Until very recently, it was impossible to recycle those old canisters for the simple reason that nobody wanted to risk having the gas left in them blowing up or starting a fire. But now—good news for campers—you can heat up the pasta sauce at your campsite and enjoy it even more. Coleman, a major manufacturer of canisters, has introduced a “Green Key” canister. The green key that comes with the canister allows you to make sure all the remaining gas is expelled, thereby averting disaster and making it safe to recycle. To find the nearest recycler that takes them, go earth911.com, follow their instructions, typing in “steel” and your ZIP code.
