    Abstract: A method for reducing the content of a heavy metal in a mixture of solid plastic materials, wherein the mixture includes plastic flakes and there are at least two different colors of plastic flakes in the mixture. A percentage of each of two or more colors of flakes in the mixture is determined. A heavy metal content in the mixture based on the determined percentages is predicted. Whether the predicted content of the heavy metal in the mixture exceeds a pre-determined threshold is determined. If the predicted content exceeds the pre-determined threshold, a color sorting step is performed to obtain a subset of the mixture of plastic flakes, wherein the subset of the mixture of plastic flakes has a lower heavy metal content than the mixture prior to the color sorting step.

  • Patent number: 8267336
    Abstract: In a method and a system for sorting shredder residues of metal-containing wastes, in particular from vehicle body shells, shredder residues are separated into a shredder light fraction and a non-ferromagnetic fraction. The method and system provide for a raw-granulate fraction being produced during the sorting of the shredder light fraction and the shredder heavy fraction in preliminary processes and a main process, by separating out at least one ferromagnetic fraction, a nonferrous-metal fraction, a fiber fraction, and a sand fraction, and the raw-granulate fraction being split up in a refining process.

  • Patent number: 8226019
    Abstract: Systems and methods for increasing recyclable material recovery from automobile shredder residue. Embodiments include substantially isotropic quantization separation of automobile shredder residue such as a wind tunnel system and even substantially horizontal laminar air flow and can be used with or without out other traditional automobile shredder residue sorting systems perhaps creating additional recyclable quantities and even better separated results such as with zorba and zurik and the like.

  • Patent number: 8210456
    Abstract: In a method of recycling sealed batteries, the batteries are shredded to form a shredded feedstock. The shredded feedstock is heated above ambient temperature and rolled to form a dried material. The dried material is screen separated into a coarse fraction and a powder fraction and the powder fraction is output. A system for recycling sealed cell batteries comprises an oven with a first conveyor extending into the oven. A rotatable tunnel extends within the oven from an output of the first conveyor. The tunnel has a spiral vane depending from its inner surface which extends along a length of the tunnel. A second conveyor is positioned below an output of the rotatable tunnel.

  • Patent number: 7955410
    Abstract: A method of removing iron from waste slag from a steel producing furnace that reduces the size of the waste slag to slag particles in a reduction zone. The slag particles are advanced along a conveyor in a first direction. A first and second magnet are positioned adjacent the conveyor to remove slag particles that have a sufficient iron content to be attached by the first and second magnets. A first removal belt is advanced between the first magnet and the conveyor to remove slag particles removed from the conveyor by the first magnet. A second removal belt is advanced between the second magnet and the conveyor to remove slag particles removed from the conveyor by the second magnet. A first and second separation screens are positioned along the conveyor to remove particles not removed by the first or second magnets that are small enough to pass through the first and second separation screens.
