Poços de Caldas Municipality — Brazil

Poços de Caldas Municipality is an aluminium smelter in Brazil. Its listed capacity is 141,756 t of alumina/aluminum. Aluminium smelters use large electric currents to refine alumina into molten aluminium above 900°C, and the hot metal must flow through crucibles and casting equipment. By capacity it ranks #6 among 6 aluminium smelters in Brazil. It emits about 235,385 t CO₂e a year from Climate TRACE. That is 0.17% of the CO₂e from the 130 facilities in Brazil that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 21% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3672957.

In context: how this facility compares

At 141,756 t of alumina/aluminum, Poços de Caldas Municipality is below the median aluminium smelter in Brazil (480,000 t of alumina/aluminum). Subsector: aluminum. As aluminium smelter, it requires high process heat (typically 600–900°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Aluminium smelters use large electric currents to refine alumina into molten aluminium above 900°C, and the hot metal must flow through crucibles and casting equipment.

Local climate

Poços de Caldas Municipality sits in a humid subtropical climate zone (Köppen Cfa), at 21.8°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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1316 W/m² to ambient — roughly 1.01× 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.
