Canister style camp stoves are convenient, easy to use, and a popular choice for many backpackers. They are fueled by single-use gas cylinders filled with a mixture of isobutane and propane, and one major problem is that these fuel canisters can end up in landfills. This guide will explain how to recycle camp fuel canisters to keep them out of the garbage.
Before a fuel canister can be recycled, it must be completely emptied of all flammable gas. A quick and easy way to ensure your tank is completely empty is to attach it to your camp stove and open the valve. Make sure to do this outside, and leave the valve open for a few minutes so all the pressurized gas can escape.
Recycling facilities need to know a fuel canister is empty before they can process it into steel scrap. A tank with multiple holes large enough to see through leaves no doubt that it is completely empty, and recycling facilities will not process fuel canisters unless the holes are clearly visible.
A pry-style can opener works well to punch holes in canisters. Another method is to use a large nail and hammer. Avoid using an angle grinder, band saw, or firearm that may create a spark—in case any flammable gas remains in the tank.
Make sure your curbside recycling program accepts mixed metals. If they don’t, then find a metal recycling facility in your area that accepts drop offs. Many backpacking destinations and national parks have special fuel canister receptacles near trailheads or dumpsters.
Gas canister backpacking stoves are convenient, reliable, and easy—so anyone can be a chef in the backcountry. With a few simple steps, you can make sure your spent canisters are repurposed to make steel instead of just going in the trash or sitting in your gear closet.
