Plastics and Process Engineered Fuel (PEF): an Overview
Scrap plastics and paper can be made into process engineered fuel (PEF) for co-firing in existing solid fuel boilers. PEF systems offer the opportunity to divert significant amounts of materials from disposal while also conserving fossil fuel resources. PEF is a manufactured product produced in either shredded (fluff) or densified form and has predictable combustion characteristics. PEF prices, fuel characteristics, and resulting air emissions can be attractive in comparison to other more conventional fuels. Plastics enhance the energy content of these fuels. The economics of PEF systems are very case specific, and can be favorable under certain conditions.
