Question

Accepted Answer

Recycled Ink Cartridges Yield Metals and Plastics for New Products

Used ink cartridges collected through Canon Hong Kong's recycling program are dismantled, with their constituent metals and plastics being processed into raw materials for the manufacturing of other products. This initiative forms part of Canon's broader commitment to environmental conservation and sustainable development, aligning with their corporate philosophy of "Kyosei."
Ink Cartridge Recycling Program Details

Since its inception in 2009, the "Ink Cartridge Recycling Program" has actively involved primary and secondary schools across Hong Kong. In partnership with the local cartoon character McDull, who serves as the program ambassador, the initiative aims to cultivate environmental awareness among the younger generation. The program has seen widespread participation, with over 300 organisations, including housing estates, shopping malls, supermarkets, and schools, setting up collection boxes for used inkjet printer cartridges of all brands.
Environmental Education and Outreach

To further enhance students' understanding of environmental issues, Canon Hong Kong has organised more than 230 environmental seminars for participating schools. These seminars have reached over 70,000 students, disseminating messages about recycling and sustainable development. As of June 2026, the program had successfully collected over 295,000 ink cartridges.
STEAM Workshop Component

In addition to the recycling efforts, Canon Hong Kong also conducts a "Build Your Own Camera" STEAM parent-child workshop. This activity allows participants to assemble handcraft camera models, fostering an understanding of basic optical principles and the science behind imaging. The workshop aims to provide an engaging and creative learning experience, complementing the environmental education goals of the ink cartridge recycling initiative.
