[0] 8 [Description] The specification for the EPA facility included detailed requirements for minimum recycled content by material type. The EPA’s Recovered Materials Advisory Notices (RMAN) provided preliminary guidance. Research into market availability was then performed using a detailed questionnaire. The goal was to evaluate the cross-section of products available so that a competitive range of manufacturers could be selected. Products specified with recycled content include rubber flooring, ceramic tiles, asphalt paving, cast-in-place concrete, insulation, wood fiberboard, gypsum wallboard, and more. The following list presents all of the recycled content provisions in the final specification. The list represents minimums and many materials were procured that contain more than the minimum required. Product Required Recycled Content Asphaltic concrete paving 25% by weight Reinforcing steel in concrete 60% recycled scrap steel Reinforcing bars in precast concrete 60% recycled steel Concrete masonry unit 50% recycled content Reinforcing bars in concrete unit masonry 60% recycled steel Framing steel 30% recycled steel Fiberglass batt insulation 20% recycled glass cullet Fiberglass board insulation 20% recycled glass cullet Mineral wool insulation 75% recycled material Mineral wool fire safing insulation 75% recycled mat’l by wt Gypsum board 10% recycled or synth gyp Facing paper of gypsum board 100% recycled newsprint including post consumer Mineral fiber sound attenuation blankets 75% recovered mat’l by wt Steel studs, runners, channels 60% recycled steel Acoustic panel ceilings 60% recycled mat’l by wt Ceiling suspension systems 60% recycled material Rubber floor tiles 90-100% recycled material Hydromulch 100% recovered materials Structural fiberboard 80-100% recycled content For more details about this technology/strategy and project, including photos, a video, detailed documents, and specifications, see http://www.epa.gov/rtp/new-bldg/environmental/environmental.htm [Technology]
