Landfill gas
Even controlled landfills emit methane, a flammable gas which is also a potent greenhouse gas. This can be collected and used to fuel a gas engine or gas turbine. Typical capacities are 0.5 to 10 MW of electrical output – displacing that amount of generation from less environmentally-friendly sources.
Darley & Associates have considerable expertise in the design of gas gathering, gas cleaning and compression, and power generation from existing and new landfill sites.
