Printweek are today reporting the results of a trial where a used paper trial recycling trial containing 5% of HP indigo paper has been recycled, albeit in a specialist paper recycling mill. And thats at just 5%, with 95% of the paper from other non HP indigo sources… The problem is that processes such as HP Indigo contaminate the paper recycling planst and produce this – recycled paper with coloured ink in it that cannt be removed using normal processes:
The industry trade body for recycling body INGEDE commented on the trial as reported by Printweek as follows:
….. However, deinking trade body Ingede questioned the value of the trial, because it was carried out at the highly specialised Greenfield site, a Bright White Office Paper mill, rather than at a standard de-inking plant.
Ingede’s Axel Fischer said: “These results are interesting, but not surprising. This is not proof that it will work in every mill, this is not a model for a general deinking plant, and it does not change our attitude of the deinkability of Indigo.
“This only means that HP should label Indigo as Indigo paper, collect it and ship it to Arjowiggins but keep it out of the rest of Europe.” …. (emphasis ours)
I think that confirms that if you want your digital labels to be recyclable and not contaminate the waste paper industry’s raw material stream so it may have to go to landfill, then you must continue to specify on Xeikon digital printing, and not HP Indigo. And of course, its brilliant quality, FDA foodsafe and very cost effective !
