Nice article in Fast Company introducing the principles of Circular Economy strategies, mostly taken from the Ellen MacArthur Foundation.

A circular economy is one where goods are restored and regenerated more widely, moving from a system of virgin inputs and piles of waste to one that returns used products to a useful state. It is also an economy that minimizes resource use by moving away from individual ownership towards more leasing, renting, and sharing. The aim is to cut environmental damage and allow companies to keep control of the value in their products.
