  • Polystyrene recycling process
    Patent number: 5197678
    Abstract: 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.
