Lignin to produce fertilizer

Lignin is a complex plant-derived polymer found in the cell walls of almost all dry-land plants. It binds cellulose and hemicellulose together, giving wood its stiffness and resistance to rotting. After cellulose, it is the biggest renewable source of carbon anywhere.

What is fertilizer?

Crops need nutrients to grow. Any nutrients required by plants is obtained in the form of minerals which might be organic (e.g. manures, residues or soil organic matter) or mineral fertilizer. Recently, it has been estimated that without mineral nitrogen fertilizers 50% of the world’s population would not be fed, resulting in mass starvation and global crisis

Using lignin to make fertilizer

Sustainable fertilizer additives improve the quality and stability of fertilizers. Ranging from improving grain hardness to avoiding the loss of nutrients such as nitrogen, phosphorus, potassium and sulfur, our products prevent dust build-up and caking. In addition, LignoStar products find improved use to prevent the formation of lumps in fertilizers during the rainy season due to fluctuating storage temperatures, thus maintaining the quality of the fertilizers. By doing this, you add value across the fertilizer supply chain with solutions for manufacturing, processing, as well as blending as well as transportation operations around the world. The strong binding power of lignosulfonates, along with their ease of use and inherent biodegradability, makes them an invaluable processing aid. However, it is important to point out that modified products also serve as highly effective fertilizer additives against dust when mixing. In addition, StarLig Magnesium Lignosulfonates can act as a useful source of Mg, an element essential in the photosynthesis process as a building block for chlorophyll. It is also well known that StarLig Lignosulfonates act as urease inhibitors providing another beneficial property to the formulation of nitrogenous fertilizers.
