Rethinking the Future of Plastics with DePoly and Xampla

There could be more plastic than fish in the ocean by 2050, according to an Ellen MacArthur Foundation report.

Plastic pollution is a huge problem — but it’s not one that is irreversible if we act quickly enough.

In this episode, we explore and address the issue of plastics with two founders that are striving to make a change: Samantha Anderson, CEO of DePoly, and Simon Hombersley, CEO of Xampla.

Both companies are looking to eliminate plastic pollution but tackling the problem from two different angles. DePoly (STATION F startup in the L’Oréal Program) has developed a cutting-edge technology to recycle PET plastic. Xampla (Cambridge University spin-out) has developed a plant-protein material that provides a natural alternative to single-use plastic.

Samantha Anderson, CEO of DePoly, has a Ph.D in chemistry from EPFL – Valais and is passionate about developing sustainable chemistry businesses that help fight global issues we currently face.
