Abstract:
This relates to the treatment and purification of refuse by composting in the form of thermal retting. Conventional refuse is treated by the addition of moisture, preferably in the form of sludge, after which it is crushed in a mill and is screened in tube screens with large particles being removed and discarded, intermediate particles being returned to the crushing mill, and small particles being delivered for composting. Metals, particularly ferrous metals, are removed from each of the three classes of screened material and are salvaged.
