Blue-Zone Technologies Ltd. has demonstrated a technology to capture, reclaim and purify halogenated inhalation anaesthetic gases used in hospital operating rooms, much of which escapes during medical application. These are very aggressive GHGs, some having global warming potential up to 1,900 times that of carbon dioxide. The Blue-Zone technology, broadly called Delta™, can capture and reconstitute these vented gases. The anaesthetic can be re-used 10 to 20 times. This offers hospitals significant savings in their expenditures on anaesthetic gas while preventing harmful GHG emissions.
