Abstract:
A method of granulating compost material, comprising the steps of:providing a source of dried pulverized compost material in a size distribution of 90% of less than âˆ’150 mesh; forming a moist mixture of dried pulverized compost and binder containing moisture, said mixture containing up to 11% by weight free moisture in said mixture; mixing said mixture sufficiently to invert the hydrophobicity of said pulverized compost material, where said pulverized compost material absorbs said moisture from said binder and forms a flowable compound; granulating said mixture into granules on a pan by contact of said mixture with additional binder material and a surfactant; and forming compost granules in a size distribution of 3 mesh to 12 mesh.
