Bulky Waste Disposal

Bulky Waste Disposal Plant

Waste that doesn't fit in the trash is considered "bulky waste".
This includes mainly discarded furniture, mattresses, wallpaper remnants, and old carpets. Today, most bulky waste can be recycled for materials and energy.

Bulky Waste Disposal Process:

1. Pre-shredding: Bulky waste (such as used furniture, mattresses, and wood) is conveyed to a single-shaft shredder (or dual-shaft shredder). Low-speed, high-torque blades (or cutters) shred large items (such as sofas and bed frames) into medium-sized pieces of 30-50 cm. This eliminates the problem of large-volume entanglement, reduces energy consumption for subsequent processing, and provides an appropriate particle size for fine crushing.
2. Fine Shredding and Sorting: Medium-sized items are conveyed via belt to a fine shredder (such as a single-shaft or dual-shaft shredder) for further shredding to 5-10 cm (or even smaller, 1-5 cm, depending on RDF/SRF requirements). Subsequently, magnetic separation (to recover residual metals) and air separation (to separate lightweight plastics/fabrics from heavy inert materials) are used to retain high-calorific value combustible components (such as pure wood, fiber, and plastic).
3. RDF/SRF Preparation: The sorted combustibles are then compressed into rod-shaped fuel (RDF) using an RDF machine; or they can be made into SRF (solid recovered fuel), which can directly replace coal.
This process utilizes a combination of coarse crushing, sorting, fine crushing, and forming to transform bulky waste into high-value-added fuel. A single-shaft shredder, as the core front-end equipment, significantly improves subsequent processing efficiency and resource recovery.
