How do I dispose of old propane tanks?
There is a website for the Massachusetts Department of Environmental Protection (DPE) that has good information on this. Go to http://www.mass.gov/dep/recycle/hazardous/propane.htm and you will find a listing of vendors who can take 20 pound tanks. Smaller 1 liter tanks, such as those used for household torches, can be disposed of in the trash when empty.
