Who we are

We work with lignin chemistry: sulfite lignosulfonates, their micronutrient complexes, and humic materials from lignite and lignin. Our customers make NPK and organic-mineral granules, water-soluble fertilizers, micronutrient products and soil conditioners.

We start from the customer’s process. You tell us what you make, the product form and the target market, and we recommend a grade, send the documents and arrange a sample for your own trial.

Production and quality control

Lignosulfonate is concentrated in evaporators and spray-dried to powder. Each batch is checked for the parameters on its TDS, such as appearance, moisture, pH, solubility and active content, and every lot ships with a COA. Retained samples and order records support traceability.
