  • Reducing the content of heavy metals in recovered plastics
    Patent number: 8302777
    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.
