The best way to use meals waste for vitality

Every autumn, the authorities appeal to farmers not to burn stubble because, in addition to causing fires and endangering their lives and the lives of others, they also reduce future yields. And the harvest residues could be used.

“So, to use the harvest residues from two and a half million hectares of arable land and produce three billion cubic meters of gas and 7.5 million tons of the highest quality humus to improve the quality of agricultural land. There is no designed strategy for what we call waste, which is for someone else’s raw material,” says prof. Dr. Miladin Ševarlić, President of the Association of Agricultural Engineers and Technicians of Serbia.

About two million tons of organic waste are thrown away in Serbia annually. It turns into methane in landfills, causes fires and pollutes the soil, groundwater and air, instead of being used to produce biogas.

“When we talk at this moment in the construction and use of biogas, we must keep in mind the fact that these are primarily facilities that help protect the environment, reduce pollution of waste water, soil and air, and in this way we primarily remove organic pollution and methane, which is 25 times more dangerous from carbon dioxide itself when I talk about climate change,” says Dr. Slobodan Cvetković from the Institute of Chemistry, Technology and Metallurgy of the University of Belgrade.

Germany has 12,000 biogas plants.

“Most of those plants use agricultural waste. Organic waste from households, shops, restaurants, and the food industry is also used. It is very profitable. The investment can pay off in as little as three years. Since Serbia has a huge amount of waste that is not collected, it could cover all your gas needs,” says Rafael Fitz, Director of Wabio Technology GmbH Munich.

The sugar factory in Vrbas uses sugar beet residues to produce biogas with the application of German Wabio technology.

“Vabio technology can use harvest residues from agriculture, sludge from wastewater treatment plants, it can use the organic part of municipal waste, that means all the food that we throw to rot on the ground today can use industrial biomass Duško Bošković, director of the company “Vabio Investment Holding”.

And we throw away 83 kilograms of food per inhabitant per year, which, according to the United Nations Environmental Protection Program, is nine kilograms more than the world average.
