In Tree2Ink, we aim at producing a fully renewable multipurpose biobased black ink which will be validated in relevant environments, including printing and dyeing technologies. Wood-based carbon and cellulose pulp are converted using a one-pot ball milling process into a nanostructured colloidal ink composed of carbon particles as pigments and cellulose nanofibers as transparent binders. We plan on achieving TRL5 by decomplicating the production process, assessing the sustainability and feasibility of the process to find bottlenecks that can be technically addressed, scaling up the production of bioinks from hundreds of milliliters to liter scales, and testing it in real-life applications using the relevant infrastructure.
