Alkaline Lignin is a type of lignin extracted from wood or plant pulp using an alkaline process, like the Kraft (sulfate) or soda pulping methods. It's a complex, organic polymer that gives plants their rigid structure.
During pulping, it's dissolved into a liquid known as black liquor. It is then precipitated and purified from this waste stream.
Its key characteristics are:
Water-soluble (especially compared to other lignin types).
Contains sulfur (if from Kraft pulping) or is sulfur-free (if from soda pulping).
Its primary value is as a renewable, bio-based raw material used as a:
Dispersant in concrete and dyes.
Binder for animal feed, dust control, or wood pellets.
Precursor for carbon materials and chemicals.
In essence, it's a versatile by-product of the paper industry valorized for its useful chemical properties.
