Abstract

A method for digesting organic waste comprises the steps of providing a source of organic material undergoing anaerobic bacterial digestion in a liquid phase within a liquids digestion vessel 5, providing organic waste material containing biodegradable solids to a solids digestion vessel 3, feeding at least a part of the liquid phase from the liquids digestion vessel 3 to the solids digestion vessel 5, after a predetermined time, separating solids materials above a specified size from other materials in the solids digestion vessel to produce a high-nutrient plant-growth material 7, feeding at least some liquid from the solids digestion vessel 3 to the liquids digestion vessel 5 and optionally further dewatering at least some of the separated solids materials 7 to produce a fibrous low-nutrient material 12 suitable for use as a solid fuel and/or a building material, and feeding at least some of the liquid 11 from the dewatering process to at least one of the digestion vessels, preferably the liquids digestion vessel 5. In a preferred embodiment, heavy material such as grit is removed from each of the process stages.
