1. Pain points of traditional demolition: high cost and low efficiency of construction waste treatment
In the process of urban renewal and demolition, the treatment of construction waste has always been a problem that troubles the construction party.
1.1 Traditional methods usually include:
• Manual sorting + external landfill
• A large amount of manpower is required to sort recyclable materials
• Transportation costs account for more than 30% of the total project cost
• Freight costs increase exponentially when the landfill is far away
1.2 Fixed crushing station treatment
• Garbage needs to be transported to a fixed site
• Secondary transportation incurs additional costs
• Site rental and equipment construction are time-consuming and labor-intensive
Data comparison: A demolition project in a second-tier city shows that the proportion of transportation costs in traditional methods is as high as 38%, while the use of mobile crushing stations can be reduced to 19%.
2. Innovative solution: on-site processing technology of mobile crushing stations
2.1 Technical principle
The mobile crushing stationis an intelligent equipment that integrates feeding, crushing, screening and transportation, and can be directly driven to the demolition site for operation.
2.11 Core advantages:
• Modular design: crawler/tire mobile, flexible transfer
• Multi-stage crushing system: jaw crusher + impact crusher/cone crusher combination, suitable for different materials such as reinforced concrete, brick-concrete structure
• Intelligent sorting device: automatic separation of metal, wood and other impurities
2.2 Key points of cost saving
Cost item Traditional method Mobile crushing station solution Savings ratio
• Transportation fee 1 million yuan 500,000 yuan 50%
• Landfill fee 300,000 yuan 0 yuan (recycling) 100%
• Labor cost 200,000 yuan 120,000 yuan 40%
Case: A village renovation project in Zhengzhou used a mobile crushing station to process 80,000 tons of construction waste on site, saving more than 3 million yuan in transportation costs.
3. Environmental protection and economic benefits
3.1 Environmental benefits
• Reduce carbon emissions: On-site treatment of every 10,000 tons of construction waste can reduce transportation carbon emissions by about 15 tons
• Resource recycling: Crushed aggregates can be used for:
✓ Road cushion (RAP material)
✓ Recycled brick raw materials
✓ Concrete mixing station auxiliary materials
3.2 Economic benefits
• Government subsidies: Many places provide 10-30 yuan per ton of subsidies for construction waste resource projects
• Recycled material benefits: The market price of high-quality aggregates can reach 80-120 yuan/ton
4. Implementation suggestions
4.1 Equipment selection
• Small and medium-sized projects: Choose a tire-type mobile station with an output of 100-200 tons per hour
• Large-scale renovation: Configure a crawler crushing and screening combined unit with an output of more than 500 tons per hour
4.2 Policy docking
• Pre-register the "Construction Waste Resource Disposal Plan"
• Apply for green construction demonstration project qualifications
4.3 Operation skills
• Adopt "day and night" operation mode (demolition during the day and crushing at night)
• Sign a long-term aggregate supply agreement with the local mixing station
5. Industry trend outlook
With the advancement of the "14th Five-Year Plan for Comprehensive Management of Construction Waste", the market size of mobile crushing stations is expected to grow by 18% annually in the next three years. Cities such as Beijing and Shanghai have clearly required that the recycling rate of construction waste in new projects starting from 2025 should not be less than 60%.
