89 Simon Hombersley – plastics from plant protein

Circular Economy Podcast Ep89 Simon Hombersley - Xampla

Simon Hombersley, CEO of Xampla, shares the story of how this Cambridge University spin-out has created the world’s first plant protein material for commercial use, pioneering the replacement of the most polluting plastics with natural alternatives.

Xampla’s ambition is to become the leader in natural polymers, and it’s been developing its natural polymer resin over the past 15 years. The polymer, which Xampla describes as a breakthrough material, performs just like synthetic polymers, but decomposes naturally and fully without harming the environment at the end of life.

Xampla is the first UK University spin-out to be awarded B Corp status and is working with multi-national companies, including Britvic, Gousto and Croda on new technologies.

Podcast host Catherine Weetman is a circular economy business advisor, workshop facilitator, speaker and writer.  Her award-winning book: A Circular Economy Handbook: How to Build a More Resilient, Competitive and Sustainable Business includes lots of practical examples and tips on getting started.  Catherine founded Rethink Global in 2013, to help businesses use circular, sustainable approaches to build a better business (and a better world).
