To further the proper and high-quality disposal of construction wastes (construction byproducts) and to improve safety in sorting operations, we have developed a system, which uses robot vision to determine materials based on the Bayes’ theorem, to sort construction byproducts of a wide variety of sizes and shapes that are discharged from building demolition sites. We have conducted, using construction byproducts discharged from actual demolition sites, sorting experiments with the developed sorting system. These experiments have demonstrated sorting accuracies of not less than 60%. These results prove the system’s effectiveness in sorting construction byproducts.
