Patent number: 8985339Abstract: In a method and an arrangement for treating a light fraction that is produced during the treatment of plastic-rich waste that is low in metal, at least the following steps are carried out consecutively: the light fraction is stressed by percussion and/or bashing, the light fraction is classified into at least two light fraction classes, at least one light fraction class is separated into at least one light material fraction and a heavy material fraction, at least one light material fraction is cleaned. The cleaning of the light material fraction (fibrous material), obtained after the separation, provides a very clean initial substance to be obtained, resulting in clearly improved material recycling and energy recovery.Type: GrantFiled: March 21, 2009Date of Patent: March 24, 2015Assignees: Volkswagen AG, Sicon GmbHInventors: Heiner Guschall, Daniel Goldmann

Patent number: 8623929Abstract: In a method and equipment for conditioning low-metal scrap high in plastics, which contains at least partially scrap high in plastics from shredder processes, especially of scrap vehicles, the method includes: splitting up ferromagnetic components from the scrap that is high in plastics; separating a first raw sand fraction from the scrap high in plastics that has been reduced in metals; reducing in size the fraction high in plastics that remains after the isolation of the first raw sand fraction; separating a second raw sand fraction after reducing in size the remaining fraction high in plastics; and splitting up the remaining fraction, that is high in plastics, into a light fraction and a heavy fraction. The equipment has the appropriate device for carrying out the individual method steps.Type: GrantFiled: March 18, 2008Date of Patent: January 7, 2014Assignees: Volkswagen AG, Sicon GmbHInventors: Bram den Dunnen, Michael Knust, Heiner Guschall

Patent number: 8556201Abstract: In a method and equipment for conditioning a heavy fraction high in plastics, which is obtained by conditioning low-metal scrap high in plastics, which originate at least in part from shredder processes of scrap vehicles, the method includes: isolating metal parts from the heavy fraction high in plastics; reducing the size of the metal-reduced heavy fraction high in plastics that remains after the isolation of the metal parts; splitting up of the metal-reduced heavy fraction high in plastics, that remains after the isolation of the metal parts, into fractions high in plastics having different grain sizes; conditioning the separated fractions high in plastics at least partially in separate processes. The equipment includes appropriate devices for carrying out the foregoing processes. A highly pure granulate fraction may be obtained, which may be fed to material utilization.Type: GrantFiled: March 23, 2012Date of Patent: October 15, 2013Assignees: Volkswagen AG, Sicon GmbHInventors: Michael Knust, Bram den Dunnen, Heiner Guschall, Daniel Goldman

Patent number: 5908165Abstract: A process and apparatus for reprocessing mixed plastics, more particularly mixed plastics from household refuse. The material being reprocessed is shredded in a shredding stage, agglomerated in an agglomerator wherein volatile substances are sucked off by suction devices, and the agglomerated material is dried over a drying path. In order to reduce obstructive substances, such as paper and ash, the fine grain portion in particular of the plastics agglomerated is screened off. With the drying process it is possible to produce without wet processing steps which are high in energy consumption a plastics agglomerate of high quality which is suitable for industrial re-use.Type: GrantFiled: July 2, 1997Date of Patent: June 1, 1999Assignee: Der Gruene Punkt-Duales System Deutschland AktiengesellschaftInventors: Dietmar Guschall, Heiner Guschall, Axel Helmerth, Jorg Himmel, Gerhard Fahrbach, Heinz-Reiner Schnettler
