New concepts for converting lignins into valuable products are at the core of todays most important scientific advances in biorefineries. Despite the fresh momentum in lignin valorisation, extensive efforts are still needed to unravel its structural complexity and rationalise the relationship between the structure of lignin and their physicalchemical properties to unlock lignins potential in industrial applications. This Faraday Discussion focuses on the latest developments in lignin valorisation and aims to further the understanding of the physicalchemical processes that are the basis for lignin extraction, stabilisation and degradation by bringing together researchers at the forefront of physicalchemical research. In this volume, the topics covered are organised into the following themes Native lignin solvation and extraction Lignin stabilisation and degradation in lignocellulosic fractionation processes Commercially available technical lignins Strategies for compatibilisation of extracted lignin properties with commercial applications | Royal Society of Chemistry Frontiers in Physical Chemistry for Lignin Valorisation : Faraday
