Abstract
A method and apparatus for organic waste treatment are disclosed. The method comprises the steps of adding a sorbent to a waste product to form a fluid matrix which may then be subjected to a compressive force to dewater the matrix. Thermal desorption and pasteurisation of the matrix may then be carried out. The sorbent added is draff, which may be obtained as a by-product from various industries, including the distillation of spirits. The apparatus comprises generally a dewatering compressor, but may also include a thermal desorption unit, which may thermally dewater the matrix and pasteurise it.
