Camping Gas Cylinders Alternative ways to recycle Illegal in Garbage/Recycling & Drains Hazardous Waste Blue Line Transfer Gas cylinders can be brought to Blue Line Transfer Inc. for safe handling and recycling. Charges depend on size and weight of cylinder, and whether or not it is empty and at atmospheric pressure. Cylinders with a removed valve or puncture hole are deemed safe. Cylinders that have any gas and that are pressurized can explode and must be handled as hazardous waste. Use It Up If your cylinder isn’t empty, either use up the leftover fuel on your next camping trip, or simply run your stove or lantern until there’s no fuel and the flame dies out. Puncture Carefully Make your empty cylinder appear safe to sanitation workers by puncturing it carefully. Lever the sharp, triangular point of a can opener against the cylinder’s bottom rim, then label it with a permanent marker as “Empty” and “Punctured”. The AMC describes more ways to safely puncture an empty cylinder here. Don't Refill Disposables If your cylinder contains words like “nonrefillable,” “disposable” or “single trip,” do not try to refill it. Federal law prohibits the transport of refilled disposable cylinders because the metal is stressed to its capacity with its first use, and becomes thin and likely to explode when further stressed. Alternative Ways to Recycle Recycle in National Parks Yellowstone, Yosemite and Bryce Canyon National Parks all have propane cylinder recycling machines. If you are visiting one of these parks, dispose of your empty cylinder in one of their receptacles.

Disposable Gas Cylinders: A Huge Waste The United States consumes approximately 40 million disposable gas cylinders each year. These cylinders, both dangerous and expensive to recycle, mostly end up in landfills, taking up close to 5 million cubic feet of space annually. If recycled, 12,000 automobiles could be made each year with the recovered steel. Save Money with Refillable Cylinders When you buy a disposable cylinder, 80 percent of the cost is packaging. Not only are refillable camping gas cylinders good for the environment, they save customers an average of $320 over their 12-year lifespan, assuming the cylinder is reused 10 times a year.
