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

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 ...

Quantitative and qualitative analysis of biogas emitted from batches composed on the basis of available factions on the farm

Agricultural Biogas is a fuel gas obtained in the process of methane fermentation of agri-cultural by-products , residues in food processing and animal manure. The aim of the study was to determine the amount of biogas produced from organic masses derived from the farm and to analyze the chemical composition of the resulting biogas. Four available starting materials were subjected to a moisture content analysis and fragmentation. They made ripples that are on the bench and accepted a retention time of 30 days. The paper presents the results of the quantity and quality of the resulting biogas. Delay observed in each fermentation fermenter . The batch of beet pulp has the highest yield of biogas at 66%. The study showed that analyzed the organic mass can be successfully used as a substrate for biogas plant. ...

Determination of the energy potential of biogas in selected farm household

The production of biogas in Poland each year is increasing its share in renewable energy in the country, it is n excellent method of waste disposal as well. Biogas produced in the process of methane fermentation is used to produce electricity and heat. Determining the amount of biogas produced as a result of methane fermentation of available biomas generated from a selected farm household. This research disseratation was written on the basis of the available literature concerning the production of biogas and renewable energy sources the research methodology was based on the German standard DIN 38414. Using the available materials and research studies, a 350 kW piston generator was chosen; the total energy possible to be generated is approx 2806 MWh. As is clear from the foregoing, farm household under study can engage in the production of biogas,, which will provide addi-tional income for farmers. ...
