Recycling Used Cartridges
The Clean Earth Campaign
●THE Canon CARTRIDGE RECYCLING PROGRAM
The Canon Cartridge Recycling Program fulfills the first initiative of Canon’s Clean 
Earth Campaign, which supports four critical environmental areas:
●Recycling in the Workplace
●Conserving Environmental Resources
●Scientific 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.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 landfill waste. Complete details concerning this program 
are enclosed in each PC Cartridge box.

Maintenance
Since its inception, The Canon Cartridge Recycling Program has collected millions of 
cartridges that otherwise would have been discarded into landfills 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 significant contribution to a cleaner planet.
●Cartridges collected through this program are not refilled.
●You are not entitled to a tax deduction or rebate for the return of empty cartridges.
