Welcome!

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.

Deinking glass

It takes a million years for glass to biodegrade, so it’s good that we’ve worked out sensible recycling processes for it. However as the packaging industry gets slicker, we need to look more carefully at how we can keep recycling glass, particularly containers, effectively. Digital printing technology is making it easier to print direct to shape (DtS) and as we turn away from plastics, we need to be thinking more about ink formulations and deinking processes for glass containers. It must be economically viable to continue recycling them without increasing environmental impacts through more complex deinking and recycling processes.

ISO 21632 for calculating the energy usage of digital printing devices

It’s got a long and clumsy title, but what ISO 21632 (Graphic technology — Determination of the energy consumption of digital printing devices including transitional and related modes) can do for the graphics industry has nothing to do with clumsiness. Far from it. This document will help make short run digital printing devices, including large format machines, much more environmentally accountable.

Invest in the right printing plate

It’s amazing how long it took for computer-to-plate (CtP) technology to become widespread. CtP in prepress has made a huge contribution to improving print’s environmental impact. Going direct to plate and bypassing the film imaging and contacting stages removes processes in printing plate production. CtP had been around since the 1980s, but its key goals proved elusive. That all changed in 1995.

Sustainability messaging part 4

We’ve not forgotten about our effort to provide a ten point plan for companies and associations who want to be proactive with their sustainability messaging. In the previous blogs we have suggested improving waste management throughout the supply chain. This is a key contributor to reducing environmental impact, especially for printing companies dealing with preconsumer waste.

After so many years of environmental dithering, things are starting to move and change is coming. Unilever, one of the world’s largest corporations has signed an important deal with Veolia. This company provides services to local governments specifically in water, waste, transport and energy management. Unilever, a huge print and packaging buyer, is working with Veolia to improve local recycling infrastructures, specifically for plastics recycling and recovery.
