Key factors that define an ideal application for landfill gas and factors that are unfavorable to the usage of gas are presented. Waste formate and regulation - is a one principally environmental protection problem. Great quantitys organic waste take away to the dumps. This article analyse processe organic waste destruction and biogas quantity and quality composition. The utilization of biomass to produce energy is one of the most importantant and accessable renewing sources of energy in our country.
