<p>The invention comprises a method and apparatus for recycling foamed polystyrene from municipal solid waste and more particularly from fast food restaurant waste. A steady stream of waste is delivered to a flail mill for reducing particle size, a rotary trommel for eliminating undersized waste and a rotary air classifier for removing ''heavy'' waste from the stream. At this point, the waste stream comprises mostly paper and foamed polystyrene. The paper and foamed polystyrene are delivered to a water pulper which fiberizes the paper so that it can then be separated from the foamed polystyrene by passing it through a screen of selected mesh size to allow the water and paper pulp to pass through while retaining the foamed polystyrene.</p> |
