Which bin for gas bottles and camping gas?
Usual answer in the UK
Special Special collection or specialist disposal
Gas cylinders must never go in a bin. Return them to the supplier or ask your tip whether it accepts them.
Also possible: Household waste recycling centre (the tip).
Does every council do this?
Most councils follow the answer above, but bins and sorting rules are set locally, and a few councils still do things differently. If your bin has a sticker, or your council sent a leaflet, follow that. Enter your postcode to go straight to your council's guidance.
