Recycling has been a big topic for quite a few years now, and in recent years it has become even more important. Although in itself it often requires significant inputs (both energy and often also material), it understandably also has advantages. On the one hand, it reduces the amount of waste that can be further used instead of being accumulated, and on the other hand, it reduces the amount of new materials that need to be obtained to produce new products (however, here is also a legitimate question, to what extent the materials for recycling are less burdensome than the material that is the output of recycling replaced). Canon Virginia, Inc. (CVI) has been recycling used toner cartridges from laser printers for years at its Canon Environmental Technologies (CETI) branch.
Individual parts are automatically separated and then travel to the respective departments. The plastic packaging is recycled into plastic pellets, from which a new cartridge is again manufactured. Canon does not recycle the metal parts themselves, they go to external partners who deal with it. What is new, however, is that residual toner can now also be recycled. It is the result of the Recycled Toner Pellet (RTP) project, when Canon teamed up with Basic Construction Co. several years ago to test whether its RTP could be used as a colorant and binder in asphalt mixtures. The tests were successful and Basic now buys 100% of all recycled toner from Canon. However, practical use was not so simple, because the novelty also had to be approved by the relevant authorities, namely the Virginia Department of Transportation (VDOT). This also worked out well after a few years, and now roads in Virginia can be manufactured with residual toners added.
