Definition of Energy-from-Waste (“EfW”) or Waste-to-Energy (“WtE”)

EfW is a process that takes solid waste and creates energy, typically in the form of electricity, from the combustion of that waste. Waste is transferred into combustion chambers where it is reduced to 10 percent of its original volume. The heat generated within the combustion chambers heats water contained in steel tubes located along the perimeter of the boiler. This hot water turns to steam, which is filtered through a turbine that continuously generates electricity.
