(54) Title: AN ORGANIC WASTE TREATMENT SYSTEM Figure 1 (57) : There is provided a system and method for treating organic waste comprising: an inlet for receiving organic waste; a crusher coupled to the inlet for reducing the size of the organic waste; a pre-treatment chamber for increasing the temperature of the organic waste; and a carbonization chamber for treating the organic waste via carbonization or torrefaction to form biochar. The system further comprising a metal separator, a waste liquid collection and filtering unit and a flue gas treatment system. The system is configured to recover the heat generated from one part of the system to heat other parts of the system where the heat may be required. Also provided is a method of treating organic waste comprising: providing organic waste to a crusher through an inlet; crushing the organic waste to reduce size of the organic waste; heating the organic waste to increase temperature of the organic waste; and torrefying the organic waste to form biochar.
