The application of selected ideas will help reduce the amount of waste by better procurement planning, separation of recyclable waste, use of biodegradable waste for the production of compost for fertilizer, pellets and briquettes for energy production, but also soap and edible oils.

These innovative solutions will also contribute to the reduction of greenhouse gas (GHG) emissions and pollution, as well as the development of the circular economy in Serbia.

Thanks to the idea of ​​JKP "Higijena Pancevo", a system of separation of communal waste in individual households will be introduced in Serbia for the first time. It will cover 300 households in the "pilot zone" of the city. Each of these households will receive a home composter, in which food waste and green waste are disposed, and the compost that is created in that way can be used as fertilizer. In addition, households will receive a container for separating PET packaging and a container for mixed municipal waste, while they will also be able to dispose of glass at common street checkpoints. "Higijena Pancevo" will measure the amount of waste collected in this way and keep electronic records about it, so that households would pay for the garbage collection service according to the amount of mixed municipal waste they throw away.

In the vineyards on the territory of the municipality of Vršac, large amounts of waste are generated from the branches, which mostly end up in landfills or are set on fire. Dairy "Petrov" from Veliko Središte near Vršac came up with the idea to produce bio-pellets from that branch, which it will use as fuel for the needs of dairy production. This dairy is already baling and using straw from its farm for that purpose, but they decided to introduce a new practice, because pellets from grape residues have a better caloric value than straw. This will produce more energy with fewer raw materials.

The civil society organization BIOIDEA, in cooperation with the Institute of General and Physical Chemistry from Belgrade, has devised a way of making soaps and candles from edible waste oil at home. They will distribute 2000 containers of zeolite to interested citizens of Belgrade and Sjenica free of charge, in which the oil used for food preparation can be purified, as well as a recipe for making soap. The organization will also train women living in rural areas of Serbia to make soaps and candles from edible waste oil for marketing, in order to provide themselves with a source of income.

The company "Agrose" from Mladenovac, which is engaged in the production of jams and fruit puree service, will produce various types of edible oil for human use, as well as flour that can be used as a supplement to animal nutrition, from the stones that remain after fruit processing. In this way, it will reduce the amount of food waste generated in the fruit processing chain.

The company "Hyperether" from Novi Sad will develop a mobile application based on the principle of artificial intelligence, which will contribute to the reduction of food waste by monitoring when the expiration date of food in the refrigerator, and warn users of the application to use it on time. photos of food in the refrigerator, and will offer customers recipes for preparing meals from the food available to them. For citizens, the application will be available free of charge, while hotels, restaurants and cafes will be offered a commercial version, for better procurement planning.

In order to make the most of biodegradable waste from landfills, JKP "Regional Center for Waste Management Duboko Uzice" will produce pellets and briquettes from larger pieces of wood, and decorative and decorative mulch from the remains of wood. At the landfill itself, they will open a composting plant, where all other biodegradable waste will be processed into quality compost, which is used as fertilizer.

The Bio-Waste Management Challenge project is implemented by the United Nations Development Program (UNDP) in partnership with the Ministry of the Environment, with financial support from the Swedish International Development Cooperation Agency (Sida).
