benefits of solar energy. for more than ten years. During its first decade, it tried to enable its clients and partners to reduce electricity consumption, as well as to contribute to the preservation of the environment with significant financial savings. CEEFOR offers its clients consulting and design services in the field of renewable energy sources, and their reference list is exceptional.

The Toyo Tires company recently joined this list, for which CEEFOR designed the Toyo Tire Taiyo solar power plant, with a total power of 8.4 MWp. The project included bifacial solar panels that enable the production of electricity from the rear side as well, thereby increasing the total output power of the individual modules. They are an excellent choice for power plants on the ground because they increase the output power by up to 20 per cent, depending The plan is for this power plant to acquire the status of a prosumer, that is, to use green electricity for their own needs. At the same time, all excess will be handed over to the electricity distribution network.
