PROCESS FOR THE INTEGRATED AUTOMATED COMPOSTING OF GREEN AND DOMESTIC WASTES FOR PRODUCING NATURAL FERTILIZERS

摘要

The invention relates to a process for the integrated automated composting of green and domestic wastes in order to produce natural fertilizers by processing the chopped organic residues with sizes of 0.5...1 cm and whose C/N ratio is from 20/1...40/1 whereto there are added biocomposting stimulators, pH regulating agents, 1...10 % biopreparations, 0.1...5% biodynamic preparations, afterwards the mixture is processed in three stages for a total period of 33...62 days in an automated system, at a temperature of 50...65°C, 65% humidity, which finally reaches 40%, final pH between 8.5 and 5.5, to obtain a compost comprising 73...91% organic matter, 1...3% total nitrogen, 0.2...1% potassium and 0.2...0.5 % phosphorus.
