This episode features an interview with Cat Fletcher, one of the UK's most articulate and passionate reuse activists. She played a key role in the founding of Freegle, a UK version of Freecycle, and has carved out a niche in Brighton, promoting reuse within the heart of her local council. br /

The real question is whether government and innovators can help us to divert more from landfill and the shredder, in this twitchy, impatient era.
