Abstract: Studies have been carried out with sewage sludge samples from Kaunas, Raseiniai and Anyksciai wastewater treatment plants as well as meat bone-meal from Rietavas Veterinary Sanitation plant. Biogas volume yield from the processed biomass unit has been measured, and biogas composition has been determined. Substrate quality before and after anaerobic processing has been evaluated according to its agrochemical properties and heavy metal content. Sustrate recycling possibilities in the form of biofertilisers has been studied. Data showed, that the highest biogas yield was in the case of Kaunas sewage sludge, with meat-bone meal additive or without, whereas the highest methane concentration in biogas was determined after Raseiniai sewage sludge anaerobic treatment. The lowest heavy metal concentration, but the highest content of biogenic elements and organic matter was found in anaerobically processed Raseiniai sludge substrate. Meanwhile Kaunas substrate had the lowest agrochemical value
