Researchers Produce Ultrapure Lignin for Biobased Materials

Lignin is one of the main components of woody plant parts. Embedded in the plant cell wall, the complex organic matter gives the wood its compressive and breaking strength. So far, lignin is mainly available as by-product in paper and pulp production and contaminated with sulfur. Researchers at the Technical University of Hamburg-Harburg now succeeded in recovering ultrapure lignin from residual wood.
