The Federal Pollution Prevention Act of 1990  established policy tools and goals for environmental protection, specifically recommending “pollution should be prevented or reduced at the source whenever feasible..."
The law defines source reduction as any practice that:
Biotechnology and Green Chemistry
Green chemistry  or sustainable chemistry aims to design and produce cost-competitive chemical products and processes that reduce pollution at the source.
Specifically, green chemistry minimizes or eliminates the hazards of chemical feedstocks, reagents, solvents, and products. Additionally, green chemistry prevents waste by using renewable feedstocks, increasing energy efficiency and working in real time to prevent pollution. U.S. EPA recognizes that industrial biotechnology meets these criteria of green chemistry.
Presidential Green Chemistry Challenge
The annual Presidential Green Chemistry Challenge Awards  recognize novel technologies that provide significant environmental and economic benefits through chemical design, manufacture, and use.
EPA presents awards in five categories:
 D. Ahmann, and J. Dorgan. "Bioengineering for Pollution Prevention through Development of Biobased Energy and Materials." 117-29. Washington: National Center for Environmental Research, US Environmental Protection Agency, Office of Research and Development 2007
