Why don't more manufacturers embrace the principles of the circular economy? It's a pertinent question, given the dire state of the recycling industry.

Manuela Saragosa speaks to one company that has already implemented the principles of the circular economy. Cardboard box manufacturer DS Smith tracks its products throughout their life, and can reuse the fibres they contain up to 25 times, according to the firm's sustainability lead, Sam Jones.

So why don't more manufacturers do the same? Manuela speaks to circular economy expert Alexandre Lemille, Jarkko Havas of the Ellen MacArthur Foundation, and Josephine von Mitschke-Collande of EIT Climate-KIC in Switzerland.
