Sustainable anaesthesia solution

During an operation, only 5% of anaesthetic gases are absorbed and metabolised by the patient, meaning that 95% of this volatile anaesthetic is expelled into the atmosphere as waste.

Once exhaled into the atmosphere, waste volatile anaesthetic agents stay around for a long time and have high tropospheric lifetimes and subsequently high global warming potentials. With the NHS committed to an 80% reduction in CO2e from anaesthetic gases by 2032, an innovative solution is needed.

SageTech Medical provides a safe, sustainable and easy to use innovative circular economy solution which captures, recovers and recycles harmful waste volatile anaesthetic gases. By preventing these exhaled gases from polluting the atmosphere, the company provides hospitals with a straightforward solution to make a real difference to their carbon footprint, public health and the environment.

The gas capture system (SID-Dock) safely captures 99.9% of exhaled mixed volatile anaesthetic agents (sevoflurane, isoflurane and desflurane), through actively controlled adsorption onto two reusable capture canisters (SID-Cans). Full SID-Cans are collected from the hospital, emptied at regional SID-Hub facilities, and quality checked before being returned for reuse. 

Recycled waste volatile agents can be repeatedly recycled and reused as an anaesthetic, therefore reducing the significant burden associated with virgin drug manufacture and completing the circular economy solution.
