Recycling Gypsum Wallboard

  1. 1. Evolving Wallboard Recycling Closed Loop Pilot Project Presented by: Amanda Kaminsky, Founding Partner, Building Product Ecosystems Terry L. Weaver, President, USA Gypsum
  2. 2. Gypsum Wallboard Recycling  1996 U.S. start ups  Close loop Fail.  “upcycling”required 20 Years! USA Gypsum 1998 – 4,000 Sq. Ft. 2,000 Tons per Year
  3. 3. 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 Gypsum Transport

  6. 6. Pre Sort Is Being Done Successfully New England Recycling, Taunton, MA
  7. 7.  Gypsum Market  Owner Driven Changes  Educating construction industry  Changes in Waste Management Recycling Growth Barriers? Mining A Resource From Construction Waste New USA Gypsum Drywall Recycle Plant – 100,000 Ton Capacity
  8. 8. 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
  9. 9. Driver: Transparent Lifecycle + Content Accountability
  10. 10. 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
  11. 11. Driver: Availability of Synthetic Gypsum/Coal Byproduct
  12. 12. Driver: Comingled Packer Truck Loads = Mixed Fines
