CGN 07 focuses on a growing problem quietly making its way through the waste industry: nitrous oxide cream chargers.
Used widely by coffee shops, bakeries, catering outlets and commercial kitchens, these large gas canisters are increasingly being discarded into general waste and recycling streams despite still containing residual pressure and oxidising gas hazards.The problem is simple: They look empty. They are often not.
Once inside compactors, balers, MRFs or incinerators, these cylinders can cause fires, explosions, equipment damage and significant operational disruption.
This Circular Guidance Note explains:
- why cream chargers remain hazardous after use
- their correct technical classification
- why they should never enter routine waste streams
- and the correct route for compliant treatment
Because pressure vessels belong in specialist treatment - not general waste. RPS 289 - link - More like this (aerosols) - link - more like this (CGN 06) - link
As with all documents within the CGN (Circular Guidance Note) series, every effort has been made to ensure the information provided is factual, practical, and helpful at the time of writing however, legislation changes, guidance evolves and occasionally mistakes happen. If you spot anything within this CGN that is incorrect, misleading, outdated or could be better explained, please leave a comment below together with supporting information or clarification. Following review and verification, corrections or revisions will be made where appropriate and contributors will happily be credited for their input should they wish. The aim of the CGN series is not simply to publish information but to build a growing, reliable, real-world resource library for everyone involved in waste, recycling, compliance and circular economy discussions.
I have always believed that in waste management, getting it right matters more than pretending to already know everything.
