Summary
SKAPA Recycling GmbH operates a closed-loop system that turns used aluminum cans into new raw material for can production and other products. This process saves up to 95% of energy, reduces CO₂ emissions, and keeps valuable aluminum in the economy.
Description:
SKAPA Recycling GmbH is a specialized SME based in Kottingbrunn, Austria, focused on aluminum recycling, particularly of used beverage cans (UBCs). In a country known for its high recycling rates—where 100% of household steel cans are recycled when properly collected—SKAPA contributes by enabling a closed-loop aluminum system. The company transforms post-consumer aluminum packaging into secondary raw material for new cans and other high-quality products, demonstrating how SMEs can anchor national circular systems. SKAPA operates as a collection and reprocessing hub for aluminum packaging waste, integrated with Austria’s “Gelber Sack” (yellow bag) household collection system. Their process includes: ¡ Sorting and Pre-treatment: Collected UBCs are sorted, cleaned, and shredded. Advanced systems remove contaminants like labels, plastic liners, or adhesives. ¡ Remelting and Refining: Shredded aluminum is remelted into ingots or billets, which are then supplied to aluminum manufacturers—often for producing new cans, bicycle frames, or automotive components. ¡ Material Circularity: This enables can-to-can recycling, creating a fully closed material loop where the same aluminum can be reused indefinitely without quality degradation. Page 31 ¡ Volume Handled: Austria generates ~12,000 tonnes of aluminum beverage cans per year, with 5,000– 8,000 tonnes channeled through recyclers like SKAPA. Their operations help ensure that high-value aluminum remains in productive use within Austria or is exported in ready-to-use form.

Economic Perspective
SKAPA’s business model proves that circularity can generate strong economic returns: ¡ High Market Value of Output: Recycled aluminum retains ≥90% of primary market value, making it a profitable secondary material. ¡ Cost Advantage for Buyers: Recycled ingots are typically cheaper than primary aluminum—especially under high energy prices—making them attractive for manufacturers. ¡ Revenue Model: SKAPA earns income from processing contracts and by selling specification-grade aluminum to can producers and other manufacturers. ¡ System-Wide Savings:
