Sustainable Conversion of Lignin to Value-Added Products and Green Chemicals (#319)

Lignin is the second most abundant natural polymer and the largest renewable source of aromatics on earth. Developing specialty and commodity products from lignin has been a major industrial and scientific endeavor since the early 20th century, driven primarily by papermaking industry. However, after over a century of significant R&D effort, “you can make anything out of lignin … except money” still remains a myth. The emerging lignocellulose biorefinery industry will produce an enormous amount of lignin. This creates an urgent need to develop new technologies for transforming lignin to valuable products. At the same time, it is increasingly recognized that the economic feasibility is the major bottleneck hindering the commercial implementation of a large scale lignocellulosic biomass-to-biofuel conversion process. Identifying value added co-products from lignin along with the production of biofuel also provides a key solution to overcoming this economic barrier. This symposium provides a forum to discuss and demonstrate the latest developments in chemical and biological transformation of both industrial and biorefinery lignin to renewable chemicals, materials and fuel . The specific topics of this symposium include: 1. chemical transformation of lignin; 2. biological transformation of lignin; 3. new products from biomass lignin; 4. catalysts and biocatalysts for selective lignin transformation; 5. perspective toward designing new catalytic systems for lignin valorization.
