 Recycling Used Cartridges 
Canon has instituted a worldwide recycling 
program for cartridges called “The Clean 
Earth Campaign”. This program preserves 
precious natural resources by utilizing 
a variety of materials found in the used 
cartridges that are of no further use, to 
remanufacture new cartridges which, at 
the same time, keeps the environment 
cleaner by reducing landfi  ll waste.
Complete details concerning this program 
are enclosed in each Cartridge box.
The Clean Earth Campaign
THE Canon CARTRIDGE RECYCLING 
PROGRAM
The Canon Cartridge Recycling Program fulfi   lls the fi rst initiative 
of Canon’s Clean Earth Campaign, which supports four critical 
environmental areas:
• Recycling in the Workplace
• Conserving Environmental Resources
• Scientifi   c Research and Education
• Encouraging Outdoors Appreciation
The remaining “Clean Earth” initiatives are supported in the 
U.S. through sponsorships of the National Park Foundation, the 
National Wildlife Federation, and The Nature Conservancy and in 
Canada through donations to the World Wildlife Fund Canada and 
The Nature Conservancy of Canada.
Since its inception, The Canon Cartridge Recycling Program has 
collected huge amount of cartridges that otherwise would have 
been discarded into landfi   lls or similar facilities. 
Instead, this rapidly growing program returns used cartridges to 
the manufacturing process, thus conserving an array of resources.
Becoming a part of this worthwhile program is easy. When your 
cartridge is of no further use, simply follow the instructions 
detailed for U.S. or Canadian residents. We appreciate your support of The Canon Cartridge Recycling 
Program.
Working together we can make a signifi
  cant contribution to a 
cleaner planet.
• Cartridges collected through this program are not refi  lled.
• You are not entitled to a tax deduction or rebate for the return 
of empty cartridges.
