Sustainable Materials Management is a systemic approach to using and reusing materials more productively over their entire lifecycles. It represents a change in how a society thinks about the use of natural resources and environmental protection. By looking at a product's entire lifecycle new opportunities can be found to reduce environmental impacts, conserve resources, and reduce costs.

U.S. and global consumption of materials increased rapidly during the last century. According to the Annex to the G7 Leaders’ June 8, 2015 Declaration, global raw material use rose during the 20th century at about twice the rate of population growth. For every 1 percent increase in gross domestic product, raw material use has risen by 0.4 percent.

This increasing consumption has come at a cost to the environment, including habitat destruction, biodiversity loss, overly stressed fisheries and desertification. Materials management is also associated with an estimated 42 percent of total U.S. greenhouse gas emissions. Failure to find more productive and sustainable ways to extract, use and manage materials, and change the relationship between material consumption and growth, has grave implications for our economy and society.

Sustainable Materials Management (SMM) represents a framework to sustainably manage materials and products throughout the entire lifecycle, from resource extraction, design and manufacturing, resource productivity, consumption and end-of-life management.

Traditional patterns of material consumption in the United States follow a Cradle-to-Grave pattern of raw material extraction, product manufacturing, distribution to consumers, use by consumers, and disposal; coined by The Story of Stuff author Annie Leonard as the "take-make-waste" linear economy and commonly referred to as the throw-away society, these familiar waste management practices are being revised to bring about sustainable management of resources. SMM represents a shift in how materials are used and valued with a focus on the environmental impact of material use and environmental protection throughout the entire lifecycle of a product. SMM has been adopted as a regulatory approach to manage materials by the U.S. Environmental Protection Agency (EPA) and many other governments around the world.

Sustainable Materials Management is a broad approach that overlaps and supplements many programs and concepts being adopted by governments and business around the world including zero waste, green chemistry, eco-labeling, sustainable supply-chain management, lean manufacturing, green procurement, the US EPA’s Design for the Environment Program, the G8’s 3R’s (reduce, reuse, recycle) program, UNEP's Sustainable Production and Consumption and Sustainable Resource Management programs, and OECD's Sustainable Materials Management framework.

There are several similar and overlapping efforts to define and conceptualize a closed loop lifecycle of product and materials management, with many of these efforts being spearheaded by government agencies, entrepreneurs, scientists and non-governmental organizations. While similar to SMM, these product lifecycle models focus largely on the end-of-life management of materials while SMM focuses on the impacts materials, products and services have on the environment such as eutrophication, acidification, ozone layer depletion, global warming and aquatic toxicity as well as energy and water use.
