CSN Cimentos Brasil Cantagalo Plant — Brazil

CSN Cimentos Brasil Cantagalo Plant is a cement plant in Brazil. Its listed capacity is 900,000 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 CSN Cimentos Brasil SA. By capacity it ranks #20 among 31 cement plants in Brazil. It emits about 417,073 t CO₂e a year from Climate TRACE. That is 0.30% of the CO₂e from the 130 facilities in Brazil that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 28% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32437304.

In context: how this facility compares

At 900,000 t of cement, CSN Cimentos Brasil Cantagalo Plant is around the median cement plant in Brazil (1,080,000 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

CSN Cimentos Brasil Cantagalo Plant sits in a tropical savanna climate zone (Köppen Aw), at 21.9°S in the southern 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 1285 W/m² to ambient — roughly 0.99× 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.
