ANR ReCoLV project (2025 – 2029)

The composite materials market is booming, relying on the excellent performance of epoxy resin composites. However, this aromatic thermoset, in addition to being of fossil origin, has the disadvantage of not being recyclable. Lignin is the most abundant aromatic biopolymer available on Earth. In this sense, it represents an excellent bio-based alternative to the industrially used epoxy resins. The incorporation of lignin into materials remains very limited due to its complexity and unsuitable physico-chemical properties. The ReCoLV project aims to develop new 100% bio-based matrices containing high levels of lignin through clean, efficient, and affordable chemical modifications of lignins with bio-based reagents. The crosslinking of this matrix will be ensured by a vitrimers network of dynamic covalent bonds to obtain recyclable and repairable composite materials.
