ABSTRACT:
A rotary drum air separation system separates mixed solid materials into a light fraction and a heavy fraction with substantially no stagnation of material in the air drum. It further provides for processing high volume urban solid waste without first size reducing the waste. The system separates such waste into a light fraction, substantially free of glass and ready for composting or for use as a source of energy in the form of heat or combustible gas from pyrolysis, a heavy fraction, and a glass-rich fraction from the heavy fraction, all in a high volume operation.
