Cofermentation of agricultural waste and by-products

Abstract

The energetic utilisation of the liquid pig manure with other wastes together with by-products significantly
increases the profit-making ability of the agricultural enterprises. The economical operation of the pork
breeding claims the increase of the firm size especially, which may entail the considerable increase of the
environment-damaging effects ARTHURSON, 2009). The many times beneficial application of the biogas
production (energy production + environmental protection investment + biomanure production + the
treatment of hazardous waste and its utilisation) expounds his effect then only, if the possible coferment’s
power generating ability is modelled similar to operating circumstances between conditions on an
experimental road beforehand. I outlined the possible techniques of application being attached to the different
methane content of the biogas in my work. I pretended with the loads changing, the changing of substrat
combinations and the changing of manure production in the course of the experiments. The intensity of the
methane production is the direct measure of the activity of the methanogen bacteria, and than like that, the
most sensitive, typical indicator of the digester’s yield. The combination of the produced gas and its yield
features, that may be useful to estimate the stability of the anaerobic system. Consequently the results of the
examinations bring practical profit on the sizing, investment and firm operational area indispensable.
