Construction waste disposal process

Construction waste disposal refers to the process of collecting, transporting, treating, and utilizing waste generated during construction, demolition, decoration, and other processes.

1. Collection and classification

Collection: Set up specialized construction waste collection points at construction sites or demolition sites for centralized collection.

Classification: Classify the collected construction waste, including:

♻️ Recyclable materials: such as steel bars, metal, wood, bricks, etc.

♻️ Non recyclable materials: such as concrete, gypsum board, ceramics, etc.

♻️ Hazardous waste: such as building materials containing harmful substances (such as asbestos, paint, etc.).

2. Transportation

Transport vehicles: Use specialized transport vehicles to transport construction waste from the construction site to the disposal site. Transport vehicles need to be sealed to avoid garbage spillage and secondary pollution.

Transportation management: Ensure that the transportation process meets environmental requirements and avoids any impact on the surrounding environment.

3. Preprocessing

Crushing and screening: Crushing construction waste to reduce its volume and divide it into smaller particles for subsequent processing. Separate different materials through screening equipment.

Sorting: Use manual and mechanical means to further sort construction waste, separating recyclable materials from non recyclable materials.

4. Resource utilization

recycling:

♻️ Recyclable materials, such as metal, wood, plastic, etc., can be processed into new products or used in other buildings.

♻️ Recycled aggregate: Processing renewable materials such as concrete and bricks to produce recycled aggregate for the production of new concrete or other construction projects.

♻️ Hazardous waste disposal: Professional treatment of hazardous waste to prevent harm to the environment and human health.

5. Disposal

‼️ Landfill: Construction waste that cannot be recycled needs to be landfilled. Landfills must comply with environmental standards to avoid polluting soil and water sources.

‼️ Incineration: Some hazardous construction waste can be incinerated to reduce its volume and convert it into heat and electricity.

6. Monitoring and evaluation

Environmental monitoring: Monitor the waste gas, wastewater, noise, etc. generated during the treatment process to ensure compliance with environmental protection requirements.

Effect evaluation: Regularly evaluate the effectiveness of construction waste treatment, including recycling rate, resource utilization rate, and environmental impact.
