Industrial Materials Recycling Team • Promotes the reduction, reuse, and recycling of industrial materials • Construction and demolition (C&D) materials • Coal combustion products (CCPs) • Foundry sands • Tires • Slags • Pulp and paper residuals
Why reuse/recycle these materials? • They • Can substitute virgin materials AND save energy, time, and money • Perform as well or better than virgin materials • Capture valuable materials that would otherwise be lost. • Recycling/reusing can mean points for green building certification.
Components of C&D Waste • Wood • Engineered Wood • Oriented Strand Board (OSW) • Plywood • Blackboard • Dimensional Lumber • Treated Wood
Wood Markets: • Boiler Fuel • Mulch • Engineered boards
Portland Cement Concrete Markets: • Road Base • Aggregate
Asphalt Concrete • Heavily Recycled in New Hot Mix Asphalt
Components of C&D Materials • Gypsum Drywall • Markets: • New Drywall • Portland Cement Production • Agriculture • Construction Material
Components of C&D Materials • Roofing Materials • Asphalt Roofing Shingles • Asphalt Roofing Felt • Recycled into new hot mix asphalt.
Components of C&D Materials • Metals • Ferrous • Nonferrous • Aluminum • Copper
Components of C&D Materials • Paper Products • Cardboard
Consigli’s Waste Management Four Tier System • Tier I: Direct Reuse and Recycling • Tier II: Source Separated Materials • Tier III: Mixed C&D to Offsite Separation • Tier IV: Mixed C&D to Landfills
State Programs & Regulations • Massachusetts ban on disposal before processing • California requires 50% diversion from landfills • Various states have grants and education programs
Local Ordinances • Disposal bans • Ban of specific materials from being disposed • Waste plan requirement • Require all contractors to submit plans on how they will reduce disposal when applying for a permit • Deposit system • Fee required when applying for a permit that is returned when recycling is proven • Salvage period requirements
Other Factors Influencing Recycling • Increases in fuel prices • Green building initiatives • Efforts to reduce GHG emissions • General difficulty to site landfills
Not Just C&D Materials … Remember: It is important to reuse/recycle the waste your company generates, but It is also important to use recyclable materials from other industries in construction design.

Industrial Materials Recycling Team • Measure – “What gets tracked gets managed” • Explore barriers and how to overcome them • Increase awareness • Recognize success
Measurement: C&D Materials Preliminary 2003 draft numbers • Will be measuring annually -- need a viable, economically feasible source of data • Currently looking at data states collect and publish
Exploring Barriers, Increasing Awareness • Construction Initiative • Encouraging use of industrial materials in building or highway construction projects • Green Buildings, Highways, and Sustainable Sites • Helping develop criteria • Promoting industrial materials recycling in green structures/sites • Promoting coordination between transportation and environmental agencies
Exploring Barriers, Increasing Awareness • Asphalt Shingle Recycling Forums • Foundry Sand Forum • Beneficial Use Summit
EPA’s Innovative Grants • 2005 Grant to CMRA for Tear-Off Asphalt Shingles Recycling • Update www.shinglerecycling.org website • Recycling Asphalt Shingles: Best Practices Guide • Environmental Issues Associated with Asphalt Shingle Recycling

EPA’s Partnership with AGC • White paper • Demonstrate a support for reduction, reuse, and recycling • Reuse and recycling should be performed in a safe manner
EPA’s Partnership with AGC • Measurement tool for contractors How much did my company reused/recycled? How much did my company SAVE?
EPA’s Partnership with AGC • Recognition • Case Studies • Others?
Things to Think About • What obstacles have you encountered? • What role does each participant play in overcoming the obstacles to industrial materials recycling? • Contractors • Manufacturers • States • EPA
Things to Think About • What tools and resources do contractors need to • Reuse/recycle materials • Use recycled materials
Case Studies • Recycling/reusing C&D materials • Using industrial materials • Need: • Amount and types of materials that were reused/recycled • Size of project • Amount of money saved (if available) • Obstacles encountered and how they were overcome
