Lignin Source and Structural Characterization

Sources and structures : Lignin is a primary component of lignocellulosic biomass and an underutilized industrial feedstock. Currently, about 95 % of industrial lignin is burned as fuel in heat and power plants because its structure hinders direct industrial utilization, and 5 % is used for applications after modification. Hence, the development of...

Similarities in Recalcitrant Structures of Industrial Non‐Kraft and Kraft Lignin

What difference does it make? The structures of industrially isolated non‐kraft and kraft lignin samples are thoroughly characterized and found to exhibit similarly condensed and partially depolymerized structures. The non‐kraft lignin samples are thus expected to be ill‐suited as a feedstock for lignin depolymerization. Differences do exist in these...
