Features of the processing of liquid slaughterhouse waste into biogas

Miroshnichenko Irina Vladimirovnа

Recently, in connection with the development of alternative energy, livestock waste and processing companies are increasingly being considered as co-substrates for biogas stations. Slaughterhouse waste has a high potential and, in selecting the optimal processing technology, can cover a significant proportion of production costs. Despite this, when bioconversion into biogas, they can create technological difficulties: their high protein content leads to a high load of ammonium nitrogen, to which the microflora of the bioreactor must be resistant. In this paper, the authors conducted a study of sludge flotation sludge slaughtering and processing of pigs. Based on this study, the results and conclusions are presented.
