Construction waste is not real garbage, but "gold" that has been misplaced. After sorting, removing, or crushing, most construction waste can be reused as renewable resources. For example, scrap steel bars, scrap iron wires, scrap electrical wires and other metals can be sorted, concentrated, and reheated to be processed and manufactured into various specifications of steel; Waste bamboo and wood can be used to manufacture artificial wood, which makes the recycling of construction waste highly efficient, cost-effective, widely applicable, and environmentally and economically beneficial.
