SageTech Veterinary
During a general anaesthetic, 95% of the gas that is administered goes unused; only 5% is used in sedating the patient.
Veterinary anaesthetic gases, isoflurane and sevoflurane, are classed as F-Gases (fluorinated gases) and have high global warming potential.
The 95% of anaesthetic that is unused is either vented from the vet practice or captured on terminal filters and sent for incineration or landfill.
There is strong evidence to suggest that terminal filters are not efficient at securing the waste anaesthetic and pose a safety risk to practice employees.
It has been independently reported that about 20% of a veterinary clinic's carbon footprint is as a result of anaesthetic gases.
SageTech Veterinary has developed patented technology that captures 85% of the waste gas that is exhausted from the anaesthetic circuit. The SageTech solution captures the waste gas onto reusable filters from which it can be recovered, purified, and reused.
By reusing the anaesthetic, the need for virgin anaesthetic manufacture is dramatically reduced, further reducing the carbon footprint of anaesthetic gases.
SageTech launched its solution in the UK in 2025, with capture filters widely available through all main wholesalers. The company is embarking on its growth journey in the UK, Europe, and further afield.
