Abstract:

Lignin is after cellulose the second most abundant biopolymer in the biosphere, and the main polymer based on aromatic units. 50 million tons of lignin are generated every year mainly from wood pulping in the form of sulfonated lignin, but only 2% of this production is used as filler in plastics, as dispersants or for the synthesis of vanillin and DMSO; the remaining is used as energy source. The main limitation to its use as chemical building block is the high content of sulphur moieties, associated with the traditional extraction processes, which impede its reactivity. However, with the emergence sulphur free-lignin classes, there is a renewed interest in exploring the potential of this natural abundant biopolymer, through its conversion by various chemical pathways, toward the production of chemical, additives, fillers, different classes of polymeric materials for a wide range of applications. This keynote presentation will provide an overview of recent advances in converting lignin into functional polymeric materials for more sophisticated applications. An emphasis will be giving to new trends on using sustainable green chemistries in order to produce these new functional polymeric materials, which will open new horizons for this unexploited renewable feedstock.
