BLK – Bulky Waste Shredding Plant

Bulky waste shredding plants are engineered to process large, heavy, and irregularly shaped items that are challenging for standard waste collection and processing systems to handle. These facilities use robust shredding equipment to break down bulky materials into manageable sizes, improving handling, reducing landfill space requirements, and enabling more efficient recycling or energy recovery.

Bulky Waste Shredding Process

1. Collection and Feeding
Bulky waste is gathered from collection points and transported to a central sorting or transfer station. Using cranes or excavators, the material is loaded onto heavy-duty conveyors, which feed it steadily into the shredder.

2. Primary Shredding
Large and irregular items such as mattresses, sofas, and wooden furniture are broken down using high-power, low-speed double- or three-shaft shredders. The waste is reduced to uniform pieces (e.g., 60mm x 60mm), minimizing volume and preparing it for further processing.

3. Material Separation
Shredded fragments move to separation systems to recover valuable materials:

  • Magnetic Separation: Extracts ferrous metals like iron, steel springs, nails, and wires for recycling.
  • Optional Advanced Separation: Air classifiers and eddy current separators remove light materials and recover non-ferrous metals, improving material quality and recycling efficiency.

4. Post-Processing and Disposal
The remaining mix of wood, textiles, plastics, and foam is reduced in volume and homogenized.

  • Energy Recovery: Fragments can be used as Refuse-Derived Fuel (RDF) or Solid Recovered Fuel (SRF) for energy generation.
  • Compaction: Material may be baled for efficient storage and transport to landfills or waste-to-energy facilities.
  • Dust Control: Integrated pulse dust collection systems maintain a clean and safe working environment.

Key Functions and Benefits

  • Volume Reduction: Shredding significantly decreases the volume of bulky waste, reducing transportation costs and optimizing landfill utilization.
  • Material Recovery: The shredding process facilitates the separation of valuable materials such as metals, wood, and foam. These recovered materials can be recycled or reused, generating economic value while conserving natural resources.
  • Homogenization: Reducing waste to smaller, more uniform pieces improves consistency in density and composition. This uniformity enhances the efficiency of downstream processing, including use as Refuse-Derived Fuel (RDF) or other recycling applications.
  • Types of Waste Processed: Bulky waste shredding plants can handle a wide variety of materials, including:

    1) Discarded furniture such as sofas and chairs
    2) Old mattresses
    3) Large household appliances
    4) Construction and demolition debris
    5) Industrial and municipal solid waste (MSW)
