High Calorific Value = Cost Savings

Dry-base calorific value: ~5,000 × 4.18 kJ/kg

Pure polyester textiles: 5,500 kcal/kg (comparable to lignite)

Blended fabrics: >4,000 kcal/kg

Average combustion value: 4,500–5,000 kcal/kg (75% of coal)

When supplied to cement plants, waste textiles significantly reduce coal consumption and procurement costs.

HARDEN's Solution: High-Efficiency RDF/SRF Production

With over a decade of expertise in waste processing, Harden Machinery Ltd. delivers an optimized solution for converting waste textiles into high-calorific RDF/SRF.

Core Concept: "Finer Shredding, Faster Sorting, More Precise Separation"

Guided by this principle, HARDEN has developed a dedicated textile RDF/SRF production system, offering higher efficiency and precision for industrial waste processing.

Key Applications

The system processes:

✔ Waste textiles (discarded clothing, fabric scraps)

✔ Leather offcuts

✔ Waste plastics & other general industrial waste

Advanced Processing: "Shredding + Air Classification + Magnetic Separation"

Primary shredding → Metal/heavy material removal

Fine shredding → Final RDF/SRF size: 30–80 mm

The Future of Industrial Waste: Reduce, Reuse, Recover

Converting waste textiles, leather, and plastics into high-energy RDF/SRF represents a sustainable shift in industrial waste management:

✅ Cost savings (reduced fossil fuel dependency)

✅ Major carbon footprint reduction

HARDEN is driving the transition toward zero-waste, low-carbon industrial production.
