Ryukyu Cement Nago Cement Plant

Ryukyu Cement Nago Cement Plant is a cement plant in Japan with a reported capacity of 650,000 t of cement. It burns limestone in high-temperature rotary kilns to make clinker and cement. It is operated by Ryukyu Cement Co Ltd. By capacity it ranks #26 of 27 cement plants tracked in Japan. It emits about 245,696 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 57,272 cars. Its CO₂ per unit of capacity is about 5% above the median cement plant.

Im Kontext: wie sich diese Anlage vergleicht

Bei 650,000 t of cement ist Ryukyu Cement Nago Cement Plant unter dem Medianwert von cement plant in Japan (1,890,000 t of cement). Untersektor: cement. Als cement plant benötigt es intensive Prozesswärme (typischerweise 800–1400°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. Zementanlagen erhitzen Kalkstein auf 1.400°C in Drehrohröfen — einer der heißesten Industrieprozesse — und müssen die Temperatur über die gesamte Ofenlänge präzise kontrollieren.
