Transforming Contaminated
Wood into Valuable Resources

WoodVALOR is revolutionising
waste wood valorization, creating
high-performance paints, coatings
and biochar for a more sustainable future.

Project Overview

WoodVALOR will epitomize circular economy principles in action. By transforming contaminated wood into high-performance paints, coatings, and biochar, we will not only divert waste from landfills but also create products that contribute to environmental restoration. The advanced decontamination and fractionation processes to be developed in the project will ensure that every part of the wood is utilized, maximizing resource efficiency.

The project’s innovative approach will leverage cutting-edge technologies to produce acrylic acid, fatty acids, and bio-based binders from the wood’s cellulose and hemicellulose fractions. By grafting these components onto the hemicellulose, we will enhance the coatings’ water resistance and durability, creating a closed-loop system where contaminated wood is transformed into protective materials for other wood products.
