A pioneering academia-industry collaboration has created an improved bio-based printing ink made from coffee-roasting waste, providing a renewable alternative to synthetic pigments commonly used in fiber-based technology,

The water-based ink was developed collaboratively by Natural Indigo Finland, Tampare University of Applied Sciences (TAMK) and Siegwerk and uses a bio-colorant from coffee waste supplied by Meira, with formulation support from Adra Pakkaus. It contains no VOCs and uses Siegwerk’s high bio-renewable content (BFC) technical varnish as a binder.
