  "textContent": "In the COCOBIN project, coordinated by the University of Oulu, coating materials are being developed from suberin, a natural compound found, for example, in birch bark. In plants, suberin acts as a protective layer and prevents the loss of water. Up to 1,500 meters of a bio-based coating material prototype have been produced at semi-pilot scale.",
