Yep, I save all If mine and when I take on my empty cans for scrap money I also then on my empty co2 cartridges.

I normally stick them in the ground when I'm out plinking with kids at different ranges for them to shoot. Then put them in the recycling full of dents. It's good target practice for the boys and makes a change from cans, bottles and little black dots on paper stapled to a piece of wood!

My scrappy said they won't take them, in case they explode. I told him I'd only bring the empties, but he was adamant.
I'll ring other scrapyards, but it's a bit frustrating so far, as I have half a bin bag full.
