Cradle-to-cradle design

Cradle to Cradle design (also referred to as Cradle to Cradle, C2C, cradle 2 cradle, or regenerative design) is a biomimetic approach to the design of products and systems. It models human industry on nature's processes viewing materials as nutrients circulating in healthy, safe metabolisms. It suggests that industry must protect and enrich ecosystems and nature's biological metabolism while also maintaining a safe, productive technical metabolism for the high-quality use and circulation of organic and technical nutrients.〔''Cradle to Cradle: Remaking the way we make things'', 2002.〕 Put simply, it is a holistic economic, industrial and social framework that seeks to create systems that are not only efficient but also essentially waste free.〔Lovins, L. Hunter (2008). (Rethinking production ) in ''State of the World 2008'', pp. 38–40.〕 The model in its broadest sense is not limited to industrial design and manufacturing; it can be applied to many aspects of human civilization such as urban environments, buildings, economics and social systems.
The term Cradle to Cradle is a registered trademark of McDonough Braungart Design Chemistry (MBDC) consultants. Cradle to Cradle product certification began as a proprietary system; however, in 2012 MBDC turned the certification over to an independent non-profit called the Cradle to Cradle Products Innovation Institute. Independence, openness, and transparency are the Institute's first objectives for the certification protocols.〔("Ask the Experts: Why Hasn't Cradle-to-Cradle Design Caught On Yet?" )〕 The phrase "cradle to cradle" itself was coined by Walter R. Stahel in the 1970s. The current model is based on a system of "lifecycle development" initiated by Michael Braungart and colleagues at the ''Environmental Protection Encouragement Agency'' (EPEA) in the 1990s and explored through the publication ''A Technical Framework for Life-Cycle Assessment''.
In 2002, Braungart and William McDonough published a book called ''Cradle to Cradle: Remaking the Way We Make Things'', a manifesto for cradle to cradle design that gives specific details of how to achieve the model. The model has been implemented by a number of companies, organizations and governments around the world, predominantly in the European Union, China and the United States. Cradle to cradle has also been the subject of many documentary films, including the critically acclaimed ''Waste=Food''.〔http://www.sundancechannel.com/films/500068530/〕
==Introduction==
In the cradle to cradle model, all materials used in industrial or commercial processes—such as metals, fibers, dyes—fall into one of two categories: "technical" or "biological" nutrients. ''Technical nutrients'' are strictly limited to non-toxic, non-harmful synthetic materials that have no negative effects on the natural environment; they can be used in continuous cycles as the same product without losing their integrity or quality. In this manner these materials can be used over and over again instead of being "downcycled" into lesser products, ultimately becoming waste.
''Biological Nutrients'' are organic materials that, once used, can be disposed of in any natural environment and decompose into the soil, providing food for small life forms without affecting the natural environment. This is dependent on the ecology of the region; for example, organic material from one country or landmass may be harmful to the ecology of another country or landmass.〔
The two types of materials each follow their own cycle in the regenerative economy envisioned by Keunen and Huizing.
