Twelve Pioneers Answering Circularity's Hardest Questions

Over a year we sat down with twelve people building circular materials businesses - at Wild Plastic, Lignin Industries, Human Material Loop, On, BASF, PAKKA, Ocean Conservancy, MAGNO, Chemical Recycling Europe and Plastics Europe Deutschland.

We asked all of them the seven questions the industry keeps stepping around. What does circularity actually cost? Who pays for collection? Does mass balance - the accounting method that lets recycled input be attributed to specific output - mean anything in practice? And why do good materials die between the pilot plant and the production line?

Almost none of them answered the way I expected.

A pattern emerged instead. Circular materials scale when they are drop-in compatible, priced at parity and unglamorous. Not when they are revolutionary. Integration beats disruption. Economics beats virtue. Pull beats push.
