The aim of the work was to compare composting technology and anaerobic digestion in the case of manure from dairy cows. The research was carried on the case study farm in Wielkopolska Region (Western Poland) specialized in milk production (600 cows). The results have shown that both analyzed scenarios can give the additional profits to a studied dairy farm. However, the anaerobic digestion can
