In the natural world nothing is wasted. Waste from one species is food for another species and energy and nutrients are continuously recycled.Yet our modern economic system has been built on a linear model of Make -> Consume ->Dispose.
The Cradle to Cradle concept by William McDonough and Michael Braungart aims to eliminate the waste going to landfill and conserve scarce resources. In this nature inspired circular model the waste from products are cycled back into the production of other products.
This Circular Economy is one of the important changes that needs to be taking place in the way we manage our economic system!
