Solid Waste Processing Operations
Operation
Typical Benefits
Source Separation
Reduces mass of waste requiring landfilling
through manual separation of aluminum cans,
steel cans, glass, newspaper, and corrugated
fiber prior to conventional commercial collecti
Size Reduction
Improves compatibility of refuse with other
processing equipment; reduces need for landfill
cover material; improves marketability of
recovered secondary materials.
Air Classification
Concentrates combustible material in the light
fraction; concentrates metals and glass in the
heavy fraction.
Screening
Improves the quality of refuse-derived fuel (RD
and compost; serves to concentrate cardboard an
can stock.
Magnetic Separation
Yields marketable ferrous scrap product; improv
quality of RDF.

Facilitates transportation and storage of RDF;
necessary for stoker firing of RDF.
Baling
Facilitates handling, transport, and storage of
refuse or recovered materials; increases densit
of waste to be landfilled.
