on:<\/strong><\/span><\/h4><ul><li>Scaling up selected coating formulations<\/li><li>Testing compatibility with existing industrial coating lines<\/li><li>Further validation in real-world food packaging applications<\/li><li>Ongoing life cycle and socio-economic assessments<\/li><\/ul><p>In parallel, the project continues to address key challenges, including cost optimisation, biodegradability, and regulatory compliance, to ensure market readiness. Selected best performing coating formulations as developed by Wood K plus and applied by spray onto paper as substrate material achieved the following Key functionalities:<\/p><ul><li>Excellent grease resistance was achieved (KIT rating up to 12 \u2013 maximum level)<\/li><li>Strong water repellence with Cobb values up to ~3.5 g\/m\u00b2<\/li><li>Successful thermoforming trials for coated paper trays<\/li><li>Up to 98% bio-based content in selected formulations<\/li><\/ul><p>These results confirm the feasibility of high-performance, PFAS-free coatings that are compatible with industrial processes (converting thermoforming step) and meet recyclability and safety requirements. In close cooperation with an Italian End User Ecozema the selected coated papers were successfully thermoformed using industrial machines and the paper-based food trays are shown in the Figures. As it can be seen from the above shown pictures dependent on the lignin chemistries and manufacturing process as well as lignin loading different colour of the coatings could be achieved. As next step recycling process of selected food trays is ongoing following CEPI standard in close collaboration with member of BIO-SUSHY Advisory Board.<\/p><p>To support BIO-SUSHY Dissemination and Communication activities Wood K plus participated actively in several Online Events: Sustainable Materials for Coatings held on April 14<sup>th<\/sup>, 2026, organised by European Bioplastics (EUBP) <a href=\"https:\/\/zenodo.org\/records\/19571665\" rel=\"noopener\">https:\/\/zenodo.org\/records\/19571665<\/a>, where Ivana Burzic gave a talk on \u201cDry powder lignin-based coatings for electrostatic spray applications \u2013 paper-based food trays\u201d.
