Intensification of pig manure digestion by co-substrate addition in the form of municipal biowaste
Summary.

The article presents the results of a study meant to increase the biogas production generated in mesophilic anaerobic digestion of pig manure. It was attempted to establish the most favourable proportion of municipal biowaste as a co-substrate, which did not impact either the stability of methane fermentation or susceptibility of digested biomass to dewatering in a negative way. It was established that the most appropriate municipal biowaste proportion amounted to 30% of TS, which is about 10% if expressed as wet weight. As compared to the sample containing pig manure exclusively, the biogas production rate for the optimum co-digestion mixture (30% TS of municipal biowaste + 70% TS of pig manure) increased by about 35%. Besides, the process exhibited stable conditions and did not deteriorate significantly susceptibility of digested biomass to dewatering.

Key words: anaerobic digestion, co-digestion, biogas, animal by-products, pig manure, municipal biowaste
