<p>Waste material containing humid organic matter is shredded and extruded in a perforated, cylindrical die (14). The extruded material is fermented in a silo (20) having stacked compartments provided with regulated air circulation. The material progressively drops through the silo and is sorted (76) to obtain a stabilized granulate suitable as a soil amendment. The dry residue of the extrusion is disgregated and subdivided by an airflow separator (84) into at least two fractions of material of different weights. <IMAGE></p> |
