Fluorinated anaesthetic gases (F-gases), such as desflurane, sevoflurane and isoflurane, account for up to 80% of anaesthetic-related healthcare emissions and can persist in the atmosphere for up to 14 years. EnviroMedical addresses this through a five-step capture and recycling system that collects exhaled gases directly from patients, stores them in secure reusable canisters, and returns remanufactured anaesthetic agents to hospitals, enabling a circular supply. The system integrates seamlessly with existing anaesthetic equipment, captures up to 99.9% of exhaled gases, and complies with EU Regulation (2024/573).

Nitrous oxide (N₂O), which contributes up to 30% of anaesthetic emissions and has a global warming potential up to 300 times that of CO₂, is addressed through Medclair’s destruction technologies, which eliminate over 99% of exhaled N₂O by converting it into nitrogen and oxygen. This is supported by central destruction units for multi room settings and real time monitoring systems that ensure staff safety and regulatory compliance.

HIHI delivered two evaluation sessions for Enviromedical with expert assessment from biomedical engineering, anaesthesia and ICU.

Experts agreed that:
The Enviromedical anaesthetic F-gas capture system represents a clinically viable solution that is compatible with most major anaesthetic machines and fully compliant with current EU regulations
and
The Enviromedical nitrous oxide destruction solution similarly prioritises safety and seamless integration, operating as a plug-and-play system designed to protect both patients and healthcare staff from NO₂ exposure risks in theatres and intensive care settings.
