Chettinad Cement Ariyalur Cement Plant — India

Chettinad Cement Ariyalur Cement Plant is a cement plant in India. Its listed capacity is 5,500,000 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 Chettinad Cement Corporation Pvt Ltd. By capacity it ranks #15 among 88 cement plants in India. It emits about 2,108,688 t CO₂e a year from Climate TRACE. That is 0.42% of the CO₂e from the 297 facilities in India that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 6% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-1896924.

In context: how this facility compares

At 5,500,000 t of cement, Chettinad Cement Ariyalur Cement Plant is well above the median cement plant in India (2,750,000 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

Chettinad Cement Ariyalur Cement Plant sits in a tropical savanna climate zone (Köppen Aw), at 11.1°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 a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1215 W/m² to ambient — roughly 0.94× 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.
