<p>The present invention includes a method of landfill (3, 4) mining which comprises the following steps: converting the landfill (3, 4) to aerobic production by injection (7) of moisture and air, and a raw material such as sewage sludge, and venting (1, 2) of depleted air and moisture, thereby increasing the rate of waste decomposition; excavating the landfill (3, 4) to remove material; separating the removed material to substantially isolate at least one segregated material from the residual material; disposing of at least one segregated material; and returning the residual material to the landfill (3, 4). The segregated materials preferably include decomposed waste. The rate of aerobic production may be controlled as follows: if the temperature in the landfill becomes too high, then additional air and water may be injected (7) to cool the landfill (3, 4); and if the temperature in the landfill (3, 4) becomes too low, then additional raw material such as sewage sludge may be injected to increase the reaction rate.</p> |
