Disposing of Unused CO2

[Tippsy-Turvy]

Anyone with a smart way to empty a CO2 cylinder with a minimal environmental impact?

 

[Barbarossa]

Plant a tree.

Just empty it. The environmental Impact will BE minimal.

Hold on, that stuff is dangerous, but I'll volunteer to safely dispose of it. I'll use it to carbonate kegs of beer and then it will be released very slowly, one pint at a time.
When can you send it over?

If you used it for beer, it'd still be in the environment. Your body just blows off by respiration, any of the CO2 you put in it. Whether it's the stuff you put in your stomach or the gas some GI doctors use now when you get a colonoscopy.

Mine used CO2 instead of air on the last photo session of my insides. Absolutely no bloated feeling or farting when I got off the table.

Oh boy, this thread escalated qucickly!

Bury it.
In a hole.
In the ground.
Very deep.
Plant a tree over it.

Send it to NASA:

"...NASA has developed a new technology that can convert the greenhouse gas carbon dioxide (C02) into fuel by using solar-powered, thin-film devices..."

Or

Make your own diamonds:

"...The “green technology first” uses carbon dioxide captured directly from the atmosphere to form the diamonds – which are chemically identical to diamonds mined from the earth – using wind and solar electricity, with water collected from rainfall...."

Why empty the tank ? Leave it in the tank , it doesn’t go bad .

Why do you want to dispose of it?

 

[DuncB]

Technically you can't dispose anything unless you can get it off planet, you are just moving it around!
