The variability in nutrient composition of Anaerobic Digestate granules produced from high shear granulation

► Fertilizer granules had more nutrients compared to raw limestone though less than synthetic fertilizer. ► Potassium concentration in product was higher that average. ► Nutrient homogeneity increased with impellers speed, granulation time and liquid/solid ratio. ► Potassium nutrient was released much faster than phosphate nutrient.
