The Ellen MacArthur Foundation’s report on the Economics of a Circular Economy invites readers to imagine an economy in which today’s goods are tomorrow’s resources, forming a virtuous cycle that fosters prosperity in a world of finite resources. This change in perspective is important to address many of today’s fundamental challenges. Traditional linear consumption patterns (‘take-make-dispose’) are coming up against constraints on the availability of resources. The challenges on the resource side are compounded by rising demand from the world’s growing and increasingly affluent population. As a result, we are observing unsustainable overuse of resources, higher price levels, and more volatility in many markets.
