We had these nitrous oxide canisters dumped in our household green recycling bin a couple of weeks ago. It was right before it was due to be picked up, meaning the binmen (understandably) left it. We put in a request to the council to come pick them up but no luck.

Can they be taken to a recycling centre? We tried looking online but it wasn't clear. We didn't realise this was a thing, but I've now seen a few on the side of the road on the way to work.
