It is well-known that organic wastes emit certain amount of greenhouse gases. Waste-to-energy is a startup which aims to collect organic wastes (especially food remainings, food scraps) from restaurants, cafes, canteens etc. and produce electrical, thermal energy and a fertilizer of a good quality in the biogas plant. So, constructing the biogas station we reduce CO2 emissions from two directions: energy production and making mineral fertilizers. What does it mean? We reduce 1583 tons of CO2 per year by producing electricity on biogas plant. Very much energy is used when mineral fertilizer is produced. Also a big amount of CO2 is reduced when instead of using mineral fertilizers farmers use digestate, which outcomes after production of biogas.
