Recycle Used Stove Fuel Canisters

Fuel canisters run out pretty quick when you’re in the backcountry. If you’ve got old canisters with bad fuel or empty ones you wish to get rid off, it’s time to dispose of them responsibly.

3 Steps to Recycle Butane Fuel Canisters

1. Empty the Canister

The first and most crucial step is to ensure the canister is empty. To remove the gas from the canister, go outside or to a very well-ventilated room and use your stove to burn off the remaining fuel until the canister is empty. You will ensure safety for the next steps and also for the people who will eventually handle the recycling process and reduce the risk of accidents.

Some stoves lose performance when the canister pressure drops and it might be difficult to get rid of every last bit. Shake the canister and if you suspect that there might be some residual gas left in the canister, you can take a precautionary step to release it. Make sure that you’re well clear of any open flames or potential sources of sparks to maintain safety throughout the procedure. Connect your stove to the canister, turn it upside down, and then gently open the valve. This simple process will release the gas quickly. Once you can hear the hissing and the valve is open, just leave it open for a while. Even when the hissing stops, keep it open for a little while since there might still be some gas left inside.

2. Depressurize the Canister

Once you’re fairly certain that the canister is empty you should depressurize it. It is a fancy term for punching a hole into the canister. This is a mandatory step for recycling in most states. Make the puncture large and clearly visible, this lets people know the canister is empty, depressurized, and safe to handle.

Go and find a screwdriver, ice pick, scissors, or hammer and nails. Wear gloves to protect your hands if your tool happens to slip. To enhance safety and prevent sparks while puncturing, you can place a rag over the can before you start puncturing. This minimizes metal contact and friction, reducing the risk of igniting any remaining gas. Now go ahead and punch a hole into the canister. Once punctured, you can safely pack the canister in your bag for the remainder of your backpacking trip or transport it to a recycling center. There are special tools available, such as JetBoil CrunchIt, but regular tools, which most of us have in our homes, will work very well.

3. Deposit Your Canister

Recycling your used fuel canisters can be a bit of a challenge due to their classification as hazardous mixed metals. Many standard curbside recycling programs might not accept them, even if you’ve thoroughly emptied and punctured the canisters. This classification adds complexity to the recycling process, and it varies depending on your location. So, before tossing them into the bin, be sure to check your local recycling program’s policies.

If your curbside program doesn’t handle mixed metals, don’t worry. There’s usually a solution nearby. Some areas have specific collection days for mixed metals, or they offer drop-off programs at designated points. Keep in mind that lighter propane or butane cylinders are more readily accepted for recycling than their heavier counterparts, so consider opting for them when planning your camping or trekking trips. Not only are they easier to carry, but they’re also more likely to be accepted by your local recycling center.

Do not discard butane cans, even when they’re empty, in the regular garbage. Not only does this pose potential dangers, but it could also result in fines or other penalties.

Dispose And Recycle Propane Canisters

When it comes to used propane tanks, many grocery stores and home stores provide a convenient solution—reclaiming them and offering either refills or exchanges for full tanks. Another option is reaching out to your local propane supplier, who may have a program for handling used tanks.

For those looking to dispose of a tank, it’s often best to connect with your local household hazardous waste (HHW) collection site. However, keep in mind that regulations vary, and some municipalities may allow you to include empty propane tanks, cylinders, or bottles in your regular household trash. Before taking any steps, it’s wise to consult your local laws. Typically, they recommend emptying the tank, removing the regulator, and puncturing it to ensure it can’t be re-pressurized.

Dispose Alcohol

Alcohols like ethanol, methanol, and isopropyl, can usually be poured down the sink drain. Just make sure to start the water first to dilute the alcohol.

Check Your Local Options

If you’re having trouble finding a place to deposit your used canister then the safest bet is to contact your municipality and ask for advice. It’s also in their interest to help you recycle used cans. Usually one of the following ways will be available wherever you happen to be.

Household Recycling: Check with your local recycling center or municipality to see if they accept empty propane or butane canisters for recycling. They may have specific guidelines on how to prepare these canisters for recycling.

Specialty Recycling Programs: In some areas, there are specialty programs for hazardous waste disposal. Fuel canisters fall under this category due to their flammable nature. Investigate whether your locality hosts programs or collection events for hazardous waste disposal.

Metal Recycling Facilities: If your local recycling center doesn’t accept fuel canisters, you can contact metal recycling facilities in your area. Some may accept these canisters as scrap metal. Be sure to inform them that the canisters previously contained a flammable substance.

Household Hazardous Waste Facility: If no suitable recycling options are available, reach out to your local household hazardous waste facility. They can offer advice on proper disposal procedures and may have facilities for handling these items safely.

Why You Must Dispose of Pressurized Solvents Properly

Recognized as a hazardous substance by OSHA, the EPA, and other regulatory bodies, butane, being a flammable gas, demands careful handling from usage to disposal. The improper storage, use, and disposal of butane and similar solvents not only jeopardizes your safety but also poses environmental risks.

Safety Concerns

Stored under pressure, both butane and propane face an increasing pressure risk as the product degrades over time. During the collection process, these pressurized canisters could be punctured, leading to potential fires or injuries. Even a minor spark has the potential to ignite the canister, causing severe harm. Even after the can is emptied, residual traces of the gas can still ignite, resulting in canister explosions and the risk of fire.

Environmental Concerns

The burning of butane releases carbon dioxide (CO2) and often unburned hydrocarbons. While the environmental impact of unburned butane is generally minimal, the goal is to burn off most of the solvent before disposal, acknowledging the inevitable environmental impact. Improper disposal of butane and similar solvents can negatively affect local wildlife populations, with similar dangers applying to petroleum-derived fuel gases like propane. Ensuring proper disposal practices minimizes or eliminates the risk of combustion, preventing potential environmental hazards.”
