 In closed loop recycling, a material is captured at the end of life and introduced back into the manufacturing process to make a new product 

The Organization for Economic Co-operation and Development (OECD) formed in 1960 and currently comprising 35 member countries including the United States, Canada, Mexico, Japan and 23 countries in the European Union, works to foster economic prosperity and end poverty by promoting economic growth and financial stability for governments around the world while also taking into account the implications that economic and social growth have on the environment.Since the 1980s, the OECD has worked to promote policies that prevent, reduce and manage waste in ways that mitigate environmental impacts.It has become clear over time that increasing economic activity and materials consumptions calls for a systematic materials based approach to managing waste, one that seeks to incorporate materials back into the manufacturing process at the end of their life, in what is commonly referred to as a “cradle to cradle” approach to materials management as opposed to the traditional “cradle to grave” waste management approach.
