Waste-to-energy (MSW) in depth - U.S. Energy Information

The process of generating electricity in a mass-burn waste-to-energy plant has seven stages: Waste is dumped from garbage trucks into a large pit. A giant claw on a crane grabs waste and dumps it in a combustion chamber. The waste (fuel) is burned, releasing heat. The heat turns water into steam in a boiler.
