The main aim of this research was to investigate the feasibility of producing an organic fertiliser using waste materials and limestone powder as the raw materials using the process of high shear granulation. The waste materials are anaerobic digest tea waste and sodium-based lignosulfonate. Successful production of improved soil conditioner would reduce the amount of synthetic fertiliser for farm application. It would also provide a sustainable way of managing waste. Two factorial experimental design was used to determine the effect of process and formulation variables on the strength, size distribution, resistance to attrition yield of the granules and nutrient homogeneity of the granules. Additional understanding of the granulation process in the high shear mixer involving binary powder mixes with different physical characteristics was provided.
