Disposal of Propane Gas Tanks
- 1). Open the valve on the tank and attempt to light the grill, if the tank is still connected. This will make sure that all of the gas has been used in the tank.
- 2). Take the old tank to a tank supplier, such as Home Depot or Lowe's or your local gas station. Many tank suppliers will allow you to trade in your old tank when purchasing a new one--the cost for a new tank is often significantly less when you turn in an empty tank.
- 3). Check with the local municipality or city to see if there are any local collection or household hazardous waste programs available for old propane tanks.
- 4). Contact a local scrap metal yard and see if they take old propane tanks. According to Earth 911, you should remember to bring the valve with you as the brass it is made of is more valuable than the steel.
- 5). Dispose of small 16.4 oz. propane tanks, such as those used for camp stoves, in your household trash. According to Coleman, you must first make sure the tank is entirely empty by running the appliance to which it is attached until the flame goes out. After the tank cools, it can be safely thrown away.
