The disposal of construction waste is a complex but vital process that aims to reduce environmental pollution, achieve resource reuse, and promote sustainable development. The following is a detailed introduction to the Waste Sorting Star Screen method:

1. Source reduction and classified collection

1. Source reduction: In the building design and construction stage, priority should be given to the use of easily recycled or renewable materials to reduce unnecessary waste and improve the efficiency of material use. At the same time, formulate construction waste reduction targets, and specify reduction measures in the construction plan.

2. Classification collection: Special classification collection containers are set up at the construction site, and preliminary classification is carried out according to different properties of materials, such as concrete, masonry, metal, wood, etc. Use intelligent sorting garbage cans or RFID tags to assist workers in correctly classifying and placing.

Second, resource utilization

1. Recycled aggregate production: the processed inorganic materials such as concrete blocks and bricks are used as recycled aggregate for the production of new building materials, such as recycled concrete and recycled bricks. This can not only reduce the need for new raw materials, but also reduce production costs.

2. Recycling: For valuable materials such as metal and wood, recycling should be carried out. These materials can be processed to make new products or used as raw materials for other industries.

3. Energy utilization: For construction waste that cannot be directly reused, high temperature incineration and other technologies can be considered for energy utilization. The heat generated through incineration can be converted into electricity or heat, providing renewable energy for the city.

Third, landfill and incineration treatment

1. Landfill treatment: For construction waste that cannot be reused as resources, appropriate landfill sites should be selected for landfill treatment. In the process of landfill, it should be ensured that the site selection, design, construction and operation of the landfill meet the relevant environmental requirements to prevent harm to the environment and human health.

2. Incineration treatment: Although incineration treatment can reduce the volume of waste and recover energy, it may also produce pollutants such as harmful gases and carbon dioxide. Therefore, when selecting the incineration treatment method, its environmental impact should be fully considered, and effective pollution control measures should be taken.

Fourth, strengthen supervision and law enforcement

1. Improve laws and policies: establish and improve the legal and policy system of construction waste management, and clarify the responsible subjects and regulatory requirements of various links such as the generation, collection, transportation and disposal of construction waste.

2. Strengthen law enforcement: Increase the investigation and punishment of illegal acts of construction waste, severely punish violations, and ensure the compliance and standardization of construction waste management.
