Aluminium Oxid Stade GmbH (AOS) Alumina Refinery

Aluminium Oxid Stade GmbH (AOS) Alumina Refinery is an aluminium smelter in Germany with a reported capacity of 1,100,000 t of alumina/aluminum. It smelts alumina into primary aluminium by high-current electrolysis. It is operated by DADCO Alumina & Chemicals . By capacity it ranks #1 of 6 aluminium smelters tracked in Germany. It emits about 1,278,896 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 298,111 cars. Its CO₂ per unit of capacity is about 44% below the median aluminium smelter.

Im Kontext: wie sich diese Anlage vergleicht

Bei 1,100,000 t of alumina/aluminum ist Aluminium Oxid Stade GmbH (AOS) Alumina Refinery deutlich über dem Medianwert von aluminium smelter in Germany (85,000 t of alumina/aluminum). Sein CO₂ pro Kapazitätseinheit liegt ungefähr 46% unter dem Medianwert von aluminium smelter. Untersektor: aluminum. Als aluminium smelter benötigt es intensive Prozesswärme (typischerweise 600–900°C) für seinen Kernbetrieb — Wärme, die durch Dampfkessel, Öfen oder direkte Verbrennung geliefert werden muss, und Verluste durch ungedämmte Behälter und Rohrleitungen stellen verschwendeten Brennstoff dar. Modulare abnehmbare Dämmung kann diese Verluste um 80–96% senken, Oberflächen auf ≤45°C kühlen, mit Amortisationszeiten oft unter 2 Jahren. Aluminiumhütten nutzen große Elektroströme, um Tonerde in geschmolzenes Aluminium über 900°C zu raffinieren, und das heiße Metall muss durch Tiegel und Gießausrüstung fließen.
