2nd November 2026
Nitrous oxide, commonly known as laughing gas, has become an increasingly expensive problem for Britain's waste industry. What might appear to be nothing more than discarded metal canisters is creating serious safety hazards, damaging industrial equipment and costing millions of pounds.
The question is whether the Government should go further than its existing restrictions and control the sale of nitrous oxide canisters more tightly.
Nitrous oxide has legitimate uses in hospitals, dentistry, food production and catering. However, it has also become widely associated with recreational drug use, particularly among younger people. Canisters are often discarded in streets, parks and household rubbish, with consequences that extend far beyond littering.
The danger becomes particularly serious when these pressurised containers enter waste collection vehicles and processing facilities. They can explode when crushed or exposed to heat, damaging machinery and creating risks for workers. At waste-to-energy plants, explosions can damage furnace equipment and force costly shutdowns.
The scale of the problem is attracting growing attention from waste operators. SUEZ, one of Britain's major waste management companies, has reported thousands of canister-related explosions across its facilities. The resulting disruption and repairs have been estimated to cost millions of pounds.
These are not simply costs for private waste companies. Ultimately, higher operating costs can feed through to councils, businesses and taxpayers.
Existing restrictions are not solving everything
The Government introduced tighter controls in November 2023, classifying nitrous oxide as a Class C drug under the Misuse of Drugs Act 1971. Possession is illegal where the intention is to inhale it for its psychoactive effects. Unlawful supply can carry a prison sentence of up to 14 years.
However, legitimate uses remain exempt. Hospitals, dentists, food manufacturers and catering businesses can continue to obtain the gas for appropriate purposes.
The distinction is important. A complete prohibition would create unnecessary difficulties for businesses and medical services which depend on nitrous oxide.
But should that mean that large canisters can continue to be sold through retail channels with relatively little practical control over their eventual use?
There is a case for restricting sales to verified commercial customers, limiting quantities and requiring retailers to check that purchases have a genuine purpose. Manufacturers and suppliers could also be required to provide better collection and disposal arrangements.
Who should pay for the damage?
One proposal worth considering is a refundable deposit on canisters. Customers would pay a small additional amount when purchasing them and receive it back when returning the empty container to an approved collection point.
This would encourage responsible disposal and give manufacturers and retailers a greater incentive to organise collection.
Yet the Government has so far shown little enthusiasm for going further. In a parliamentary answer on 18 June 2026, the Home Office said it had no current plans for additional sales restrictions. On the same date, the Department for Environment, Food and Rural Affairs confirmed that it was not considering a deposit-return scheme.
That position deserves further examination, particularly when waste operators are reporting substantial disruption and financial losses.
A problem that cannot simply be ignored
The issue is not whether legitimate users should lose access to an important product. It is whether unrestricted access through retail channels is justified when misuse creates risks for the public and those working in the waste industry.
Britain has already recognised that recreational misuse of nitrous oxide requires legal controls. It now needs to consider whether the supply and disposal arrangements are adequate.
Why should waste workers face the danger of exploding canisters, while councils and taxpayers potentially carry the financial consequences?
A system that protects legitimate businesses while making suppliers responsible for safer sales, collection and disposal would be a sensible subject for serious debate.
The figures are supported by reporting from SUEZ and the waste industry, while the existing legal position and the Government's June 2026 responses are documented in parliamentary records.
From vapes to jabs: A wake-up call For Britain’s bins
SUEZ in the UK has revealed the ten products causing the biggest challenges for Britain’s recycling industry.
Electronic devices are the worst offender, causing hundreds of fires and £1 billion in damage every year.
Nitrous oxide canisters and mattresses also rank among the biggest culprits, alongside nappies.
Weight loss jabs tipped to be a potential future problem as SUEZ calls for a new nationwide scheme with safe and accessible disposal routes.
Items containing lithium-ion batteries have been named the most dangerous items Brits routinely throw away, as new research reveals the everyday products disrupting the UK’s recycling system.
Leading recycling company SUEZ has revealed the scale of the cost, damage and disruption caused by the ten items causing the biggest problems to Britain’s waste system. The list ranges from mattresses and nappies to at-home injections. SUEZ is today calling on government to hold manufacturers to account for designing products with their end of life in mind.
Taking the top spot are vapes, with more than 150 discarded devices turning up at one recycling site every day. SUEZ reports that 368 fires last year were caused by lithium-ion batteries in vapes and other electricals igniting when crushed or damaged during processing. Across the industry, these fires are estimated to cause more than £1 billion in damage each year.
Nitrous oxide canisters rank second. SUEZ saw more than 7,000 explosions at its energy-from-waste facilities in 2025 – more than 20 per day.
Mattresses ranked third due to the volume and size of products. SUEZ UK revealed it handled 7,500 tonnes of discarded mattresses in 2025 – more than the weight of the Eiffel Tower.
SUEZ has also warned that weight loss jabs could become the waste industry’s next headache, with an estimated 104 million now prescribed every year, posing a safety risk to frontline staff if discarded incorrectly. With their popularity skyrocketing, SUEZ is calling for a new nationwide scheme with safe and accessible disposal routes to prevent used syringes ending up in Britain’s recycling.
Dr Adam Read, Chief Sustainability Officer at SUEZ in the UK, said: “What we throw away has changed dramatically. Five years ago, vapes barely registered as an issue, but today, they’re the most problematic product we deal with.
“For every product bought in shops or online, government need to hold manufacturers to account for designing products with their end of life in mind. The issues we’re currently seeing related to items containing batteries should be a wake-up call.”
The top ten problematic materials include:
Vapes
Batteries
Nitrous Oxide
Mattress
Flexible plastic packaging
Nappies and absorbent hygiene products
Paint and chemicals
Food-contaminated recycling
At-home injections
Compostable packaging
