Leather tanning

The phenolic structure of lignin yields benefits in tanning and leather applications.

Excellent water solubility and dispersing properties as well as suitable molecular mass distribution and low viscosity of aqueous solutions of lignin support fast, nearly complete penetration of hides, with physio-chemical reaction progressing over time.

Lignin is a major component of wood and is one of the most abundant natural organic wood polymers which provides a multitude of functionalities.

Our lignin is used in a variety of industrial and agricultural areas for various applications.
