How to Dispose of a Propane Tank
It cannot go in the trash, and you should not try to empty it yourself.
A propane cylinder should never go in household trash, curbside recycling, or an ordinary scrap bin while it holds propane or still has its valve attached, because a pressurized container creates fire and explosion hazards. The realistic routes are a cylinder exchange program, a propane supplier that accepts used cylinders, or a household hazardous waste event that specifically lists propane. Never puncture, cut, drill, burn, or remove the valve yourself.
Propane is the item where the wrong answer is genuinely dangerous, not just against the rules. A rusted 20-pound tank behind the garage still holds pressure years later. Here is where it can actually go, and the one thing you must not do.

Your Options, Start to Finish
1.Swap it at a cylinder exchange
Exchange programs at gas stations, hardware stores, and grocery stores take your old 20-pound cylinder when you pick up a filled one. It is the simplest legal route and it is designed for exactly this.
Exchange usually assumes you want another tank. If you are done with propane entirely, ask whether they will take the cylinder without an exchange, because policies differ by retailer.
2.Take it to a propane supplier
Propane dealers deal in cylinders all day, can tell whether a tank is still certifiable, and can properly retire one that is not.
Call first. Some accept only cylinders they filled, and some charge a small handling fee for a tank that is out of date or rusted past recertification.
3.Use a household hazardous waste event that lists propane
Pennsylvania DEP advises residents to check whether their local household hazardous waste program accepts propane tanks, and some Allegheny County events do.
Only if the event expressly lists propane cylinders, and follow their preparation instructions exactly. Do not turn up with a tank on the assumption that hazardous means everything hazardous.
4.Ask a scrap yard about its own conditions
Some scrap dealers will take a cylinder once it has been professionally emptied, depressurized, and rendered non-pressurized.
Saying it is empty is not proof a yard will take it, and the emptying and valve removal has to be done by someone qualified. This is not a route you prepare yourself with hand tools.
Why we do not haul propane, and who does
Propane is on our excluded list along with paint, oil, gasoline, and chemicals. That is not squeamishness, it is that pressurized flammable containers do not belong on a truck with furniture and cardboard, and licensed disposal for them runs through a different chain entirely. If we are clearing a garage that has a propane tank in it, we will tell you the tank stays and where to take it, and we will take everything else. A hauler who quietly tosses your cylinder on the load is doing you no favors.
One-pound camping canisters are their own problem
The little green 1-pound canisters that run camp stoves and torches are treated as pressurized propane containers too. They do not go in trash or curbside recycling whether they are full, partly full, or apparently empty, and they must not be punctured or crushed. Acceptance is also not the same as for 20-pound tanks: a program that takes barbecue cylinders may refuse disposable canisters, so ask about the specific type. Follow the product label and whatever the receiving program tells you.
How to tell if your tank is worth keeping
A 20-pound cylinder has a manufacture date stamped on the collar, and cylinders need periodic requalification to be refilled, so an old tank may be legally unfillable even though it holds gas fine. Check the collar before deciding. If it is within date and not badly rusted or dented, a refill is cheaper than an exchange and you keep the tank. If it is out of date, pitted, or the valve is damaged, retire it through one of the routes above rather than trying to get one more season out of it.
How to Dispose of a Propane Tank FAQs
Can I put a propane tank in the trash?
No. A propane cylinder must not go in household trash, curbside recycling, or an ordinary scrap bin while it holds propane or still has its valve attached, because the residual gas and pressure create fire, explosion, and processing hazards for waste handlers. This applies to a tank you believe is empty, because residual propane almost always remains.
Where can I get rid of a 20 lb propane tank in Pittsburgh?
The practical routes are a cylinder exchange program at a gas station, hardware store, or grocery store, a propane supplier that accepts used cylinders, or a household hazardous waste event that specifically lists propane tanks. Pennsylvania DEP advises checking your local household hazardous waste program first and otherwise looking for a local propane exchange company.
Can I empty a propane tank myself and scrap it?
No. Do not puncture, cut, drill, burn, or remove the valve from a propane cylinder. A scrap dealer may accept one only after it has been professionally emptied, depressurized, and rendered non-pressurized, under that yard's own conditions. Telling them it is empty is not enough, and doing the work yourself is how people get hurt.
What do I do with small camping propane canisters?
Treat the 1-pound canisters as pressurized containers. Do not put them in trash or curbside recycling at any fill level, and do not puncture or crush them. Ask the specific household hazardous waste event, propane retailer, or hazardous waste contractor whether they accept disposable 1-pound canisters, because that is a separate question from whether they take refillable 20-pound tanks.
Will you take the propane tank with the rest of my junk?
No, and no legitimate junk removal company should. Propane is on our excluded list along with paint, oil, gasoline, and chemicals. What we will do is clear everything else in the garage and tell you exactly where the tank goes. Call (412) 226-4500 and mention the tank so we can plan around it.
