 In June 2009 the EPA put out a report that functioned as a road map to SMM in the U.S. titled "Sustainable Materials Management - The Road Ahead 2009 - 2020".In this report, EPA defines SMM as “... an approach to serving human needs by using/reusing resources productively and sustainably throughout their life cycles, generally minimizing the amount of materials involved and all associated environmental impacts”.The Resource Conservation and Recovery Act (RCRA) sets the legislative basis for SSM in the United States, establishing a preference for resource conservation over disposal.In 2010, the Office of Resource Conservation and Recovery shifted focus from just resource recovery efforts to adopt a broader sustainable materials management approach.
