How to Dispose of a Propane Tank
A propane tank must never go in household waste, kerbside recycling, or a dumpster. Even an "empty" one holds residual gas under pressure and is a genuine explosion risk in a compactor truck. The good news: exchange cages take standard BBQ tanks free, and it takes two minutes.
Short answer: take a 20 lb BBQ tank to any propane exchange cage — the ones outside supermarkets and hardware stores. They'll take the old one whether or not you buy a refill.
Why this one genuinely matters
Propane tanks are among the most dangerous items people routinely put in the bin. A tank that reads empty still contains liquid propane residue and vapour under pressure. Crushed in a collection truck, punctured at a sorting facility, or heated in a landfill fire, that becomes an explosion — and waste industry incident reports feature them regularly.
Refuse crews have been seriously injured by tanks in household waste. This is the one item on this site where "just bin it" carries real risk to someone else.
Where to take them
| Tank type | Where | Cost |
|---|---|---|
| 20 lb BBQ tank | Propane exchange cage (Blue Rhino, AmeriGas and similar) | Free |
| 20 lb BBQ tank | Propane refill dealer | Free or small fee |
| 1 lb camping canister | Household hazardous waste | Free |
| 30–100 lb tank | Propane dealer or HHW | Free to $20 |
| Large / residential tank | Supplier — they own it | They collect it |
| Any tank, damaged or rusted | Propane dealer or HHW — tell them | Usually free |
Exchange cages take old tanks
The cages outside supermarkets, petrol stations and hardware stores accept old tanks even if you're not exchanging for a full one. Most people don't realise this — you can simply hand it over. If the cage is locked, ask at the customer service desk.
Propane dealers
Any business that refills tanks will take an old one, and they're the right destination for anything unusual, oversized, damaged or out of certification. They handle tanks daily and can depressurise them safely.
The 1 lb camping canisters
These are the disposable green cylinders for camping stoves and lanterns, and they're the ones people most often get wrong.
- They can't be refilled (legally, in most contexts) and can't be exchanged.
- They still contain residual propane even when the stove stops working.
- Household hazardous waste is the correct destination. Most county HHW sites accept them.
- Some outdoor retailers and campgrounds run collection schemes.
- Don't puncture them yourself. Puncturing tools exist and some jurisdictions permit their use, but it releases propane and is genuinely hazardous if done wrong.
They're a known problem for waste facilities precisely because they look small and harmless.
Expired and damaged tanks
US propane tanks carry a manufacture date stamped on the collar and are typically certified for 12 years, after which they need requalification or retirement. Exchange cages routinely reject out-of-date tanks — but a propane dealer will still take one for disposal.
Take a tank straight to a dealer, and mention the condition, if it is:
- Visibly rusted, pitted or dented
- Leaking, or smells of gas
- Damaged around the valve
- Been in a fire
Transporting it safely
- Keep it upright and secured. A rolling tank can shear its valve.
- Valve closed, and fit the safety cap or plug if you have it.
- Ventilate the vehicle — window cracked open. Propane is heavier than air and pools low.
- Never leave a tank in a hot car, and never in a boot on a hot day for any length of time.
- Never in the passenger compartment if you can avoid it.
If you're getting rid of the grill too
Take the tank off first and deal with it separately — that's the single most important step. The grill itself is mostly steel and goes to a scrap yard or bulk pickup. See our grill disposal guide.
Common questions
Can I throw away a propane tank?
No — not in household waste, kerbside recycling, or a dumpster, under any circumstances. It's an explosion risk for collection crews and facilities.
Is propane tank disposal free?
Yes for standard 20 lb BBQ tanks at exchange cages, and usually at propane dealers. Camping canisters are free at household hazardous waste sites.
Do I have to buy a refill to drop off an old tank?
No. Exchange cages and dealers will generally take an old tank without a purchase.
What if my tank is out of date?
Exchange cages will refuse it, but a propane dealer will take it for disposal. That's the right destination for anything expired, rusted or damaged.
Can I put an empty camping canister in the recycling?
No. They're not truly empty and they're a fire risk in sorting equipment. Household hazardous waste is the correct route.
Is a tank worth anything as scrap?
Only once professionally depressurised and cut, which scrap yards won't do for you. Don't attempt it — a sealed pressure vessel is not a DIY scrapping job.
