The research on efficiency of biogas production from organic fraction of municipal solid waste mixed with agricultural biomass

key words: Biogas, organic fraction of the municipal waste, methane fermentation

Summary:

Increase of waste and pollutants which degrade the environment is the main problem of civilization in twenty-first century. In the twentieth century it was observed, that amount of waste from agriculture and the food industry was growing. Their chemical composition creates optimal conditions for microor-ganisms growth. In aerobic and anaerobic fermentation process, bacteria are decomposing in organic compounds. The result of this change is the emission of greenhouse gas (CH4, H2S, CO2, NOx) and nitrogen compounds, phosphorus and potassium. There are various types of fermentation, but one of them, may play a special role in renewable energy sources and waste management. It is a biogas production. Firstly in this process the energy contained in biomass is converted into useful fuel (source of clean, renewable energy). Secondly biogas can be burned in a boiler for heat energy used for heating equipment, or it can be used in the electric generator. This method belongs to organic recycling.This paper presents the analyses and results of biogas production from or-ganic fraction of municipal waste in the process of co-fermentation with the mass of agricultural waste. To illustrate the potential of economic aspects of biogas pro-duction, the study was conducted on six mixes, with different level of the organic fraction selected from municipal solid waste.
