Construction and demolition (C&D) waste contains a large proportion of combustible materials, including wood, plastics, paper, and packaging. Improper handling of these materials can lead to:
- Increased landfill costs and site pollution
- Environmental hazards due to uncontrolled burning
- Loss of recyclable energy resources
Efficient management of combustible construction waste reduces environmental impact, recovers energy value, and supports circular economy initiatives.
Pre-Treatment: Shredding and Sorting
Proper pre-treatment of construction waste combustibles ensures safe and effective downstream processing. Recommended equipment includes:
- Double-Shaft Shredders: Ideal for bulky and mixed combustible construction waste. Reduces large pieces of wood, plastics, and composites into uniform flakes for energy recovery or further processing. Adjustable rotor speed allows adaptation to different materials.
- Single-Shaft Shredders: Designed for smaller volumes or high-density materials, providing high torque with low energy consumption.
- Trommel Screens: Remove non-combustible debris such as metals, stones, and concrete fragments. Customizable screen types ensure optimal separation efficiency.
- Magnetic Separators: Extract ferrous metals to prevent damage to downstream equipment and recover valuable resources.
Energy Recovery and Recycling Processes
Once pre-treated, construction waste combustibles can be converted into energy or secondary fuel:
- RDF/SRF Production (Refuse-Derived Fuel / Solid Recovered Fuel): Shredded combustible waste is processed into uniform-size pellets or bales for cement kilns, power plants, or industrial boilers.
- Drying and Moisture Control: Reduces moisture content to improve calorific value and combustion efficiency.
- Automated Sorting Systems: Optical and sensor-based sorting removes remaining contaminants and ensures high-quality RDF/SRF output.
Integrated Recycling and Energy Recovery Lines
For industrial-scale construction waste management, modular and automated lines offer efficiency and safety:
- Custom Modular Lines: Combine shredding, screening, magnetic separation and pelletizing in a continuous workflow.
- Automated Material Handling: Material feeders, and feeding and discharge conveyors, provide consistent material flow and high throughput.
- Process Monitoring: Real-time sensors track material composition, moisture levels, and energy output, allowing process optimization and predictive maintenance.
