Lignin, alkali is widely used in industrial applications due to its natural polymeric structure and binding properties. It serves as a dispersant in agrochemical formulations, helping to evenly distribute active ingredients in pesticides and herbicides. It is also used in concrete admixtures to improve workability and reduce water content without compromising strength.

In the dye and pigment industry, it acts as a stabilizer and dispersing agent, preventing particle aggregation. Lignin, alkali finds use in drilling muds for oil well operations, where it helps control fluid loss and stabilizes the borehole.

It is employed in animal feed pellets as a binder to improve pellet hardness and reduce dust. Additionally, it is explored in sustainable materials as a renewable component in bioplastics, resins, and as a precursor for bio-based antioxidants. Its ability to chelate metals also makes it useful in water treatment and soil conditioning applications.
