Petroleum products- We derive a majority of our revenues from the sale of recovered/re-refined petroleum products, which include Base Oil, VGO (Vacuum Gas Oil), Pygas, Gasoline, Cutterstock and Fuel Oils.

Metals- Consist of recoverable ferrous and non-ferrous recyclable metals from manufacturing and consumption.  Scrap metal can be recovered from pipes, barges, boats, building supplies, surplus equipment, tanks, and other items consisting of metal composition.  These materials are segregated, processed, cut-up and sent back to a steel mill for re-purposing.
