Recovery/Destruction Processes C.5.1 - Plastic Flotation Separation - shredded and co-mingled plastics from electronic hardware are segregated by type, i.e., ABS, PSP, PVC, etc. utilizing a flotation process initially developed by Argonne National Lab.  The segregated plastics are sold to manufactures as production feed stock and/or blend. C.5.2 - Melt/Smelting – Aluminum breakage (material that has an aluminum content) is melted in a furnace and poured into a “sow” form.  These “sows” are mill ready grade and are sold to secondary processors who alloy it for a specific use, or sold directly to manufactures as feed stock.  The steel and other metal alloys that is not melted is sold to steel mills and foundries as production feed stock. C.5.3 - Shredding – Low-grade material, such as printed circuit boards are shredded and reduced to metal via an initial bake and then fusion via a pyro-metallurgical process. C.5.4 - Baling- volume reduction via compaction or reduction to smaller pieces via mechanical means. C.5.5 - Precious Metal Recovery -  High-grade component material is processed utilizing a hydro-metallurgical process.  This chemical process produces zero waste as chemicals and waste waters are recovered and reused. C.5.6 - Wire Chopping – Copper and/or aluminum core insulated wire is processed through a machine that chops the wire into small pieces.  These pieces are fed into a de-stoning separator that uses mechanical and pneumatic forces to separate the metal from the insulation.  Both metal and insulation are then segregated and sold. C.5.7 - Electrowinning – is a unique reverse plating process that allows a high recovery percentage of precious metals, as opposed to various other methodologies. C.5.8 - Grinding/Deburring of Glass – Lead glass from cathode ray tubes are initially size reduced to return maximum revenue for the lowest processing cost.  The leaded glass is then sold to cathode ray tube manufactures.  The non-leaded glass is size reduced, deburred of sharp edges and used as granular material substitute in production processes, i.e. retaining wall brick. C.5.9 - Eddy Current Separation  - Material separation normally after shredding utilizing electric, magnetic and gravitational forces to sort materials into like categories.
