Epoch Biodesign lands fresh funding for circular plastics push
London-based biotech startup Epoch Biodesign has raised £9 million in new funding to build what it says will be its largest nylon 6.6 biorecycling facility to date. The round is led by climate-focused investor Extantia and early-stage fund Kompas VC, underscoring growing venture appetite for technologies that can decarbonise the plastics and textiles value chain.
A new approach to hard‑to‑recycle nylon
Nylon 6.6 is widely used in automotive components, performance textiles, industrial applications and consumer goods, but is notoriously difficult to recycle using conventional mechanical methods. As a result, most waste ends up in landfills or is incinerated, locking in a heavy carbon footprint.
Epoch Biodesign is developing engineered enzymes and bespoke bioprocesses designed to break down complex polymer chains and convert them into reusable chemical building blocks. By targeting nylon 6.6, one of the most challenging engineering plastics, the company aims to prove that biorecycling can compete with virgin petrochemical production on both cost and performance.
Scaling the largest nylon 6.6 biorecycling plant
The newly raised £9 million will fund the design, construction and optimisation of what the company describes as its largest demonstration-scale plant. The facility is expected to process industrial nylon waste streams and post‑consumer materials, providing partners with a lower‑emissions alternative to traditional disposal and re-manufacturing.
According to the company, the plant will serve as a critical validation step, bridging the gap between lab-scale success and fully commercial operations. By integrating advanced biocatalysts, process control systems and downstream purification, Epoch Biodesign aims to deliver recycled monomers that meet stringent specifications required by manufacturers.
Strategic backing from climate‑tech investors
Lead investors Extantia and Kompas VC focus on technologies that can materially reduce industrial emissions and enable a more circular economy. Their backing signals confidence that biologically driven recycling can scale into a viable alternative to fossil-based feedstocks in sectors ranging from textiles to automotive and electronics.
With this funding, Epoch Biodesign joins a growing cohort of European startups seeking to replace linear, waste-heavy plastics systems with circular models powered by synthetic biology, industrial biotechnology and data-driven process engineering. If successful, the company’s nylon 6.6 plant could serve as a blueprint for biorecycling other high-value polymers at scale.
