This is why interest in the circular economy is gaining ground. This is about making products that are designed to have several product life cycles via reuse, remanufacture, refurbishment or recycling systems. Tackling the problem of climate change, the circular economy is also about using more renewable energy. It makes business sense, creating new value out of materials that would otherwise be thrown away. Recent research from McKinsey and the Ellen MacArthur Foundation suggest that global industry could generate at least a trillion additional dollars every year as a result of material cost savings.
