The Environmental Protection Agency (EPA) today is amending the Comprehensive Procurement Guideline (CPG) by designating seven new items that are or can be made with recovered materials, including: modular threshold ramps; nonpressure pipe; roofing materials; office furniture; rebuilt vehicular parts; bike racks; and blasting grit. In addition, EPA is revising the designations for three items, including cement and concrete, railroad grade crossing surfaces, and polyester carpet. For cement and concrete, EPA is adding cenospheres and silica fume as recovered material options. For railroad grade crossing surfaces, EPA is adding recovered wood and plastic as recommended recovered materials. For polyester carpet, EPA is revising its designation to designate polyester carpet for moderate end-uses only, as defined by the Carpet and Rug Institute. The CPG implements portions of the Resource Conservation and Recovery Act (RCRA) and the Executive Order "Greening the Government Through Waste Prevention, Recycling, and Federal Acquisition," which require EPA to designate items that are or can be made with recovered materials and to recommend practices that procuring agencies can use to procure such designated items. Once EPA designates an item, any procuring agency that uses appropriated federal funds to procure that item must purchase the item containing the highest percentage of recovered materials practicable. Today's action will use government purchasing power to stimulate the use of these materials in the manufacture of products, thereby fostering markets for materials recovered from solid waste.
