Mariel Cement Plant

Mariel Cement Plant is a cement plant in Cuba with a reported capacity of 1,000,000 t of cement. It burns limestone in high-temperature rotary kilns to make clinker and cement. It is operated by Empresa Mixta Cementos Curazao SA. By capacity it ranks #2 of 4 cement plants tracked in Cuba. It emits about 330,718 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 77,090 cars. Its CO₂ per unit of capacity is about 8% below the median cement plant.

Im Kontext: wie sich diese Anlage vergleicht

Bei 1,000,000 t of cement ist Mariel Cement Plant etwa um dem Medianwert von cement plant in Cuba (1,000,000 t of cement). Sein CO₂ pro Kapazitätseinheit liegt ungefähr 9% unter dem Medianwert von cement plant. 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.
