<p>Sorting dissimilar materials, such as sorting plastics from wood, foam, or rubber. These systems and methods employ either dielectric heating or fluorescent dye absorption characteristics of materials to distinguish the materials. The systems and methods may employ differential dielectric heating and thermal imaging to sort wood, rubber, and foam, from plastic, metals, and other materials that do not undergo dielectric heating. Similarly, systems and methods may employ the greater liquid absorption properties of wood, rubber, and foam as compared to plastic. The dissimilar materials are subjected to fluorescent dye and carrier liquid, that is differentially absorbed by objects. Fluorescent imaging can be used to distinguish the materials. In either case, a computer-controlled system can be used to sort material types based on an evaluation of the thermal or fluorescent image.</p> |
