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.

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: www.kpmf.com 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.

Ultimately, when compared to traditional process of off set/flexo printing, inkjet printing is a ‘greener’ process.

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.

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.

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.

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.
