[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals. Construction waste is not real garbage. After sorting, removal or crushing, most of the construction waste can be reused as renewable resources, such as: waste steel bars, waste iron wires, waste wires and other metals, after sorting, concentration and re-recycling, can be processed into various specifications of steel; waste bamboo and wood can be used to make artificial wood; bricks, stones, concrete and other waste materials can be crushed to replace sand and used in masonry mortar, plastering mortar, etc., and can also be used to make paving bricks, lattice bricks and other building materials.
