The Gypsum Recycling Process
New West Gypsum Recycling receives pre- and post-consumer gypsum waste, reconstitutes the materials into useful products, and provides the raw material for new manufacturing.
Waste wallboard and gypsum goes through the following general processing stages in the NWGR process:
- Inbound wet and dry loads of waste product are dumped on the NWGR plant's tipping floor, and hand-cleaned of metal, plastic and other debris.
- The raw material gypsum waste is loaded into a large feed hopper and then fed onto a conveyor belt, where an electromagnet removes ferrous metal fragments.
- The material is then conveyed to an enclosed processing area that separates the paper liner from the gypsum core.
- The recyclable gypsum is trucked back to drywall manufacturers, where it is combined with virgin rock or synthetic gypsum to make new wallboard. NWGR studies have shown that new wallboard can include in excess of 25 percent recycled gypsum. Also, recycled gypsum combined with synthetic gypsum produces desirable consistency levels in the manufacture of new gypsum-based products.
- The paper is further processed prior to recycling for use in a wide variety of applications.
Minimal local environmental impact of the NWGR recycling plant
NWGR has developed on-site wheel wash and air filtration systems to reduce the local environmental impact of the recycling plant.
