Braintree accepts propane tanks at our Recycling Center (for Braintree Residents only).
Propane tank retailers take back refillable tanks. Scrap metal dealers accept propane tanks in any condition.
Helium and CO2 are inert, so the valves of unwanted tanks should be opened to relieve the pressure. Tanks may be disposed of with scrap metal or brought to a scrap metal dealer.
Ethylene & Other Pressurized Flammable Gas Cylinders
Ethylene and other pressurized flammable gas cylinders are not accepted with scrap metal or at hazardous waste collections. Contact your local fire department for instructions on their proper disposal.
