We See Waste as an Opportunity

Born in Cambridge. Built for Circularity.

Protonera began with a shared conviction on circular chemistry over five years ago at the University of Cambridge, where the founders’ research expertise converged on one urgent quest.

Creating value from waste.

Chemoenzymatic reforming (CR) was born by combining enzymology with reforming to extract hydrogen, chemicals and monomers from plastic waste.

We Don’t Just Build Technology We Build Ecosystems

Protonera’s CR platform is more than a waste treatment solution. It’s a foundation for a circular economy one where materials are reused, energy is clean, and chemistry drives regeneration.

Whether you’re looking to process complex waste, access sustainable chemical inputs, or pilot circular models, our technology adapts to your needs and infrastructure.

Impact & Policy

Global Plastics-to-Chemicals Impact, Starting in Europe and the UK.

Protonera is designed for a global market of recyclers, manufacturers, cities and investors who want to turn waste plastics into high-value molecules while supporting local climate and circular economy goals.

Environmental and System Impact

Protonera converts mixed, contaminated plastic streams into hydrogen, monomers and organic acids. This supports partners that want to:

Increase diversion of plastics from landfill and incineration.
Close the loop across industries.
Replace fossil-based inputs with waste-derived molecules.
Meet and exceed EPR, ESG, and Net Zero goals to translate the impact to you.

Quantified impact metrics

Key Levers of Impact

Three levers turn Protonera’s chemistry into measurable impact for partners:

Contaminant toleranceEnabling more real-world plastic waste sources to be processed rather than discarded.
High-value outputsHydrogen, monomers and organic acids that can displace more carbon-intensive or fossil alternatives.
Modular mild-condition reactorsDesigned for scalable, distributed deployment near waste sources and existing industrial sites.
