You can return your toner to Canon in the original packaging. They have a recycling programme at global.canon/recycle where you can print out GAS labels and send them back free of charge.

We recycle ours via the Swiss Red Cross service. Free of charge for us and the Red Cross apparently earns something from it: https://www.redcross.ch/de...

Danke Euch! (thumbs up)

Regional recycling centres accept toner for recycling free of charge.

Moin, waste disposal centres take the parts. Free of charge here. Greetings
