Valorisation et éco-conception des déchets de bois post-consommation en produits biosourcés durables
WoodVALOR adopts a circular approach by using contaminated wood as a sustainable feedstock to produce paints, coatings, and biochar, showcasing innovative waste valorization. The process converts low-value material into high-performance products while contributing to environmental restoration. The project compares advanced decontamination and fractionation methods with traditional pulping processes. Acrylic acid is produced from the wood's cellulose fraction through the lactic acid route, while fatty acids are obtained via yeast fermentation, ensuring resource efficiency and aligning with circular economy principles. The hemicellulose fraction is transformed into bio-based binders for coatings, reducing reliance on petroleum-derived alternatives. These binders are made more hydrophobic and durable by grafting acrylic acid and fatty acids onto the hemicellulose, enhancing water resistance and longevity. Lignin, often considered a byproduct, is repurposed to produce phenolics, which are grafted onto hemicellulose to further improve the coatings' properties. These coatings are then applied to wood surfaces, creating a closed-loop system where contaminated wood becomes protective material for other wood products. Biochar, produced from process residues, serves two functions. It is used for bioremediation of contaminated soils and in mineral recovery from contaminated wood. The recovered minerals can be reintegrated into coatings, closing another resource loop. By converting contaminated wood into materials that protect wood surfaces and treat soils, WoodVALOR highlights circularity. This approach minimizes waste, promotes resource recovery, and supports environmental health and material efficiency, contributing to a more sustainable EU industry and addressing the major challenges associated with contaminated wood waste.
