I have a number of old gas canisters commonly used in camp stoves.
- They have been around for over 5 years and have rusted - that is to say their condition is questionable.
- They are all 80% butane, 20% propane (my single burner camp stove claims it can take butane only)
- Some are half full, others are completely full
I asked the local council but even after ringing other departments all they could tell me is that they should not go into my regular/recycling bin.
I asked the local dump, but they told me that they must be empty first. They also said that there are places where you can empty gas cylinders (for BBQs, etc) but didn't know any place that could/would empty camp stove canisters.
I asked a couple outdoor shops (BCF, etc), but the only suggestion I got was to manually release the gas myself. My concern is that releasing 4-5 full canisters of gas into my back yard would be too dangerous.
How do you safely dispose of these old and rusty camp stove gas canisters? I am in Australia.
