<p>There is disclosed a method for processing waste materials which include biodegradable matter comprising the steps of: a) providing a plurality of storage cells for the waste materials; b) continually and sequentially filling each cell in turn under a cover; c) sealing each filled cell; d) collecting biogas from each cell as the biodegradable material therein decomposes; and e) emptying the earliest filled cell when N cells have been filled thereafter; the number of cells being sufficient having regard to the rate at which the waste materials are received that the residence time of the materials in any one cell is such that the material is completely or substantially decomposed when the cell is emptied.</p> |
