一.Economic benefits level

1.Reduce disposal costs

*After sorting construction waste, profits can be generated by selling recycled materials. For example, the price of recycled aggregate is about 50% to 70% of natural aggregates, but the production cost is lower and the profit margin is considerable.

*For construction companies, reduce waste removal and landfill costs while obtaining additional revenue from the sale of recyclables。

2.Drive the development of the industrial chain

*It has spawned emerging industries such as construction waste sorting equipment manufacturing, recycled material processing, resource recycling and utilization, and created jobs (such as equipment operation, sorting, transportation, etc.).

*Case: The annual processing volume of a construction waste treatment project in a certain city is 5 million tons, which can create more than 500 direct jobs, driving the output value of related industries to grow by hundreds of millions of yuan.

二.Social and policy benefits

1.Improve urban management level

*Standardize the sorting process of construction waste, curb the chaos such as illegal dumping and arbitrary stacking, and improve the level of urban environmental sanitation and refined management

*Provide support for the implementation of policies such as “waste-free cities” and “sponge cities” and are in line with the national “dual carbon” goals and green development orientation.

2.Enhance public awareness of environmental protection

*Through the publicity and practice of construction waste sorting, the public can be enhanced to reuse resources and promote the popularization of green lifestyles.

三Technology and process advantages

1.Mature and diverse sorting techniques

*It can adopt various methods such as physical sorting (screening, magnetic sorting, gravity sorting), optical sorting (intelligent identification sorting), and manual sorting to adapt to different garbage components and treatment scales.

*.Intelligent equipment (such as construction waste sorting production lines) can achieve automated sorting, improve efficiency and reduce labor costs.

2.High processing efficiency and flexibility

*Large-scale sorting projects can achieve the treatment of thousands of tons of construction waste every day to meet the needs of rapid urban development; small equipment can be used for on-site sorting on construction sites to reduce transportation costs.

Summary: Construction waste sorting is the core means to crack the “garbage siege” and realize resource recycling, and its advantages run through multiple dimensions of resources, environment, economy and society. With the increasing policy support and technological progress, construction waste sorting will become an important part of the green building materials industry and provide strong support for sustainable development. In the future, we need to further promote sorting technology innovation and improve the standard system of recycled materials to enhance the synergy effect of the entire industrial chain.
