They have expiration dates, after which you cannot refill them with propane. But, you can buy an air kit and turn them into portable air tanks.

Remove the valve, fill with water and drill a hole below the water line and take to a scrap metal yard and they should take them as normal scrap metal.
That is what our local yard tells their customers to do. With two holes for air circulation there is no chance of retained gas to explode if compressed or exposed to pressure.

And drilling into them isn't going to be potentially dangerous? I guess the heat generated wouldn't be high enough, and sparks are unlikely. If "I guess" and "unlikely" are good enough safety measures for you, then drill away. :D

If it's full of water there isn't going to be any vapors to ignite.

Take them to a rifle range, place them down range and shoot one. Then act innocent when the bomb squad shows up. "Officer, I saw a rock downrange and shot it just for fun. It blew up!"
Unfortunately, when shot with a firearm, they don't blow up. :(
There are smaller refillable cylinders that the plumbers use to fuel their turbo torch's. be sure to get the propane not the mapp cylinder
They look to be 1 to 1-1/2 gal. (4 to 6 lb).
Can be found at a good plumbing supply or sometimes a welding supply.

I have a small Webber cooker that uses the small propane tanks. My problem is, where do you dispose of them? The local landfill wants $5 apiece to take them. I don't think I even paid $5 each for them! I use the small ones because I can't lift the 20lb tanks anymore (4 back surgeries). Would love some ideas as to what folks who use these tanks for welding do with them after they are empty. Thanks ;-)
Took my old outdated tank to a place that does exchanges and for a small upcharge they gave me a new tank full of propane. It is so much for a refilled tank and they charged me a few dollars more for the exchange. Much cheaper than buying a new tank. They will then re-calibrate them and check for leaks, etc. This was the 20lb tank though. But the real small one that are 1 lb. Just put mine buried in the garbage and no problem.

Well I used to know a guy who did it all the time. Of course he was using a 50 cal rifle with tracers. (no he didn't live here in California)

Best idea, do it all the time. :thumbup: :thumbup: :thumbup:

While this is a good idea it does not sound like a good idea for you. I also do it and therefore do not throw many away. But you have to extremely careful and know what you are doing. Be careful. Be careful. Be careful.
Just checked Amazon and they sell a refillable 1 lb unit but are quite expensive. But one's safety is worth more than a few dollars.
If you're talking about the one pound, usually green containers be especially cautious. I would not try removing any valves or drilling any holes because even a very small amount of propane could be devastating. Check with your, or a nearby city for hazardous material collection points. They know what to do with them. Save up till you get a few to make the trip worth it and take them then. The one near us doesn't charge anything because they don't want a fee to cause anyone to put them in their regular trash or recycling. Even when you think they are empty, they really aren't, they just don't have enough pressure to force the gas out. Good luck.
My land fill will not take fluorescent light tubes. A year ago I took a bundle of maybe 20 of them with me to walmart and told the manager and asked what I was supposed to do with the tubes I bought there, he said bring them in. I am sure they just put them in the compactor with the rest of walmart trash.
I like your answer to that one
Take them to Home Depot where they can be recycled or refilled. I've also heard that Walmart, Lowes, Albertson's, SafeWay, Tom Thumb do the same but I'm not sure.
Just list as curb alert on Craigslist in the "Free" section.
