LIGNICOAT project proposes the development of eco-innovative materials from lignocellulosic biomass in order to obtain bio-based sustainable coatings considering the availability and carbon footprint of resources. The project aims to increase the bio-based content of the coatings while ensuring performance and providing anti-corrosive, fireproof, and antimicrobial features. The validation of the lignin-based sustainable coatings will be performed in an industrial environment under the collaboration of relevant private companies.

Lignin is an underutilized product with a high potential to provide not only economic returns, but also environmental benefits if value-added applications are found. Although lignin is a topic of great interest, the conversion of lignocellulosic biomass into real products is not trivial and still no commercial options are available. LIGNICOAT proposal provides new synthetic routes to obtain bio-resins “à la carte” (PUD, ALKYD and EPOXY) based on lignin intermediates (Polyols, Epoxies, phosphorylated, polyacids and carbonates) for application in coatings and validated in an industrial relevant environment (TRL5).

LIGNICOAT’s ambitious goal is to assist in the transition of the Paints and Coatings industry from fossil-based to bio-based products. Depending on the intermediates and the resins used, the estimated bio-content of the coatings will vary between 60-90%. Under this scope, the project outputs will be disseminated to stakeholders and policymakers. Finally, life cycle analysis, life cycle cost and social life cycle assessment will demonstrate the sustainability and feasibility of the suggested solutions.
