More Information
Summary:The invention relates to a method for processing lignin. The method includes feeding lignin material to the system, decreasing particle size of the lignin material in a grinding device in order to manufacture lignin powder having particle size distribution wherein at least 85 wt. % of the lignin agglomerates and particles are less than 300 microns, and increasing dry solids content of the lignin material at least 5 percentage units while decreasing the particle size in the grinding device. In addition, the invention relates to a system for processing lignin, a lignin powder, a method for manufacturing a product including lignin, a system for manufacturing a product including lignin and a product including lignin powder.
