Industry research partnership leads to new patented technology for capturing hospital anesthetic gases

Tuesday, December 15, 2015

Grand River Hospital (GRH) has formally activated its halogenated drug recovery (HDR) system, developed through a research initiative lead by Bill Anderson, professor of chemical engineering, and Class 1 Inc. of Cambridge. This new technology will help battle climate change as it captures waste anesthetic gases exhaled by patients undergoing surgery.

Exhaled air from surgical patients is diverted into specialized equipment in a mechanical room. The anesthetic gases are captured and stored in canisters rather than being released into the environment. The canisters are replaced regularly. Just a single 240 mL bottle of anesthetic gas released into the atmosphere is the equivalent of 1.4 tonnes of carbon dioxide emissions.

“Bill Anderson and his team have given us a worldwide competitive advantage,” says Marian Marshall, vice president of operations at Class 1 Inc., in Cambridge, Ontario. “With this research we have leapfrogged five years ahead of the competition and have invented an innovative anesthetic gas recovery solution for hospitals and medical facilities worldwide."
