Puerto Madryn aluminium plant — Argentina
Aluminium Smelter in Argentina. Approximate location -42.73902, -65.05338.
Aluminium SmelterArgentinaCO₂ estimate (modelled)
Puerto Madryn aluminium plant is an aluminium smelter in Argentina. Its listed capacity is 287,000 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. It is operated by Aluar. It emits about 644,987 t CO₂e a year from Climate TRACE. That is 3.1% of the CO₂e from the 33 facilities in Argentina that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 8% above the national median for this sector.

In context: how this facility compares
At 287,000 t of alumina/aluminum, Puerto Madryn aluminium plant is around the median aluminium smelter in Argentina (287,000 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.

Carbon cost and Scope 1 emissions
At its reported 645k t CO₂e/yr (Scope 1), Puerto Madryn aluminium plant carries no domestic carbon price — and as a CBAM-covered product, its 645k t at the EU CBAM rate (€75/t) is €48.6M/yr of exposure on EU-bound exports. CBAM share rises from 2.5% (2026) to 100% by 2034. No domestic carbon price — but cement, steel, aluminium, fertilizer and hydrogen exported to the EU face CBAM at €75/t (rising to 100% by 2034).

Local climate
Puerto Madryn aluminium plant sits in a cold semi-arid steppe climate zone (Köppen BSk), at 42.7°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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1364 W/m² to ambient — roughly 1.05× 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.

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.
