It is estimated to take from 450 to 1000 years for a printer cartridge to break down in landfill.
When purchasing a printer, consider its print cartridge usage.
Consider if you really need that printout, or can read your documents on-screen.
Reduce the need to buy new ink cartridges by having them refilled by a reputable agent.
Use draft-mode printing to save ink where practical.
Cartridge World and Warehouse Stationery recycle ink cartridges locally.
There is a small wheelie bin for recycling ink cartridges at the Whanganui Resource Recovery Centre.
Please keep from landfill wherever possible.
