According to the Digital Print De-inking Alliance (DPDA), a study conducted in France revealed that nearly all of the samples were de-inked in test conditions.

Matthias Fromm, R&D manager for Océ Printing Systems, said the tests had been carried out using conditions that simulated the total paper recycling process for mixed grades of paper in a bid to understand the impact of inkjet printed papers in commercial recycling systems.

He added: "This research was conducted using 100% inkjet paper. We estimate that production inkjet’s market share of total graphic printing is less than 1% today.

"Based on the projected growth rates of inkjet printing, we anticipate the de-inking industry is capable at current volumes and that we have a few more years to jointly develop the appropriate technologies of paper, ink and de-inking methods to ensure good de-inking performance if and when the need arises."
