2025 AIChE Annual Meeting

Session: Advances in Lignin Chemistry, Isolation, and Depolymerization

Lignin valorization is a crucial theme in current biomass utilization strategies. It shows great potential as a feedstock for producing alternative fuels and chemicals. This session will discuss the recent technologies and fundamental understanding of lignin separation, transformation, degradation, and others.
