ABSTRACT:
A process for the preparation of a high grade fertilizer from pressing residues obtained from wine and fruit juice production is disclosed wherein the residues are first stored under anaerobic conditions and are then loosely mixed with air to produce a mass which then undergoes intense aerobic degradation to produce heat, carbon dioxide, moisture and a finely divided high quality fertilizer. Apparatuses for carrying out this process are also disclosed.
