Co-fermentation of agricultural organic waste, main and by-products

Absztrakt

My research work proposes the study of the impact of the biogas production by co-fermentation of agricultural products. The basic substance is the dangerous liquid pig manure of the concentrated stock of big pig farms. The utilization of these materials as an energy source spells large income for the agricultural enterprises, saving the replacement of plant nutrition utilization of bio-manure, to increase the performance of the plant production, making harmless the dung which means a big environmental load. Because of the profitability of bioenergy utilization depends on the local conditions it is necessary to do experiments to try the available composition of organic wastes in the ratio of the production in advance. We measured the quantity and the methane and CO₂ content of the biogas released from the substrate. The experiment simulated real biogas plant conditions, in mesophile temperature, in continuous biodegradation process. It can be considered, as a semi-industrial size.
