Abstract
The article studies technical possibilities of co-digestion of various types of organic waste in order to increase biogas yield and to solve the problem of efficient disposal of faecal sludge. The objects of study were: faecal sludge from a septic tank, sewage sludge from wastewater treatment plant, cattle manure and poultry manure from a livestock farm. Technological features and determination of optimal operating parameters of organic waste anaerobic digestion were investigated. Priority composition of organic waste mixture for anaerobic digestion that provide the maximum biogas yield, as well as the ratio of nitrogen and phosphorus in the digestate was determined.
