During the decomposition of waste as a result of the vital activity of various microorganisms, landfill gas is formed, containing about 140 toxic chemical compounds. The basis of landfill gas is methane (40-75%) and carbon dioxide (25-45%). Also when rotting
protein products, hydrogen sulfide is released (it has a characteristic smell of rotten eggs).
