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
