ImageWelcome to Verdigris. This site provides information about environmental initiatives for the international printing community. It has a range of articles and reference links for printers, publishers, technology providers and anyone else who’s interested.

Articles cover all sorts of topics from explaining the basics of carbon footprinting for printers, to describing how individual printing companies are doing their bit to minimise their impact on the envrionment. This is an educational site that includes reference material and links to industry associations and environmental organisations around the world.

Standardising Energy Consumption of Digital Printing Devices

Within our ISO working group we are looking at a document Fogra has drafted to provide guidance for quantifying how much energy a digital printing device consumes. You would think that this is pretty straightforward, but it’s not just a matter of counting how many units of electricity a digital press gobbles up. The idea would be to provide a means of accurately capturing comprehensive energy consumption data consistently, from device to device.

Carbon Footprints a Lighter Tread

For many years the graphics industry has been doing its bit to minimise carbon footprints, mostly because cutting waste saves money and time. But whatever the motivation, together with other industries we may be helping to make a difference. The International Energy Agency (IEA) reckons that global efforts to mitigate climate change are having a positive influence on overall carbon emissions. It seems that they are not getting worse. Is this progress?

Environmental Product Declarations & Print Media

An Environmental Product Declaration (EPD) is a quantification of something’s environmental impact. EPDs can be created for anything from home furnishings to newspapers. They provide all sorts of environmental data, from raw material impact through to emissions to water and waste generation. They are wonderful tools, but they are so very bound up with environmental science that business people tend to ignore them. Bad idea.

Not Quite Hobson’s Choice

Environmental management is something all businesses should bother with, but it’s such a wooly term. In a way it has to be vague because it means running your business to have the least negative environmental impact possible, and how do you define that? If you’re in the mining business your challenges will be rather different than if you are a florist. The graphic arts industry has equivalent extremes, from gravure printing that has to deal with very nasty chemicals, to digitally printing documents on demand, the producers of which give chemicals and their disposal barely a second thought. Environmental management in all cases is necessary and useful. Fortunately there are only two options we consider relevant for all graphic arts situations.

Taking the P**s

The idea of using rubbish to create energy goes back to the first bonfire, but only a handful of companies in the graphic arts industries seem to be paying much heed to using biomass. Toppan Printing has developed a laminated packaging material that contains around 10% of biomass and Toppan expect it to be commercially viable this year. Paarl Media, one of South Africa’s biggest publishing companies, has installed a biomass boiler at its Cape Town plant. It burns weeds and woodchips and uses the steam generated to power Paarl’s gravure presses.
