Malayan Cement Rawang Cement Plant — Malaysia

Malayan Cement Rawang Cement Plant is a cement plant in Malaysia. Its listed capacity is 2,500,000 t of cement. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length. It is operated by Malayan Cement Bhd. By capacity it ranks #3 among 6 cement plants in Malaysia. It emits about 1,002,324 t CO₂e a year from Climate TRACE. That is 2.3% of the CO₂e from the 39 facilities in Malaysia that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 11% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32438946.

In context: how this facility compares

At 2,500,000 t of cement, Malayan Cement Rawang Cement Plant is around the median cement plant in Malaysia (2,500,000 t of cement). Subsector: cement. As cement plant, it requires high process heat (typically 800–1400°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length.

Local climate

Malayan Cement Rawang Cement Plant sits in a tropical rainforest climate zone (Köppen Af), at 3.3°N in the northern hemisphere.

Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).

Site climate & environmental severity

This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1230 W/m² to ambient — roughly 0.95× the loss at a 20 °C reference. Reference-surface calculation at a 150 °C surface from WorldClim climate normals (ASTM C680 / ISO 12241) — an indicative per-climate comparison, not a measurement of this site’s specific equipment. Open method dataset: DOI 10.5281/zenodo.20787408 (CC BY 4.0).

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
