Abstract
A sorting member with an optimized surface shape is adopted to pressurize a mixture heated on the sorting member to allow a melted resin mixed in the mixture to adhere to the sorting member to sort the resin from an unmelted resin. Thus, resin materials are sorted and recovered from unwanted home electric appliances and the like at a high purity.
