HP expands environmental sustainability initiatives with HP Indigo
HP continues to demonstrate its leadership and commitment to environmental responsibility in the printing industry with the announcement of developments that help reduce the environmental impact of HP Indigo digital prints.
Updates include new trials that conclusively demonstrate the deinkability of HP Indigo prints in typical graphic arts paper deinking mill configuration; fully recyclable packaging for ink cartridges; expansion of its take-back program for recycling consumables; and reduction of the HP Indigo carbon footprint.
Over the last few years, HP has collaborated with a range of industry and academic deinking experts to gather lab-scale, pilot-scale and mill-scale deinking data that verify HP Indigo prints can be deinked in a typical graphic arts paper deinking mill configuration. HP Indigo prints are now fully recyclable and can be placed in normal recycling collection.
In June 2013, Voith Paper, a leading supplier of deinking equipment, and the Paper Technology Department of PMV Darmstadt, a leading German technical institute, conducted two pilot-scale trials with 5 percent and 10 percent HP Indigo feed. The research found that even with 10 percent HP Indigo feed, the pulp produced in the trials was suitable for standard and higher quality graphic arts recycled paper grades.
“These pilot plant trials have convincingly demonstrated the deinking ability of HP Indigo prints using standard 2-loop deinking processes,” said Jürgen Dockal, product development engineer, Voith Paper Ravensburg Fiber Systems Technology Centre. “Proven equipment and standard deinking chemistry can be used, and parameters such as brightness development, ash content and yield are unaffected by the presence of up to 10 percent Liquid Electro Photographic prints.”
PMV-Darmstadt has also made significant progress in developing a lab scale 2-loop test that correlates with the Voith Paper pilot trial.
These results complement two previous full-scale mill deinking trials, which were conducted in collaboration with Arjowiggins Graphic at its 3-loop Greenfield deinking mill in Chateau-Thierry, France (pictured) in November 2011 and October 2012. In the mill-scale trials, 5 percent HP Indigo Liquid Electro Photographic prints (LEP) were added to the standard mill furnish. In both cases, high-quality deinked pulp was produced with outaffecting mill process efficiencies or operating parameters.
“The results of the pilot-scale trials show that printed paper from HP Indigo digital presses is compatible with typical graphic arts deinking mills even at levels higher than what likely would be encountered,” said Roy Eitan, director and general manager, HP Indigo and Inkjet Digital Press Solutions, Graphics Solutions Business, HP Asia Pacific and Japan. “Along with results from the Arjowiggins deinking mill trials, these latest results show that HP Indigo users can continue to feel confident that HP Indigo prints can be recycled back to high-quality graphic arts papers.”
As a part of HP’s ongoing commitment to environmental sustainability, HP Indigo has introduced improved ink cartridge packaging for the HP Indigo 6000 and 7000 series digital presses. The new cushioning tray is made of 100 percent recycled, moulded pulp and is 100 percent recyclable. Users can now dispose the cushioning tray with the ink cartridge’s cardboard box.
HP’s free take-back program for HP Indigo supplies for customers across Asia Pacific has now been expanded to include series four binary ink developer (BID) base and BID roller used in the HP Indigo 10000, 20000 and 30000 digital presses.
In addition, HP continues its program to offset carbon emissions associated with the manufacturing and integration of the new generation HP Indigo digital presses. HP Indigo supports projects globally in the community that offset the net contribution of carbon emissions from the manufacturing process. As a result, all HP Indigo series three and four presses are manufactured carbon neutral
