This World Economic Forum article on the economic impact of waste, on top of its environmental impact, gives an additional argument as to why we urgently need to redress our wasteful linear economy business model in favour of a circular system.
The circular economy diagram from the Ellen MacArthur Foundation gives a visual guide to the many methods of material re-purposing that occur in a circular economy. Some processes are tried and tested, others will come from new and emerging technologies. The message is clear though, the circular economy is good for business.
