Утилизация биогаза полигонов твердых бытовых отходов

The analysis of the state of the issue of biogas utilization of municipal solid waste landfills both in world practice and in Ukraine has been carried out. The forecast for methane production at landfills for municipal solid waste is given. The reduction of greenhouse gas emissions ware estimated. A biogas utilization system have been developed. It was found that depending on local conditions, the rate of pumping landfill gas from one well is from 5-50 m3 /h to 250 m3 /h. The radius of influence of the well for pumping landfill gas varies within 8-80 m with an average value of 30-35 m. the Distance between the wells should not be less than twice the radius of influence. The developed safety criteria allow to prevent methane explosions in the process of biogas utilization.
