Construction waste is a common solid waste in cities, and the traditional way of disposal is to transport it to landfills or naturally pile it up. This practice not only occupies a large amount of land, but also damages the living environment. With the construction of "waste free cities" during the 14th Five Year Plan period, the resource utilization of construction waste is an inevitable requirement for sustainable urban development. Moreover, Xi'an city mentioned that by 2025, the utilization rate of construction waste resources in the province should reach over 60%, and the existing construction waste landfills should be gradually closed. It can be seen that the solid waste utilization industry characterized by resource recycling has ushered in huge development opportunities and market space.

The project focuses on the resource utilization of construction waste, adopting a fixed disposal method. Through a combination of "multi-stage crushing, multi-stage screening, and multiple sorting", the construction waste is developed step by step, producing different specifications of recycled aggregates such as 0-3mm, 3-6mm, 6-9mm, 9-20mm, 20-31.5mm, etc. The aggregates below 9mm are used for brick making, and the 9-20mm and 20-31.5mm suppliers are mixed, greatly expanding the channels for the resource utilization of construction waste and improving product added value.

In short, after the completion of the construction waste recycling center project, it will fill the gap in the local construction waste disposal field, achieve the reduction, harmlessness, and resource utilization of construction waste, and have great environmental significance and socio-economic benefits.
