HP gives new life to used printer cartridges

HP has introduced a new process that manufactures new cartridges from recycled ones, separating and rebuilding them from scratch.


HP has introduced a new process that manufactures new cartridges from recycled ones, separating and rebuilding them from scratch.

The "closed loop" process gives used HP inkjet cartridges a sustainable end-of-life value and puts the material back to good use while being environmentally friendly, HP representatives said.

The process first breaks down plastic in printer cartridges made of PET (polyethylene terephthalate), after which additives including fibres and resins are used to strengthen and regenerate the plastic. The remoulded plastic is then used to manufacture new HP inkjet cartridges.

HP said the plastics or cartridges are not melted, refilled, resold or sent to a landfill. The process also applies to other products, such as PET water bottles.

The process, which went into pilot in 2005, has already resulted in HP manufacturing 200 million printer cartridges, said Scott Canonico, manager of environmental policy and strategy for HP supplies.

Each inkjet cartridge contains 70% to 100% recycled material. Users will find the process beneficial as cartridges with new material perform better than used or refilled cartridges, Canonico said.

HP allows users to return inkjet cartridges worldwide for free in most cases through its recycling programme, according to Ken Fleming, marketing director of supplies for HP. In some cases, a postage-paid return envelope is provided by HP with the inkjet print cartridge box.

The process will apply only to HP cartridges, the company said. No external inkjet cartridge brand is being put through the new recycling process, Canonico said.

Before the implementation of the new process, not all plastic recovered went into making new cartridges, Canonico said. They were used by others to manufacture products including auto parts and toys.

The company said it had already recycled 1 billion pounds in weight of hardware and it hopes to recycle 2 billion [B] pounds by 2010. HP offers recycling options for hardware including PCs, mobile phones and computers.

The inkjet cartridge recycling initiative is the latest in HP's broad effort to be environmentally friendly. HP recently announced that it would implement more energy-efficient technologies across its PC lines to reduce computer energy use by 25% in 2010.

Recycling is one way to go green, Canonico said. "We're always looking to further our commitment to customers and our commitment to the public and environment," Canonico said.

While achieving the closed loop process was an achievement, HP will continue to look for new ways to better recycle products, Canonico said.
