I'll have to find out what happens to empty CO2 capsules at our club. There always seems to be a lot of them either lying around or in various containers. It always appeared a shame that they couldn't be recycled for refilling for re-use but I would imagine the cost would be prohibitive?

Incidentally, I wonder why there is such a significant difference in price between brands? Steel and CO2 prices & manufacturing costs must be about the same - I guess that they are probably all made in China?
