A: Propane is flammable. Most waste and recycling facilities will not accept an old propane tank because it’s considered hazardous waste. That makes disposal a little more complicated than throwing out the pizza box from last night’s dinner.
In some cases, the tank can be recycled or exchanged. If you have a propane supplier nearby, the tank can probably be refilled. However, propane tanks do have limits to how many times they can be recycled and refilled. Used propane tanks damaged by corrosion, dents, or use require proper disposal, and it’s important to understand how to get rid of propane tanks properly.

A used propane tank that is still in good condition can be exchanged at a designated retailer, where you leave your empty tank in exchange for a full tank. Many propane supplier companies have exchange depots outside of local and chain hardware stores, gas stations, and convenience stores. Many of these depots are self-serve, 24 hours a day, 7 days a week.
Depending on the supplier and location, you may have to pay a fee in the store or at a kiosk. It depends on the company and location, but either way, the empty tank stays at the depot, and a full tank of equal size goes home with you.
Tanks that are past their expiration date, damaged, rusted, or otherwise no longer usable cannot go to a standard recycling center. They pose a safety hazard because of the potential for residual propane still left inside the tank. However, they can go to a specialized recycling center with the equipment and employees trained to completely drain old propane tanks.
If you’re not sure where to find a specialized recycling center, contact a local propane supplier. They can often direct you to locations in the area that accept and handle hazardous materials like an old propane tank. City government websites may also include information on where and how to dispose of old tanks. Do not try to sneak a propane tank into the regular recycling to curbside garbage because lingering propane can explode or combust under pressure or when exposed to excessive heat.
Large permanent tanks require more assistance to recycle. In this case, contact a local propane supplier. They have the equipment necessary to safely remove, dispose of, and/or replace large household propane tanks. If you’re unsure if the tank needs replacement, suppliers can also inspect the tank and provide an assessment of its condition.

If you’re not sure how to dispose of propane bottles or small tanks, like those used for camping and small portable heaters, think of it as a smaller version of a larger tank. It may be small, but it can still contain dangerous residual propane. When they’re no longer usable, take them to a hazardous waste collection site. A propane supplier, hardware store, garbage disposal service, or recycling center may be able to direct you to the closest location or provide additional information about how to dispose of a propane tank.
