Due to the relatively small volumes of ink that are disposed and the leachate controls present in engineered landfills, minimal environmental impact to a water supply is expected from releases from HP Ink cartridges disposed in landfills.

To minimize even further the possibility of such an event, we encourage our customers to recycle their cartridges for free via the HP supplies take-back program. More details on available options per country is available at http://www.hp.com/recycle
