Abstract
A method is provided for sorting white paper from a stream of paper wherein the concentration of white paper is less than the concentration of non-white paper. The method includes identifying the white paper by detecting the presence of an optical characteristic of the white paper as the stream of paper is passed by a sensor. Then the white paper is ejected from the stream of paper by controlling one or more actuators directed against the white paper, and thereby separating the white paper from the non-white paper. The method is particularly applicable to the sorting of white paper during curbside recycling.
