Propane Tanks and Cylinders
Propane tanks and cylinders are considered hazardous waste and should not be disposed of in your regular trash. Before disposing of propane tanks or cylinders, first consider exchanging them instead. Many propane suppliers and retailers offer exchange programs where you can trade in your empty tank for a full one. This is a convenient option if you use propane regularly and have a spare tank on hand.
If none of the above options are available, some WM landfills, transfer stations and recycling centers are equipped to properly dispose of propane tanks.
