Functionalized lignin degradation molecules as platform chemicals for the production of adhesives, paints, polyurethanes and epoxides
In the Lignoplast joint project, 5 research institutes and 8 industrial companies develop innovative processes for the production of aromatic building blocks from various lignin types and their application in adhesive, paint, polyurethane, and epoxy systems. Different technical lignins from pulp production, such as Kraft lignin, and lignins from "biorefinery" processes are used as raw materials. Lignins from "biorefinery" processes are produced as residues of the enzymatic or acidic saccharification, such as Organosolv lignin or hydrolysis lignins.
The required aromatic compounds are obtained by means of hydrolytic degradation of the macromolecular lignins and subsequently functionalized chemically and enzymatically. The structure of the synthesis building blocks is adapted in such a way that new adhesive, paint, polyurethane, and epoxy systems can be formulated. These are used in sample materials and components, which are characterized by application technology and compared with conventional systems. Throughout the entire process chain, economic and ecological balancing and, finally, concept development for industrial implementation take place.
The lignin-based products are used in trial materials and subsequently characterized in terms of their application technology and compared with conventional systems.
