And like renewables, it will be good for business and the wider economy. In the 20th century, products were made, used and at the end of their useful lives either incinerated or sent to landfill.

In the 21st century, those products will increasingly follow circular, rather than linear pathways: products and their component parts will be recycled, remanufactured and refurbished.

This transition to circular economies is well summarised by Accenture analysts Peter Lacy and Jakob Rutqvist, in an excellent book, Waste to Wealth.
