ACS Sustainable Chemistry & Engineering Virtual Special Issue—Lignin as a Renewable Substrate for Polymers: From Molecular Understanding and Isolation to Targeted Applications

Lignocellulosic biomass is a substrate with great potential as a renewable replacement for fossil-based building blocks in polymer and material synthesis. In recent years, there has been tremendous growth in the production of research papers related to these efforts. Furthermore, the strategic targets set by several nations to be bio-based economies, and motivated to some extent by the climate mitigation goals set by the UN, lend credit to the urgency of the implementation phase.

In this virtual special issue (VSI) of ACS Sustainable Chemistry & Engineering, multidisciplinary research related to lignin is reported and includes the areas of lignin biosynthesis and polymerization, lignin characterization, lignin refining/biorefining to obtain building blocks for polymers, and polymer and material systems based on lignin. Highlights of the research papers are presented below.
