The construction waste sorting and processing production line integrates intelligent sorting, multi-stage crushing, screening, material transportation, multi-stage dust removal and cleaning, and central program control. It crushes, screens, and winnows the construction waste. After processing, the aggregates, slag, scrap metals, and light materials in the construction waste can be accurately classified, and the aggregates can be divided into different specifications according to specific needs. After the construction waste passes through this production line, it can produce high-quality recycled fine powder, recycled aggregates, recycled fuels, recycled metals and other recycled materials.

Stale garbage is also a resource. If the existing stale domestic garbage is processed on the spot and turned into treasure, it can be "recovering lost land and returning farmland to the people" can not only produce huge social benefits, but also increase new wealth. It is estimated that if the old garbage is made into building materials, it can make up for the shortage of cement resources and be used for filling pits, paving roads, roadbeds, etc. According to the calculation that each ton of garbage building materials can replace 1.5 tons of related building materials, 210 million tons of building materials can be saved every year; if each ton of building materials consumes 2 square meters of land, 420 million square meters of land can be protected every year. Therefore, the research on the "reduction, reuse, and resource utilization" of stale domestic garbage sites; turning waste into treasure, the economic and social benefits are immeasurable.
