A-Z Recycling Guide -- Propane Canisters
If a propane canister's certification has expired, it can be brought to various sites to be "recertified" for 5 years (at a time) until it is completely unusable. In order to be recertified, the tanks or containers must be in good condition with no excessive rust or damage; they can be then taken to various other locations listed below for recycling.
Propane tanks are NOT accepted at CHaRM (Center for Hard-to-Recycle Materials) in Boulder.
