Document Type and Number:
WIPO Patent Application WO/2016/204619
Kind Code:
A3
Abstract:
A method of waste separation comprises irradiating the waste by a source of radiation, capturing an image of the waste when irradiated by the source of radiation; wherein an item in the waste is provided with a pattern, the pattern being provided in or on a surface of the item, the pattern forming a repetition of dots, a code being stored in a sequence of adjacent ones of the dots, processing the image to detect the pattern; deriving the code from the sequence of adjacent ones of the dots of the pattern; separating in accordance with the code the item comprising the pattern from the waste. The pattern may be a relief pattern. The relief pattern may comprise a pattern of bumps and recesses The pattern, such as in a form of a relief, may also be applied to identify the item. The item may be a manufactured item, such as package, e.g. a bottle, as tray or a foil, or any other item. The source of radiation provides floodlight irradiation along at least part of the surface of the item. Each dot forms a bump or recess of the surface of the item, the floodlight irradiation along at least part of the surface of the item forming by the dots an image of highlights and shades on the surface of the item,The capturing the image of the waste when irradiated by the source of radiation comprises capturing the image of highlights and shades, and the code is derived from the captured image of highlights and shades.
