WE MAKE DRYWALL
Hydrous Calcium Sulfate, commonly known as Gypsum, is a non-metallic mineral found in natural rock deposits across the world. Gypsum has a wide variety of uses, but primarily it is known as the main ingredient in drywall (i.e. wallboard, plasterboard, sheetrock). One beautiful attribute of Gypsum is it's eternally recyclable. It can be reused into new drywall over and over again, forever.
Ending Up in Landfills
Despite the fact that gypsum is forever recyclable, drywall waste predominately ends up in landfills. In the United States alone, nearly 15 million tons of drywall ends up in landfills every year, where it takes up limited landfill space, leaches sulfate, and generates hydrogen sulfide, responsible for a noxious odor similar to rotten eggs.
We Have A Better Way
At Scott Equipment Company, our Recycling Products Division developed the GypStream to disrupt this wasteful pattern of sending drywall to the landfill. GypStream makes drywall recycling viable by efficiently separating the gypsum from its paper backing, resulting in pure, clean gypsum that can be recycled for use in a variety of downstream markets or back upstream into new drywall.
A NEW GYPSUM LIFECYCLE
Natural gypsum is mined from rock deposits.
Manufacturers produce new sheets of drywall from calcined gypsum.
Drywall is transported to job sites.
Nearly 10% of drywall used on new construction ends up as cut-off scrap.
Drywall from demolition is typically commingled with other C&D debris, making it difficult to recycle.
Haulers collect drywall and other C&D debris from the job site.
Haulers deliver drywall to the landfill for a tip fee.
Once in the landfill, drywall creates hydrogen sulfide, which has a noxious rotten egg smell.
Gypsum is used as a soil additive for treating sodic and saline soils and is a source of vital nutrients for plants.
Gypsum is used as a compost additive, improving aeration and providing a source of nutrients.
Gypsum is a key ingredient in Portland Cement to aid in the setting time.
Gypsum is effective at absorbing moisture and ammonia in animal bedding.
We can close the loop on the drywall lifecycle by introducing recycled gypsum back into new drywall.
The GypStream Drywall Separator turns scrap drywall into pure, clean gypsum.
Synthetic gypsum (FGD) is produced by scrubbing the gases emitted from coal power plants.
Turning Waste into Value
Nearly 10% of drywall used in new construction ends up as cut-off scraps.
Drywall from demolition is commingled with other C&D debris, making it difficult to recycle.
Drywall and other C&D debris is collected from the job site by a hauler.
