ABOUT TEYSHA

Teysha is the result of over a decade of searching, of understanding a problem and striving for a solution. The Teysha team have developed unique IP, in partnership with the world’s leading research scientists, and partnered with the UK’s elite process and commercialisation specialists, to develop a product and company that has an entirely new and unique solution to plastic pollution.

Introduction

It’s likely that about 10m tonnes of plastic currently ends up in the oceans each year. In 2010 scientists from the National Center for Ecological Analysis and Synthesis and the University of Georgia in Athens estimated the figure as 8m tonnes, and forecast that to rise to 9.1m tonnes by 2015. The same study, published in the journal Science in 2015, surveyed 192 coastal countries contributing to ocean plastic waste, and found that Asian nations were 13 of the 20 biggest contributors.

Technology

Teysha’s natural product polycarbonate platform creates a wide range of polymers with tunable properties and practical applications to meet the growing demand for sustainable plastics. The platform invention provides the design of synthetic strategies for the development of polymer materials that originate from renewable resources, exhibit novel combinations of strength and toughness, as well as undergo hydrolytic breakdown to biologically beneficial by-products.

Applications

One significant strength of the technology is its inherent versatility as it is truly more of a platform than a single polymer system. It can be thought of as a “plug-and-play” system where various modified natural product monomers and various thiol co-monomers can be used. In addition to the co-monomers, various solvents and additives can be used to modify the properties of the final polymer network. This allows for the formation of a variety of final products that can vary from hard and stiff materials to soft, which can be directly applied to current plant machinery with low capital cost.

Policy

“Around 99% of the feedstock for plastics is fossil fuels, so we are looking at the same companies, like Exxon and Shell, that have helped create the climate crisis. There is a deep and pervasive relationship between oil and gas companies and plastics.”

Louise Edge / Greenpeace UK’s senior oceans campaigner

“It is by working with these companies, with policy makers, with cities, with innovation to design bio-benign products – that we will tackle this. There isn’t a company out there which wants to see its logo in the ocean or in a river”

Dame Ellen MacArthur / The Ellen MacArthur Foundation, 2017

“If we continue like this, by 2050, we will have more plastic in the ocean than fish,”
