Some hazardous waste disposal sites or local public works departments may take your tanks, while others recommend calling a propane supplier. Remember – it’s never OK to put propane tanks of any kind in garbage bins for curbside trash or recycle services.
How do I get rid of little green propane tanks?
To dispose of smaller tanks that are damaged or unserviceable, contact a propane supplier, or your local household hazardous waste collection site. Some municipalities or local regulations may allow for disposal of empty propane tanks, propane cylinders, and propane bottles with your regular household trash.
