The effect of substrate on the amount and composition of biogas in agricultural biogas plant

Construction of biogas plants processing agricultural waste enables to reduce waste, limit emission of gases and odors in rural areas as well as gives the possibility to ensure self-sufficiency of energy. The amount of generated electricity and heat depends on the quantity and quality of biogas. The aim of this work was to show how the substrate affects the amount and composition of the biogas in agricultural biogas plants. The most commonly applied types of substrates in agricultural biogas plants in 2011-2012 and in the first half of 2013 were indicated due to the Agricultural Market Agency data. The research also showed the amount of agricultural biogas produced as well as the amount of electricity and heat generated from agricultural biogas during the time period mentioned above. ...

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. ...
