Recycling Printer Cartridges recover valuable materials such as metals, plastics and inks for reuse. This in turn prevents potential contamination of the environment from chemical leachates.

It takes about three litres of oil to make a laser cartridge and a cartridge can be remanufactured three or four times. All parts of a cartridge replaced in a remanufacturing process can be recycled, and greenhouse gas emissions are reduced on average by 4.5kg for every laser cartridge manufactured.
