Abstract
Lignin is the largest store of renewable aromatic carbon on earth. Due to its recalcitrant nature, it is often burned as a low-value fuel rather than utilized for its full chemical potential. In this book chapter, we discuss a range of topics from the structure of lignin to potential applications of lignin-derived products. The structure of lignin depends on the source, and is further modified by the method with which it is extracted from the source. Both source and extraction methods have major influences on the ease, extent, and products of subsequent depolymerization. The various extraction methods, with special attention to their impact on the efficacy of lignin biorefining and base catalyzed depolymerization, are considered in depth. Finally, the production of high value products, such as flavonoids and lignin nanoparticles, is fully discussed, as well as potential applications across various industries, particularly their use as antioxidants in pharmaceuticals.
