# Why is this an environmentally-sound approach to generating electricity?

The Environmental Protection Agency (EPA) requires all landfills to collect the gas produced by decomposing refuse in order to reduce pollution. Coffin Butte has the option to collect the gas and flare it, but using landfill gas to produce electricity offsets the use of fossil fuels – such as coal – and helps reduce local air pollution. Because Coffin Butte produces power from biomass materials, it is a clean renewable resource.
