Beneficial Reuse of New Construction Scrap Gypsum Drywall

The Problem Excessive Volume 1 Pound of Scrap Gypsum Drywall is Generated for Every Square Foot of Floor Area in a New House A 2, 000 Square Foot House = 1 Ton of Waste Gypsum Drywall! A Year’s Worth of New Construction = Over 8 Billion Pounds of Drywall Scrap Annually in the U. S. A.

Hazardous Decomposition Under Certain Landfill Conditions Anaerobic Decomposition of Waste Gypsum Drywall Produces Toxic Hydrogen Sulfide Gases also Excessively Wet Landfill Conditions may Produce Toxic Hydrogen Sulfates Threatening Groundwater Resources Environmental Time Bomb Numerous Landfills Today Now Emit These Toxic Pollutants due to Decades of Gypsum Drywall Disposal

A Brighter Future Halting the Flow of Gypsum Drywall Scrap to Landfills Yields Immediate Results ØLandfill Space is Preserved ØHydrogen Sulfide/Sulfate Production is COMPLETELY Eliminated

Waste Stream Diversion Diverting Scrap Gypsum Drywall from Landfill Disposal Produces: Immediate Benefits ØMakes More Landfill Space Available ØDefuses Potential Environmental TIME BOMB ØCreates Beneficial Gypsum-Based Products

Reclamation is the Answer Not Recycling Transportation Costs for Scrap Gypsum Drywall Back to Factories is Prohibitive Alternative Reuses ØAgricultural Gypsum ØAnimal Bedding and Odor Control

ØMoisture Control ØPond Clarification ØLandfill Capping ØReclamation of Sodic Soils ØGypsum improves soil structure ØGypsum prevents crusting of soil and aids seed emergence ØGypsum improves low-solute irrigation water
