Which bin for printer ink cartridges?
Usual answer in the UK
Take-back Shop or take-back point
Ink and toner cartridges can be returned to the manufacturer or to shops and charities that collect them.
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.
