Indexing and sorting robot based on hyperspectral and reflectance information for CDW recycling

This paper presents preliminary results from the development of a novel CDW robotic sorting system. Data from hyperspectral cameras and reflectance sensors will be combined to produce a 2D heat map for object classification by an algorithm which is under development. A 6 Degrees of Freedom robotic arm will be utilised in handling and sorting the CDW particles. The final goal is to achieve purity higher than 90% for each fraction. Different material classes will be sorted and recycled in prefabricated construction applications. Preliminary results indicate that coupling the hyperspectral information and the robotic technology allow to achieve high-quality sorting of CDW.
