<p>In order to provide a method and apparatus for processing solid organic waste to produce a fuel or organic compost, the waste material is treated in a rotary anaerobic digester (116), where it is digested in the thermophyllic phase at a temperature in the range 60 - 75 °C, to produce a treated material having a moisture level not exceeding 45 % by weight and preferably not exceeding 35 % by weight. The treated material can be subsequently dried on a drying floor (123) to provide a stable product. Waste having a high moisture level, such as domestic waste can be blended in a blender (115) with waste having a lower moisture level, such as commercial waste, to provide control of the properties of the waste being treated and of the product obtained. The treated solid organic waste from the anaerobic digester may also be pyrolised and, optionally, subsequently gasified.</p> |
