ABSTRACT
On large-scale animal breeding farms in Hungary a large amount of slurry is produced, its disposal is problematic on account of the hazard on environmental pollution. Governmental decisions were made to establish biogas plants with central subsidy for processing a part of the slurry and other wastage of organic origin, such as communal wastage. Following this governmental programme two large-scale biogas plants were constructed and in this paper we would like to give a review about the results of our investigations.
At one of the biogas plants the appr. daily amount of 60 m3 slurry coming from a dairy farm with 750 cows is processed in continuous operation by the technology based on the Austrian BIMA licence. The other plant operating periodically produces biogas in digesters of 650 cb.m volume by digesting mainly cattle litter and manure, and other communal wastage, sewage, etc.
