BIOENERGY POTENTIAL OF PIG MANUFACTURE IN THE CONDITIONS OF ANIMAL BREEDING COMPANY IN THE BELGOROD REGION OF RUSSIA
The article presents the results of studies of the biogas potential of pig manure of different sex and age groups obtained from animals of one of the pig breeding complexes of the Belgorod region. The chemical composition of the starting substrates was studied. Pig manure generally showed satisfactory biogas productivity. The specific biogas yield from it ranged from 0.239 ± 0.003 to 0.316 ± 0.003 m3/kg VS, the methane content from 61.3 to 64.0%. The best indicators were observed for manure of piglets and fattening pigs. Given the developed industry of pig farming, the introduction of biogas technologies is a promising option for solving the problem of waste in the region. However, the design of biogas plants should take into account the specifics of local substrates.
