Chestnut Biopolymers

About us

Chestnut Biopolymers - Plant Based Biodegradable plastics - made robustly not to last (TM)

Which of your products made from PP, PE or PS could you replace with our bioplastic, removing any risk of micro or nano-plastics entering the environment and food chain?

At Chestnut Biopolymers, we believe in nature’s intelligence. That’s why we’ve named ourselves after one of its finest champions: the Chestnut tree. In the English countryside, no other native tree grows as fast and stores as much carbon over its lifetime. It’s not just a tree—it’s a force of nature. A living engine of carbon capture. A beating heart in the fight against climate change.
 
Just like the tree, Chestnut Biopolymers is built to grow quickly and create lasting environmental value. We develop biodegradable, plant-based biopolymers designed to match the strength and performance of fossil plastics—without leaving behind the toxic legacy. Our materials are strong in use, but gentle in afterlife: designed to break down safely in the natural environment, not linger for centuries as micro-plastics and nano-plastics.
 
We work with manufacturers across sectors—from medical disposables and packaging to consumer goods—helping them replace polypropylene, polyethylene, and polystyrene with sustainable, plant-based alternatives. These bioplastics are a drop-in alternative that don’t require new machinery or retooling. This is a seamless transition to better materials, grounded in real science and real impact.
 
Our materials are made from renewable, carbon-sequestering feedstocks. And we measure our success not only by what we make—but by what we leave behind: nothing harmful, nothing persistent. Just a cleaner system.
 
As we like to say:
Biodegradable Biopolymers. Made Robustly Not to Last.
 
Chestnut Biopolymers is the beating heart at the centre of the drive to replace fossil plastics—the living counterpart to the Chestnut tree’s role in nature. Together, we are tackling the damage done by the fossil sector, and beginning to reverse the spread of plastic pollution, from landfills to oceans to the very air we breathe.
 
Join us in building a world beyond fossil plastics—where material innovation helps restore the balance.
