摘要： PROBLEM TO BE SOLVED: To improve classification accuracy and recovery accuracy by adopting two-stage crushing by utilizing the characteristics, such as low-temperature embrittleness and non-embrittleness of materials and sorting non-crushed materials in order to crush lumpy materials, such as motors, compressors and transformers of waste electrical products, etc., to sort these massive materials by materials and to recover resources. SOLUTION: The lumpy materials are taken out of the raw materials 20. These lumpy materials A30a are sorted to the small-piece materials 24 subjected to low-temperature brittle crushing under an impact effect by a first crushing machine 12 and the non-brittle lumpy materials 30B. The lumpy materials 30B are further crushed by a second crushing machine 13.

摘要： PROBLEM TO BE SOLVED: To separate a chlorofluorocarbon gas sealed in closed cells from a heat-insulating material and recover the gas as a chlorofluorocarbon liquid when the foamed heat-insulating material (e.g. a rigid foamed urethane foam) is treated for disposing it. SOLUTION: A rigid foamed urethane waste is finely crushed to the same particle diameter as the closed cell using a crusher 1, and the finely crushed waste is separated into a finely pulverized resin 12 and a foaming gas 13 by a separator 2. In addition, the foaming gas 13 is cooled at a temperature level below the vapor pressure temperature of chlorofluorocarbon by a cooling/ condensing device 4a, and the recovered chlorofluorocarbon liquid 14a is stored in a tank 5. Further, a non-condensed gas 15a is returned to the crusher 1 and a part of the non-condensed gas 15a is subjected to adsorption of a very small amount of the chlorofluorocarbon in an adsorption device 6 again to obtain a cleaned gas 16.

摘要： PROBLEM TO BE SOLVED: To improve the quality of valuables recovered from waste contg. printed wiring boards and to suppress the scattering of lead contained in the boards. SOLUTION: A board sorting means 23 for separating the disintegrated board from the pieces of which nonferrous metals and plastics are difficult to be separated by eddy-current separating or gravity separating is provided on the downstream side of a crushing means 21 to separate the waste contg. the boards. Consequently, the lead contained in the boards are recovered without being scattered, further the quantity of the substrate mixed into other wastes, especially the nonferrous metals and plastics, is reduced, and the quality of the recovered valuables is improved even if the waste contg. the boards are disintegrated by a disintegrating means.

摘要： PROBLEM TO BE SOLVED: To accurately grasp necessary data for control such as a source, the date of receipt, the executor of treatment, and the date of treatment by product, to perform the selection of proper treatment for every product, and also to improve the treatment speed in the recycle system of a waste industrial product. SOLUTION: An electronic tag (RF-ID) is fitted to a waste product to enable the reading and writing of necessary data for treatment by a reader/writer. At a point of time when and in a place where the waste product is received from a discharger, necessary basic data for treatment is written in the electronic tag 1. After that, by performing the reading or overwriting of the data, an aptitude treatment route is determined for every product. The property of plastic material is measured, and its result is written in the electronic tag 1. Classification of the decomposed parts is performed by fitting the electronic tag 1 to pallets 52-56 each, reading the data of the electronic tag 1 fitted to the waste product therein, and writing a code of the destination to classify in the tag 1 of the pallets 52-56 each based on the data.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus capable of easily separating metallic block material from wasted electrical appliances which are valuable resource material in order to improve a recovering efficiency of the valuable resource material from the wasted electrical appliances. SOLUTION: A corresponding data is read out by a device 50 for use in discriminating the type of wasted household electrical appliances flowed from an upstream side of a system so as to determine a cutting position and then a position of a stopper 3 is controlled in such a way that a space between the cutting device 2 and the stopper 3 may become a determined value. Then, the conveyor is moved until a part of the wasted household electrical appliances is abutted against the stopper 3 and one surface of the appliances becomes in parallel with the stopper 3 and the cutting device 2 is operated when they are in parallel with each other and the appliances are cut.
