The research was carried out while feeding the digester with 373,4 g of salmon waste and cow manure and 94,7 g of salmon waste and maize silage. The organic volumetric load was kept at 2 kg/m3d. Research results: biogas yield from 1 kg of cow manure mixed with salmon waste was 700,2 l/kg of dry matter and 836,9 l/kg of dry organic matter. The concentration of methane in biogas produced from maize silage and salmon waste mixture was 69,9 %, while methane concentration from cow manure and salmon waste was 64,4 %. The energy potential from maize silage and salmon waste mixture was by 14 % higher than the salmon waste and cow manure dry matter.
