5 Green SITES vs. Green BUILDINGS Green building activities have already pushed C&D materials recycling and use of recycled-content materials Sustainable Sites will be adopted by USGBC for integration into their LEED Standards Current LEED Standards focus on the BUILDINGS primarily Sustainable Sites will help direct more focus on the SITE

6 Factors Influencing Recycling New regulations/ordinances requiring a percentage recycled Increases in fuel prices Green building initiatives Efforts to reduce GHG emissions General difficulty to site landfills

7 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 Green purchasing programs for government Green building requirements for government

8 New Executive Order Strengthening Federal Environmental, Energy, and Transportation Management the head of each agency shall ensure that (i) new construction and major renovation of agency buildings comply with the Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings set forth in the Federal Leadership in High Performance and Sustainable Buildings Memorandum of Understanding (2006) Recycled Content. For EPA-designated products, use products meeting or exceeding EPA s recycled content recommendations. For other products, use materials with recycled content such that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (based on cost) of the total value of the materials in the project. Construction Waste. During a project s planning stage, identify local recycling and salvage operations that could process site related waste. Program the design to recycle or salvage at least 50 percent construction, demolition and land clearing waste, excluding soil, where markets or on-site recycling opportunities exist.

9 Why reuse/recycle these materials? They Can substitute virgin materials AND save energy, time, and money Reuse/Recycling can mean a reduction in greenhouse gas emissions 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.

10 Implications for Reuse/Recycling Sustainable Site standards will promote The reduction, reuse, and recycling of materials produced on site The use of these materials in onsite applications Materials use locally where no reuse/recycling opportunities exist onsite Use of reusable/recycled materials produced locally

11 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

25 Other Waste Components Land clearing debris Stumps Vegetation Rocks Soil Hazardous or dangerous components Need to be managed appropriately if found onsite Eliminate purchasing of these materials for future construction

26 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

27 EPA s Partners for Recycling Industrial Materials Federal Highway Administration Associated General Contractors of America Building Materials Reuse Association Construction Materials Recycling Association National Association of Home Builders National Demolition Association Association of State and Territorial Solid Waste Management Officials American Public Works Association National Association of Counties Foundry Sand Recycling Starts Today American Coal Ash Association Rubber Manufacturers Association National Council for Air and Stream Improvement National Slag and Slag Cement Association Recycled Materials Resource Center

28 Example Materials Found OFFSITE used ONSITE Materials: Foundry Sands Coal combustion products Fly ash FGD gypsum Recycled concrete & asphalt pavement Recycled asphalt shingles Recycled wood Recycled drywall Slags Pulp and paper sludges Used As/In: Fill Road materials Mortars Building materials Soil amendment Mulch/compost New pavement
