Obsolete dyes had always caused issues with their weight and bulk, quickly filling the skips to go to landfill and adding to the cost of waste removal. These are now also recycled; removed from our site by a licensed waste carrier and then processed into chippings. Until recently, the revenue generated from recycling has far and above paid for the cost for any hazardous waste removal or collection of waste to landfill. But although we currently receive no revenue (due to the current economic climate), we still continue to recycle.

Staedtler – the ecological pioneer Wolfgang Pöhlau, Director Business Unit Ink Jet at STAEDTLER Mars GmbH explains how the development of the company’s Lumocolor Jet Ink came about.

Although our intention was to be the trendsetter for a more environmentally friendly future, we could not anticipate that this ink technology would transform the mindset of the entire industry in such a profound way. But Lumocolor Jet ink technology was indeed a revolution, since we had proven that it is no utopia to develop water based inks capable of doing the ‘heavy jobs’.

When the first ink prototype was presented to the public in 2004, the working title, Lumocolor Jet ink was chosen, due to its similar characteristics to Staedtler’s top-selling Lumocolor pen, which enables the user to write on almost every surface.

Lumocolor Jet ink technology for industrial decoration In fact, the Lumocolor Jet ink technology with its impact on the industry is the latest step in our major ecological developments, which include multi-use cartridges, or ink bags, that dramatically reduce the amount of waste.

Lux meters measure light within the building and when the light is sufficient for the operators, any internal lighting automatically switches off. The company is even investigating the generation of a virtually paperless office environment, by making all documents accessible, throughout the Company, from a central location stored on the main computer server. Any rejected rolls of coloured vinyls are donated to local schools and community groups for use in creating artwork or generating costumes for carnivals and theatrical productions. KPMF constantly reviews current and forthcoming changes to legislation to determine the measures and methods that allow it to retain the highest standards of compliance. As Rob Musto says: “As a company, we try always to be proactive not reactive. By constant assessment of all aspects, we ensure that our environmental management makes a major contribution to our quality control – and that’s good for the bottom line, as well as the planet.” For further information visit: Xaar takes an environmentally responsible approach to the manufacture of its printheads. “Having achieved ISO 14001 status, we take clean manufacturing very seriously,” says Mark Alexander, Director of Marketing, “and our focus is on effective waste recycling.” Metal, plastics, glass and paper are all recycled, while methods of removing PZT in scrap printheads are currently being investigated. The use of solvents is closely monitored and collected solvent is recycled as a high-octane fuel for producing

and re-circulates ink instead of spitting when idle. “These are small elements but quickly make a difference in terms of cutting costs and waste,” explains Mark Alexander. “Energy saving too is a factor. Printheads are low energy/high efficiency components, which is becoming increasingly significant.”

Ultimately, when compared to traditional process of off set/flexo printing, inkjet printing is a ‘greener’ process. Start up waste paper is minimal, there are no plates or blankets to be disposed of or cleaned and you can print exactly what you need ‘to order’. For further information visit:

Corporation set out several basic ecological principles. One of these was the development of products comprising recyclable parts. An optimal result was achieved in this regard, with the launch of the SP range of large format printers, which feature parts that are 97 percent recyclable. In 2007, Roland DG Corporation introduced its own Environmental Label based on the standards stipulated by ISO 14021 for Type II environmental labelling. This certifies that the company helps to prevent global warming by using recylable resources, helping to increase environmental awareness and providing information on the environmental aspects of its products. All products released after the introduction of the EcoLabel are built in accordance with these internal standards.

The Libramatt LIM series, introduced in 1997, fulfilled the need for a matt ink series and in 1999, Libraprint LIP reflected the increasing need for speed, by offering faster drying times. Last year the LIBRA family expanded once again, with the launch of Librastar HF, for industrial print applications. Librastar HF is the first ink to meet the demands of the electronics sector and incorporates halogen-free raw materials, such as a PVC-free binder and unchlorinated pigments. It is suitable for use with both screen and pad printing and for one or two component applications. Marabu is fully sensible of the need to combine environmental benefits with high performance for demanding applications

GREEN CREDENTIALS and Librastar HF fulfils both of these aspects. It corresponds to the demands of RoHs; the Canadian Hazardous Products Act, DIN EN 71/3 and sets the benchmark for halogen-free ink design. Another new UV ink, Ultraglass UVGCC was recently showcased at the new Nutec Exhibition in Frankfurt and was also accepted by Material ConneXion®(materialconnexion. com), the leading global platform for material solutions and innovations. For further information visit: As one of the leading providers in the graphics sector, Neschen recognised the trend towards greater green awareness some time ago and consistently uses green production processes and materials. For example, its Pro Nature product, which is subjected to the most stringent internal norms and checks, is a result of this, but as Neschen’s Frank Seemann, Head of the Marketing and Communications Department at Neschen AG in Bückeburg, Germany points out: “ Pro Nature is not just a label for the customer – the advertising materials for this line are made exclusively of environmentally and resource-friendly materials. One of these is cotton – a natural fibre that is not just pleasantly warm and soft, but also kind to the skin. So it goes without saying that cotton is becoming

It has also been a green pioneer and its continuing commitment to top-level research and development will ensure it continues to break new ground in the future.” For further information visit:
