Background
The construction waste refers to the residual waste soil, waste material, residual soil, residual mud and other wastes left in the process of laying, constructing or dismantling various buildings, structures and the like by individuals, construction units or construction units. The yield of the construction waste in China increases year by year, the composition of the construction waste is complex, and the waste components generated by buildings of different times and different structure types are different. In 3 months in 2021, the national development and reform Commission unites nine departments to issue a file about the comprehensive utilization of a large amount of solid wastes, clearly stipulates that the comprehensive utilization rate of the large amount of newly added solid wastes reaches 60% in 2025, pushes out green construction in the engineering construction field, promotes waste pavement materials and removes in-situ regeneration and utilization of wastes, implements classification management, source reduction, resource utilization and the like of construction wastes. The utilization quality is continuously improved, and the utilization scale is improved. The annual output of the building garbage in China is 30.39 hundred million tons in 2020, and the annual output of the building garbage is increased by 11.32 percent in the last year. The utilization rate of developed countries in Europe and America is more than 95%, and the recycling degree of the construction waste resources in China is lower. In 2018, along with the successive departure of relevant policies and the development of urban pilot points, the speed of the construction waste recycling process is increased. In 35 pilot cities in the country by the end of 2020, about 600 construction waste recycling treatment items exist, the recycling treatment capacity reaches 5.5 million tons per year, but only 3.5 million tons of construction waste which actually realizes resource utilization exist, and the utilization rate is only about 10%. If the construction waste is completely converted into the recycled construction material, trillion yuan value can be created, and the comprehensive treatment and recycling of the construction waste can be a huge market.
