The Use of Agricultural Biomass as a Source for Biogas Production

Abstract

As raw materials in bioenergy can be used agricultural residues formed in the process of harvesting crops and the process of their processing, in particular straw cereals, legumes, corn and sunflower seeds, etc. For energy needs, agricultural biomass is used by burning or processing into solid, liquid, or gaseous fuels. In the production of gaseous fuel in special plants - bioreactors, agricultural waste is formed not only as a source of energy - biogas, but also as excellent fertilizers. In this article, studies have shown that the amount of biogas produced depends on the type of biomass and fermentation time. The largest amount of biogas is produced within 10 days from the date of loading of organic biomass. It was found that the highest daily biogas production is formed from grass and grain silage, the maximum value of which is 1.76 m3. The smallest - from rapeseed silage – 0.33 m3.
