The Federal Government is the largest single purchaser of construction in the United States. The study examines the feasibility of the Government's using this considerable purchasing power to require the use of secondary materials in construction products as a means of increasing recycling. The analysis of Federal construction procurement policies, laws, regulations, and funding levels shows that while the Government is a major purchaser of construction materials, there are significant constraints to requiring recycled materials in these products. An in-depth technical and economic analysis of opportunities to use secondary materials recovered from the municipal solid waste stream shows that Federal construction procurement could impact significantly on the materials in the municipal solid waste stream.
