Materials separation in solid wastes streams will generate more BTU's at waste-to-energy facilities. The removal of noncombustibles like bottles, batteries and refrigerators more than offset the removal of combustibles like newspapers. With an expected growth in the number of waste to energy facilities, the new upping BTU data may be the economic kicker that materials separation has always lacked. Because curbside programs have shown, at best, a 25% reduction of solid waste, it may be necessary to separate an entire waste stream when it arrives at the incinerator. Various waste processing systems are discussed, including a facility in Nashville that automatically removes aluminum cans.
