According to Plastic Oceans, half of all plastic produced is for single use, meaning it is used for only minutes and then thrown away. That's 380 million tons per year. This is why HP has engineered their Original HP Ink Cartridges to be made of both recycled ocean-bound plastic bottles and recycled HP Cartridges. Download this brochure, "Use of recycled content" from HP and Sandia Computers. It describes what HP is doing to reduce, reuse and recycle to help save our planet. Included on the brochure is a detailed listing of the amount of recycled plastics HP uses in each of its Original HP Ink Cartridges.
