Lignin, the second most abundant natural polymer after cellulose, plays a key role in sustainable material applications. Despite being a major byproduct of the pulp and paper industry, lignin remains underutilized, primarily burned for energy. However, advances in lignin isolation and valorization are unlocking its potential in high-value applications. This abstract provides an overview of lignin’s potential, focusing on isolation methods, market trends, and industrial applications, based on previous research findings.
