Single-use compressed gas cylinders are commonly used for camp stoves, welding, filled with flammable propane or butane. Damaged or empty gas cylinders are hazardous waste and should never be put in the garbage or recycling. They could become punctured during the collection process and cause a fire or injury.

Old, rusty or unknown cylinders may be taken to a scrap metal company once they have been completely emptied with the valves safely removed. Companies that specialize in gas cylinders may offer this service or have additional disposal suggestions. As possible, take it back to where you got it or have the supplier come pick it up. For situations other than common fuels, contact a hazardous waste pick-up hauler.

Bring home empty single-use gas containers from camping or tailgating for proper disposal. Consider switching to refillable camping gas 1lb cylinders. Go to RefuelYourFun.org for details and locations.
