It is possible to refill ink cassettes, and it often turns out to be cheaper than buying new ones. Empty ink cassettes can be sorted into a bin for burnable waste. Unused ink is hazardous waste, so it has to be taken to a hazardous waste reception site.
Sorting guidelines:
Sort both recyclable waste and hazardous waste separately.
Keep different hazardous wastes separately from one another. Store in original packaging or mark the contents of the container. Outdated medicines can be returned to a pharmacy, and used batteries can be returned to the store.
Waste reception:
Own waste bin, Condominium waste bin, Recycling centre, Waste treatment centre, Sorting station
