A method and system for marking and encoding recyclability includes material identification markers to enable a robot with computer vision capability to properly identify and distinguish between various materials. The material identification markers could include marks or symbols to describe a recyclable item or material. The material identification markers may be incorporated into the design of the item, printed on the item or label, or placed in any other way as this is a vision-based system. Further, the material identification markers may be visible or invisible to the human eye.
