A consortium including the University of Plymouth has been awarded £3.6 million to advance technology which captures, recovers and recycles volatile anaesthetic gas waste for future reuse.
Anaesthetic gases released during medical procedures in hospitals and other healthcare settings are responsible for emitting around 4 million tonnes of greenhouse emissions (CO₂e) worldwide each year. This makes them a major contributor to the carbon footprint of healthcare and, ultimately, to global warming.
To address that, a group of organisations will work together to enhance pioneering technology developed by SageTech Medical, a Devon-based company revolutionising sustainable innovation in the healthcare sector.
SageTech’s technology safely captures anaesthetic waste during procedures so it can be recovered and recycled. The recovered waste is then converted into reusable anaesthetics, helping create a circular economy, cut clinical costs and support NHS Net Zero goals by reducing emissions.
The new programme of work, funded through Innovate UK’s Sustainable Medicines Manufacturing Innovation Programme (SSMIP), will allow SageTech to expand manufacturing capacity and increase production of its patented recycling systems to meet growing demand in the UK and internationally.
It will also help the consortium accelerate the development of new, data-driven sustainable gas recovery and reuse technology, while enhancing existing systems by improving energy efficiency and minimising waste.
In addition to SageTech and the University of Plymouth, the consortium will bring together experts from the NIHR HealthTech Research Centre (HRC) in Sustainable Innovation – which is hosted by the Royal Devon University Healthcare NHS Foundation Trust in partnership with the University of Exeter – as well as the Manufacturing Technology Centre and the Centre for Process Innovation.

SageTech is delighted to be working with some of the brightest scientists and engineers at MTC and CPI, and the opportunity to work again with trusted partners at the NIHR HRC in Sustainable Innovation and the University of Plymouth is very exciting. This funding will enable us to build on our technology – improving sustainability, reducing costs and reaching even more hospitals across the UK, EU and beyond.

The project builds on a previous collaboration between the University and SageTech that was supported by the Devon Net Zero Innovation Fund. It also complements existing work at the University centred around converting waste products into new and useful materials.
All of that work is led by Dr Lee Durndell , Associate Professor in Clean Energy Transitions, and for the new project he will focus on developing regeneration and upcycling routes that convert spent anaesthetic-capture materials into functional adsorbents, photocatalysts and graphitic carbons for battery, nuclear and broader energy applications.

Our work demonstrates how smart materials innovation can deliver real sustainability gains for the NHS while advancing national priorities in critical materials and energy security.

This circular materials approach connects NHS sustainability with the UK’s wider clean-energy, critical materials and advanced-manufacturing priorities, while our research will enhance the project’s commercial potential by creating new pathways for high-value carbon technologies.

Collaboration is essential to driving sustainable innovation in healthcare, and we’re proud to continue working alongside SageTech Medical and our consortium partners to advance this ground-breaking technology. This funding will enable us to evaluate and scale the technology, ensuring it delivers long-term value for the NHS – benefiting patients, staff and the environment.
