[0002] At present, the current situation of construction solid waste is that the amount of construction solid waste is large: with the acceleration of urbanization, a large number of old buildings have been demolished and new projects have been started continuously, resulting in an increase in the amount of construction solid waste generated year by year. Construction solid waste mainly includes concrete blocks, bricks and tiles, waste steel bars, waste wood, waste plastics, waste glass, etc., with complex composition and great difficulty in treatment.

[0003] Although construction solid waste has certain resource value, the resource utilization rate of construction solid waste in my country is relatively low at present, and a large amount of construction solid waste is still mainly landfilled and piled up. Construction solid waste is piled up in the open air, which is prone to dust, leachate and other pollution, causing serious impacts on the soil, water and atmospheric environment. The valuable metals, concrete blocks and other recyclable resources contained in construction solid waste have not been effectively utilized, resulting in resource waste.
