Closed Loop Program By HP

When you have used up the ink on your printers, the immediate instinct is to replace them. But what do you do with the old one? Throw them to the nearest garbage can? Thanks to the efforts of Hewlett Packard, you can do your share for joining their vision of recycling used cartridges.
Called the closed loop process, the used cartridges are not melt, refilled or placed in a landfill. They are recycled and made part of the new line of production, plastic of which is their usual casing.
The process first breaks down plastic in printer cartridges made of PET (polyethylene terephthalate), after which additives including fibers and resins are used to strengthen and regenerate the plastic. The remolded plastic is then used to manufacture new HP inkjet cartridges.
So if you have a used up cartridge, set it aside. Send it to HP and you are doing the world a favor as well.
