INVESTIGATION OF METHANE EMISSION DURING DECOMPOSITION OF ORGANIC WASTE

The article deals with the current state of municipal solid waste (MSW) management in Ukraine. Most of the waste buried in landfills and dumps. MSW landfills in the country occupy a large area, the leachate which produced in landfills can contaminate groundwater and harmful gases cause air pollution and contribute to the greenhouse effect. The gas which is formed during the decomposition of organic waste in landfills called landfill gas whose main ingredient is methane. Methane is formed in four steps and requires certain conditions, such as temperature, composition of the waste, etc. An experiment on the formation of biogas from four waste mixtures was conducted and dependences of landfill gas production on waste composition were built. Also an experiment of landfill gas production with a mixture of proteins and fats mixture in different temperature regimes with and without stirring the mixture was conducted.
