  1. Construction & DemolitionMaterials William Turley Executive Director, CMRA Associate Publisher, Editor, C&D World

  2. How Much C&D Is Out There? • Original 1997 EPA Estimate of Building-Related C&D Was 136 Million Tons • Left Out Road and Bridge • Latest EPA Estimate is 160 Million Tons • CMRA Estimates 350 Million Tons Annually • Cochran/Townsend say 600 million plus

  3. How Much C&D Is Recycled? • GOK • CMRA Survey Showed 140 Million Tons of Concrete • CMRA/PCA Survey • USGS • Asphalt 150 million tons • 28 Million Tons of Mixed C&D

  4. How Is It Recycled?

  5. Markets • Concrete/Asphalt • Gypsum • Asphalt Shingles • Wood • Metals • OCC • Plastics • Ceiling Tile

  6. Concrete

  7. Uses For Recycled Concrete • Roadbase • Unbound Fill • Erosion Control • Aggregate for Asphalt Mixtures • Aggregate for Concrete Mixtures • Normal Aggregate Uses

  8. www.concreterecycling.org

  9. Barriers To Use • Constituent Questions • Economics • Stubbornness • 140 Million Tons Annually

  10. Gypsum Drywall

  11. Uses For Recycled Drywall • Land Application • Beneficial or Benign Use • Regional • Compost • New Wallboard • Portland Cement • Animal Bedding • Onsite Grinding

  12. www.drywallrecycling.org

  13. Barriers To Use • Economics • Plentiful • Regulator Reluctance • Contaminants • Difficult Material To Recycle

  14. Asphalt Shingles

  15. Uses For Recycled Shingles • Hot Mix Asphalt • Cold Patch • Dust Control On Rural Roads • Temporary Roads Or Driveways • Aggregate Road Base • New Shingles • Fuel

  16. www.shinglerecycling.org

  17. Barriers To Use • Questions On Contaminants • Asbestos, PAHs • Regulator Reluctance/Overkill • Difficult Material To Process • Economics Can Be Very Favorable

  18. C&D Wood

  19. Uses For Recycled Wood • Fuel/Life Cycle Analysis • Mulch (onsite) • Compost/Animal Bedding • MDF/OSB • Large Volume of Material

  20. Wood Recycling

  21. Barriers To Use • Lack Of Value-Added Outlets • Regional Markets • Regulations and Legislation • Contaminants • GHG, Stack Emissions

  22. Carbon Neutral Fuel • C&D derived biomass as a fuel and alternative energy source is recommended because wood is carbon neutral • Wood, as a biogenic source of carbon takes in carbon dioxide during its growth, making it a carbon neutral energy source when combusted • For greenhouse gas counting purposes, the carbon dioxide emissions from wood are not counted (as compared with non biogenic sources such as fossil fuels)

  23. Pro-Recycling Regulations • Massachusetts Disposal Ban • California AB 939 • B.C. Gypsum Landfill Ban • Permitting Crusher, Not Site • Chicago Ordinance • San Jose SCCD Program • Use Recycled Incentives

  24. Anti-Recycling Regulations • New Hampshire C&D Wood Fuel Ban • New Jersey Soil Cleanliness Requirements • Paint on Concrete--Washington, Missouri • Flow Control/Franchises

  25. Trends • Tighter Regulations and Permitting, Including Required C&D Programs • Construction Waste Management/LEED • Green Highways Program • Market Development—Wood, Shingles

  26. CMRA P.O. Box 122 Eola, IL 60519 630/585-7530 www.cdrecycling.org
