Sappi Biotech’s lignin activities date back almost 100 years, and today we have operations in Europe and South Africa.
The usefulness of commercial lignosulphonate products is based on their various properties:
Binding: A very effective and economical adhesive, acting as a binding agent or ‘glue’ in pellets or compressed materials
Dispersing: Prevents the clumping and settling of undissolved particles in suspensions. By attaching to the particle surface, lignosulphonate keeps the particle from being attracted to other particles and reduces the amount of water or dilution needed to use the product effectively
Emulsifying: Stabilises emulsions of liquids like oil and water which do not form a homogenous mixture when added together, making them highly resistant to separating, and
Sequestration: Ties up metal ions, preventing them from reacting with other compounds and becoming insoluble. Metal ions sequestered with lignosulphonate stay dissolved in solution, keeping them available to plants and preventing scaly deposits in water systems.
