Evolving Wallboard RecyclingClosed Loop Pilot Project Presented by: Amanda Kaminsky, Founding Partner, Building Product EcosystemsTerry L. Weaver, President, USA Gypsum
Gypsum Wallboard Recycling
1996 U.S. start upsClose loop Fail. “upcycling”required
20 Years!
USA Gypsum 1998 – 4,000 Sq. Ft. 2,000 Tons per Year
U.S Policy Impact
Clean Air Act Requires SO2 Reductions Synthetic Gypsum Floods Market 2005-
2012 Recession Shrinks Demand Cheap Natural Gas
More Air Regulations Less Coal Burned = Less Gypsum Clean Air = Farmers Purchase Sulfur

Recycling Growth Barriers?Mining A Resource From Construction Waste
New USA Gypsum Drywall Recycle Plant – 100,000 Ton Capacity
New York City Generates 165,000* ton Year *Source NYS DEC, 2010
Multiple Attempts to Recycle – Limited Success
Policy efforts since 2003 Audit Recycling Rates Durst Initiates Building
Product Ecosystems Evolving Wallboard
Systems Work Group Established
One World Trade Center
One Bryant Park
Driver: Transparent Lifecycle + Content Accountability
Driver: Drywall Numbers in the U.S. ~9 million tons drywall waste generated/year ~400,000 tons recycled/year Millions of tons being landfilled each year
Driver: Availability of Synthetic Gypsum/Coal Byproduct
Driver: Comingled Packer Truck Loads = Mixed Fines
