Ferrous Processing
Facility
The Ferrous Processing Facility processes
ferrous metals (such as "tin" cans) recovered at the
Renewable Energy Facility and the landfill.
CFC (freon) containing white goods
recovered from the Class 3 landfill are inspected prior to processing
and any CFC's are removed. The white goods are then crushed by
hydraulic grapples, loaded into trucks, and hauled off-site for further
processing.
The mixed ferrous material from the
Renewable Energy Facility is size-reduced by a vertical shredder, and
passed through an air classification system, which is coupled with
magnets to separate the ferrous material from the non-ferrous tramp
material. The tramp material is returned to the Renewable Energy Facility to be processed into refuse derived fuel and burned
to produce electricity. The
compacted white goods and clean ferrous material are then taken by truck
to a railroad spur at the north end of the SWA property.
The ferrous material is transported by
railcar to manufacturers who melt it down to make new steel products.
The SWA recovers and sells more than 30,000 tons of ferrous metals per
year. The revenues, $1.2 million in 2004, are used to offset
system costs.
