If you have an old empty propane tank, you’re probably wondering how to go about throwing it away. However, because propane tanks contain a flammable gas, they can’t just be thrown in the trash with the rest of the garbage. Luckily, there are a number of convenient ways for you to safely dispose of, replace, or even refill your empty propane tank.

Handling Your Tank Safely

  1. Because propane tanks are pressurized, they can potentially explode when they’re compressed in a garbage truck. This means that not only is it dangerous to try to throw away your tank in the garbage, but most city sanitation departments won’t even pick up the tanks along with the rest of your trash. [1]
    • Some municipalities have exceptions to this rule for propane tanks under a certain weight. For example, empty propane tanks under 2 pounds (910 g) can safely and legally be thrown away in the garbage.
    • Check with your local city government to see if your propane tank can be safely disposed of in the garbage.
  2. There will still be a little bit of propane left in your tank even when it’s “empty.” This leftover gas can expand when it gets heated up, causing the tank’s safety valve to open and leak propane everywhere. Store your empty tank in a cool, shaded space until you’re able to have a licensed professional remove the leftover propane.
    • For safety, avoid storing your propane tank inside your home, in case a leak does occur.
    • Your propane tank needs to be stored somewhere where it will not reach 120 °F (49 °C).

  3. There will be a small amount of propane still in the tank that can be transferred over to a new tank for future use. However, it’s very dangerous to remove flammable gas from a pressurized canister, so hire a licensed professional to remove the gas, depressurize the tank, and remove the valve instead of doing it yourself. [2]
    • You can find a licensed professional to remove your leftover gas by contacting local propane suppliers in your area.

Reusing or Getting Rid of Your Tank

  1. Many propane retailers offer tank exchange programs in which you can bring your empty tank to one of their locations and have it replaced for a small fee. The cost for this type of exchange is usually around $20, which is a terrific price for not having to worry about throwing out the old tank yourself. [3]
    • The company you bought your tank from may even offer to come to your house to pick it up from you.
    • Some propane companies that offer a tank exchange program include AmeriGas and Blue Rhino.
  2. Many municipalities will have designated locations where citizens can bring hazardous waste that can’t be taken to a normal garbage dump. Contact your local government’s sanitation department to find out if there are any hazardous waste collections near you. [4]
    • Most municipalities will accept propane tanks that are up to 5 pounds (2,300 g) at hazardous waste drop-off sites. For tanks that are bigger than this, you’ll probably need to contact your local government about having someone come to your property to remove it.
  3. If your propane tank is refillable, you can refill it at any propane tank refill station at a cost of around $3-$4 a gallon. Your propane tank should have a label on it indicating whether or not it’s refillable. If you’re not sure, bring it to the refill station and ask an attendant if it can be refilled; chances are it can be!
    • Locations that include propane tank refill stations include AmeriGas and U-Haul.
    • Most single-use propane tanks are 1 pound (450 g) or lighter.
  4. If you can’t take your empty tank to a waste collection center and you can’t refill it, taking it to a scrap metal yard is going to be your best bet. Most scrap yards will take an empty propane tank, but call ahead to make sure your local scrap yard will take yours before you bring it to them. [5]

    No, it’s not a good idea to throw even a small, empty gas cylinder in the trash—and in many areas, it’s illegal. You’ll probably need to take them to a hazardous waste disposal center or a store that does recycling or trade-ins.

    Many hardware stores, such as Lowes and Home Depot, work with partners that do propane tank trade-ins or recycling. Call your local hardware or home and garden store and ask if you can return or trade in old tanks there.

    Attach the tank to a propane-powered appliance, like a grill or lantern. If you’re unable to get any flame, then the tank is likely empty. You can also weigh the tank if you know its tare weight (the weight of the tank when it’s empty) and have a propane tank scale.
