Cradle to Cradle was developed by the German chemist Prof. Dr. Michael Braungart and The US American architect William McDonough at the end of the 1990s. Cradle to Cradle® stands in contrast to the widespread linear production principle “cradle to grave” in which materials often flow from their sources to their disposal without conscious consideration given to long-term protection of natural resources.
Cradle to Cradle, on the other hand, is modeled on processes in nature in which there is no such thing as waste. Instead, every end product functions as nutrients for something new. Raw materials required for production are developed so that they can be held in biological and technical cycles. Materials are chosen that are suitable for a safe and complete return to the biosphere or for recovery and high-quality reuse.
