Mechanical–biological pretreatment of municipal solid waste (MSW) can significantly improve the behaviour of landfills. Chemical oxygen demand (COD) and total nitrogen in the leachate, as well as the gas production rate, are about 90% lower than for untreated waste. The volume to be landfilled decreases by mechanical–biological pretreatment by up to 60%.
