Waste is unwanted materials that are mainly the result of human activities and one of the sources of environmental pollution. An increase in the world’s population causes a growth in the amounts of waste in the modern world. Every year, the increasing quantities of waste are the major problems these days; therefore, calls for taking effective measures to tackle this problem could be effective tools. The article presents the results of experimental studies on using meat waste and their mixes with herbal waste. The conducted experiments observed the concentrations of methane, hydrogen sulphide and oxygen under periodic mesophilic conditions in the bioreactor. Research has shown that the use of herbal supplements with meat waste produces better results than using only meat waste. The digestion of meat wastes points to an average amount of biogas which is 0.5 m3/m3d, that of meat and herbal waste mixture (19:1) – 0.51 m3/m3d, meat and herbal waste mixture (9:1) – 0.56 m3/m3d. The content of biogas methane was 0.074 m3/m3d, 0.083 m3/m3d, 0.101 m3/m3d respectively.
