Program Information
Since 1990, the HP LaserJet Toner Cartridge Recycling
Program has collected more than 25 million used LaserJet
toner cartridges that otherwise may have been discarded in
the world’s landfills. The HP LaserJet toner cartridges and
consumables are collected and bulk-shipped to our
resource recovery partners who disassemble the cartridge.
After a thorough quality inspection, minor, nonprinting
process critical parts such as nuts, screws and clips are
reclaimed for use in new cartridges. Remaining materials
are separated and converted into raw materials for use by
other industries to make a variety of useful products.
