Most retail stores that sell 20 lb. (gas grill size) propane tanks offer free exchange programs to get a new filled tank. Blue Rhino also offers a free recycling program for 20 lb. tanks that are no longer needed. Write “RECYCLE” on the tank and take it to any Blue Rhino location.
Smaller tanks are often not refillable but can be recycled at SWACO’s permanent Household Hazardous Waste facility.
Propane tanks should never be put in your curbside or drop-off recycling container. Even when they seem to be empty, they can retain enough propane to cause an explosion and put recycling workers at risk.Find Recycling Locations Near You
