LIGNOFUN is a groundbreaking initiative founded on the transformative idea to replace fossil-derived aromatic chemicals with sustainable, lignin-based alternatives while addressing environmental challenges like greenhouse gas emissions and resource depletion. In the phase one, the project aims to advance two key lignin depolymerization technologies (METNIN and OHRIGINS) to industrially relevant scale (TRL6-7) and valorize low-value underutilized lignin from paper mills into valuable aromatic molecule rich streams. The second phase focuses on validation and TRL progression for each of these depolymerized streams into high-value demonstration prototypes (such as foams, nylon 66, adhesives, coatings, composites, wood panels, cosmetics, personal care products and rubber products), showcasing their potential for superior performance and economic viability. LIGNOFUN will also conduct a thorough impact assessment through process simulations and curated mass balance data, utilizing TEA, S-LCA, ssBD, and LCC analyses to optimize sustainability, economic feasibility, and social impact. The project’s robust consortium of 18 partners (7 SMEs, 1 large company, 9 RTOs, and 1 cluster) unites expertise from both industry and research, ensuring end-user engagement and the industrial adoption of results. By engaging stakeholders across the value chain, LIGNOFUN will foster industry uptake of sustainable, bio-based alternatives. The project will revolutionize lignin utilization and empower EU industries to reduce fossil dependence, driving sustainability, innovation, and competitiveness for a greener future.
