Automatic sorting of recycled aggregate using image processing and object detection

With the growth of population and expansion of cities, the use of recycled construction materials has attracted builder's attention. Governments also initiate the utilization of environmental practices through legislation, regulations, and development controls. Despite all the efforts so far, the use of recycled aggregate is still not as popular as it should mainly due to a few mechanical deficiencies encountered. In this study, the consistency of the particles had gone subject to investigation, i.e. sorting various components found in recycled aggregate including brick, ceramic, natural aggregate, glass, plastic, etc. An image processing apparatus in companion with computer codes capable of object detection had been assembled and tested. Future studies can lead to the development of fully integrated robotic module for sorting recycled aggregate using robotic arms.
