Green Cartridge Company was founded in 2004, by two Hewlett Packard veterans, to bring leading edge quality processes to the replacement printer cartridge industry.  Green Cartridge has taken up the challenge to help solve a huge environmental problem – what to do about the millions of ink and toner cartridges that end up in Colorado’s landfills. Coloradans sent 5 million ink cartridges alone into landfills in 2007 – that’s one for every man, woman and child in the state.
