Results of verification of the slaughter waste anaerobic fermentation process

Results of verifi cation of the slaughter waste anaerobic fermentation process. The article deals with the analysis of results of verifi cation of a one-stage anaerobic digestion at mesophile and thermophile conditions in two series differing in retention time (26 and 37 days). Substrates consisting of various proportions of poultry crushed bones, pork ligaments, and slurry of beefcattle and pigs (1:1) were used. Stabilized nondrained remainder of an anaerobic digestion was used as inoculum. Results of verifi cation showed effectiveness of slaughter waste processing in biogas stations. However, slaughter waste processing requires installation of equipment for a thermal modifi cation of the feed-in substrate (warming up to 70°C for the duration of 1 hour).
