Treating Nitrous Oxide Waste in Ireland

laughing gas

Nitrous oxide (N₂O) is a greenhouse gas 273 times more harmful than carbon dioxide. With thousands of canisters entering Ireland's waste stream from healthcare, catering, and other sectors, the environmental impact is significant and until now, there has been no local treatment solution.

At Veolia, we've developed Ireland's first on-island nitrous oxide treatment system. We've adapted hospital-grade catalytic technology for industrial-scale application, ensuring the system meets Ireland's regulatory, environmental, and operational requirements.

This pioneering solution eliminates the need to export canisters abroad for treatment, reducing logistics emissions while providing Irish organisations with a cost-effective, sustainable alternative.


Safe, efficient and sustainable treatment

Veolia’s solution uses advanced catalytic decomposition to break down nitrous oxide into harmless nitrogen and oxygen, the same elements that make up the air we breathe. This process is not only highly effective but also remarkably efficient.
 

This approach delivers immediate, tangible benefits:
 

99% conversion rate: virtually complete elimination of nitrous oxide

Energy self-sufficient: the heat generated during decomposition sustains the reaction

Massive carbon reduction: capable of processing up to 470 canisters and 500 ampoules daily, preventing approximately 23,000 tonnes of CO₂ equivalent emissions annually

Net carbon-avoidance efficiency exceeding 99.5%: one of the most sustainable waste treatment solutions available

Local treatment: eliminates the environmental cost and complexity of exporting waste overseas
