The production of construction waste in China has reached the order of one billion tons. Some people believe that China's construction waste production will reach about 3.5 billion tons in 2024, and is expected to exceed 4 billion tons by 2026. By 2030, this number will climb to about 6 billion tons.

Although the resource utilization rate of construction waste in China has been increasing year by year, there is still a significant gap compared to developed countries. At present, the resource utilization rate of construction waste in China is less than 5%, while the recycling rate of construction waste in some developed countries has reached over 90%.

After sorting, crushing, screening and other processes, construction waste can be processed into recycled aggregates of different specifications, which can be used for laying foundations, preparing recycled concrete, producing refractory bricks, etc. In addition, the waste bricks and tiles in construction waste can be used to produce recycled building materials such as bricks and blocks. Waste wood based construction waste can be reused for rebuilding buildings or as raw materials for papermaking. Waste road asphalt mixture can be directly used for recycled asphalt concrete in appropriate proportions.

At present, Chinese construction waste treatment enterprises have widely used equipment such as crushers, screening machines, and mixers to process construction waste and produce high-quality recycled aggregates and building materials products.

The current situation of China's construction waste recycling presents characteristics such as huge production volume, continuous growth of market size, gradual improvement of resource utilization rate, continuous improvement of policies and regulations, and continuous advancement of technology and equipment. However, the industry still faces many challenges and issues that need to be addressed. In the future, with the continuous advancement of technology and the continuous promotion of policies, China's construction waste recycling industry will usher in a more prosperous period of development.
