The IWSA is a national trade organization representing the waste-to-energy industry and communities that own waste-to-energy facilities. Current IWSA members own and operate 69 of the 87 modern waste-to-energy facilities that operate nationwide, safely disposing of municipal solid waste, while at the same time generating renewable electricity using modern combustion technology equipped with state-of-the-art pollution control systems. These facilities have been recognized by EPA as a “clean, reliable, renewable source of energy” that produce “electricity with less environmental impact than almost any other source of electricity.” IWSA members include Covanta Energy Corporation, Veolia ES Waste-to-Energy, Inc., and Wheelabrator Technologies Inc., as well as 26 municipalities that are served by waste-to-energy plants and other associate members that work in the municipal waste management and energy fields.
