Completely new systems will be formulated using green materials, aiming to replace traditional consolidants, coatings, and packaging materials that are still established in the conservation practice regardless their environmental impact or safety risks. Vegetal proteins and polysaccharides, from renewable resources or cellulose/crustacean waste, will be used to prepare coatings and barriers to protect works of art from degradation, with by-design self-healing and reversibility characters, or consolidants to strengthen degraded/fragile artefacts (remedial conservation);
