<p>A method for recovering combustible gas, soil and a fuel fraction from waste material that contains organic carbon, by forced anaerobic decomposition of shredded organic waste. The invention is further characterized in that the shredded waste is placed on a liquid-impervious support structure (2) provided with at least one drainage channel (4), such as to form a bed (3). The waste material bed is covered with heat-insulating and gas-and-liquid impervious layers (5, 6). Gas-collecting nozzles (10), inserted into the waste-material bed, are connected to flexible hoses (9), which in turn are connected to a centrally arranged gas-collecting pipe (8). Also inserted in the bed are watering nozzles (13), through which leaching water is recycled to the bed. When decomposition of the waste-material has terminated, the gas-collecting pipe and watering pipe with associated hoses and nozzles are removed from the bed and reused on a further bed of waste-material. The waste-material is then divided into a soil fraction and a fuel fraction.</p> |
