How do you recycle propane cylinders small?
I have two Coleman propane tanks that were used to empty a small scale camping. Is there a way to recycle? If yes, what should I do?
Check with your garbage service or local recycling facility. Must have Household Hazardous Waste Program, or something. Check whether the type that can be filled or not, if so you can refill and use them again. I have seen places like gas stations where you fill the large reservoirs, which have a place to recycle old too.
