GYPSUM DRYWALL RECYCLING

Reuses
Links

Gypsum drywall is the second most common component of the construction waste stream, especially new residential construction. It is made with gypsum that is covered on both sides with a paper facing and paperboard backing. Approximately 12% of new construction drywall is wasted during construction. 

Re-uses for Gypsum Drywall Include:

• Recycling it into new drywall after most of the paper is removed
• Grinding up the drywall and using the gypsum for sewage sludge drying
• Grinding it up and applying it to roadways to counteract the adverse effects of road salt application in the winter
• Using it as a soil amendment for gardens and lawns
• Using it as an odor treatment for animal manure

Grinding equipment can range from a large plant to a small mobile chipper. A hammer-mill is often used to produce a product that is approximately 90% gypsum and 10% shredded paper. Drywall recycling produces dust, therefore a baghouse or air vacuum system may be required to handle the air emissions. This type of equipment can be retrofitted for a particular application or purchased as a package unit.
