Hewlett-Packard Development Co. L.P. (HP) said it has increased the number of HP ink cartridges made with recycled content by 50 percent in the past year.
The Palo Alto, Calif.-based HP said in a news release that more than 75 percent of its ink cartridges and 24 percent of its Laserjet toner cartridges are now made with closed-loop recycled plastic.
HP uses recycled plastic from returned HP cartridges as well as plastic from other sources, including recycled plastic bottles and plastic apparel hangers, to produce new ink cartridges.
The electronic products maker said it has kept 566 million returned ink cartridges out of landfills since 1991.
