print cartridge recovery
Customers interested in recycling their genuine HP print cartridges can participate in
HP's empty print cartridge return and recycle program. HP offers this program in the
United States, Puerto Rico, France, Germany, and Singapore, more countries than any
other print 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 request postage-paid return envelopes or bulk boxes via the
Web at www.hp.com/go/recycle. Customers will be asked for their name, phone
number, address, and how many bulk boxes or envelopes they would like. Postage-
paid envelopes and/or bulk boxes will be shipped within two days.
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.
Returned cartridges are separated for purification into raw materials for use in other
industries to manufacture new products. Examples of products made from recycled HP
print cartridge materials include automobile parts, trays used in microchip fabrication
processes, copper wire, steel plates, and the precious materials used in electronics.
Depending on the model, HP is able to recycle up to 65% of the print cartridge by
weight. The remaining parts that cannot be recycled (ink, foam and composite parts)
are disposed of in an environmentally responsible manner.
