CIRCULAR ECONOMY TALK - Refuse Derived Fuel (RDF) processing with Zero Waste Group - SPALECK CET

SPALECK CIRCULAR ECONOMY TALK: Efficient RDF processing in Hungary – plant engineering, materials handling, and screening precision in practice

In this Circular Economy Talk, we visit the Zero Waste Group in Hungary. The team shares its approach to modern RDF processing – including pre-shredding, screening, metal separation, air classification, and fine shredding.

At the heart of the line: a tailored SPALECK screening machine designed to handle highly variable, moisture-prone RDF input and deliver consistent output fractions. Learn how the plant was built from the ground up and how the process was optimized for flexibility, durability, and throughput reliability.

This CET provides practical insights into process engineering for waste-to-energy applications, with a clear focus on material consistency, downstream equipment protection, and system uptime.

🔍 Key focus areas of this CET episode

▶️ RDF processing from input to high-quality fuel
→ End-to-end insights: From feedstock reception to final 2D fuel fraction – powered by SPALECK screening systems.

▶️ Consistent particle sizes (0–30 mm & 30–150 mm) for downstream process efficiency
→ Ensures optimal performance of air separators, shredders, and material handling – key for plant stability.

▶️ Efficient screening of wet and inconsistent RDF materials with SPALECK technology
→ Reliable classification despite moisture and input fluctuation – ensures uptime and material purity.

▶️ Extended shredder knife life through pre-screening with SPALECK
→ Removes fines and abrasives early – reduces wear, saves costs, and prolongs maintenance intervals.

▶️ Plant design with built-in flexibility, redundancy, and future capacity
→ SPALECK modular design approach supports scaling, layout optimization, and operational resilience.

▶️ Live plant diagnostics & predictive maintenance in RDF operations
→ Real-time performance insights with mobile monitoring and sensor feedback – fewer surprises, more control.

▶️ RDF market outlook: Securing domestic supply and building export capacity
→ How future-ready RDF production plants ensure competitiveness in volatile waste-to-energy markets.
