Drywall makes up 13% of construction, renovation & demolition waste.
Drywall is made of a sheet of gypsum, covered by a paper facing and a paperboard backing and various additives to decrease mildew, increase fire resistance, and lower water absorption.The Gypsum is also used as a fertilizer.
On average up to 12 percent of Drywall becomes waste during manufacturing and when when being installed. This makes a big contribution to the materials that end up in landfills and increasing landfills are starting to no longer accept drywall.
The ideal solution for gypsum material is a closed-loop re-utilization of the material, in which recycled material is returned to the wallboard manufacturer to be used to make new drywall. Gypsum can essentially be recycled forever with no degradation to the material, to reduce the volume of new material that is needed.
