12.3 Print cartridge recovery
Customers interested in recycling their genuine HP print cartridges can participate
in HP's Planet Partner's Program for inkjet cartridges. HP offers this program in more
countries/regions than any other inkjet cartridge manufacturer in the world. This
program is provided as a free service to HP customers as an environmentally sound
solution for these products at end-of-life.
To participate, simply follow the directions provided on the HP Web site at this
address: www.hp.com/recycle. This service is not available in all countries/regions.
Customers may be asked for their name, phone number, and address.
Because HP's unique recycling processes are very sensitive to material
contamination, we cannot take back and recycle cartridges from other
manufacturers. The end products of the recycling process are used in the
manufacture of new products, and HP must ensure the composition of the material
is consistent. To do that, we recycle only HP original cartridges. This program does
not extend to refilled cartridges.
