Puerto Madryn aluminium plant

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, roughly comparable to the annual emissions of 150k passenger cars. 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 — heat that must be supplied by boilers, furnaces or direct combustion, and losses through uninsulated vessels and piping represent wasted fuel. Removable modular insulation can cut those losses by 80–96%, surface-cooling equipment to ≤45°C, with payback often under 2 years. 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, Scope 1 & decarbonization potential

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. The fastest decarbonization lever is energy efficiency: eliminating heat loss on hot equipment (removable insulation, steam & waste-heat recovery) typically cuts 2–5% of fuel-related CO₂ — here ≈13k t–32k t/yr, worth €972k€2.4M, with payback up to 2 years. 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.

Site climate & environmental severity

The local climate sets how fast unprotected steel, protective coatings and the insulation on hot process equipment degrade at this site. It 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; removable insulation recovers about 1296 W/m² of that. 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).

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.

Heat loss & insulation profile

For a aluminium smelter, the main modular-insulation targets are alumina calciner, casthouse furnaces, hot ducting (electrolysis itself is electric). Typical hot-surface ranges used for screening: 150–1,000 °C.

electrolysis is mostly electricity (Scope 2) + anode process; on-site combustion small - insulation mainly relevant to alumina refining/casthouse.

Indicative recoverable energy

A first-pass insulation screen suggests about 2,200 MWh/year of recoverable heat-loss reduction and about 440 t CO₂e/year of avoided emissions. Screening estimate scaled from installed process-heat projects and surface-temperature reduction data.

Safety & the no-regret first step

Start with a thermal survey of valves, flanges, doors and bends. Removable modular insulation keeps maintenance access open while lowering exposed-surface temperature and wasted heat.
