Ziar nad Hronom aluminium plant — Slovakia

Ziar nad Hronom aluminium plant is an aluminium smelter in Slovakia. Its listed capacity is 70,000 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 Slovak Aluminium Co. It emits about 153,092 t CO₂e a year from Climate TRACE. That is 1.4% of the CO₂e from the 19 facilities in Slovakia that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 5% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-3673136.

In context: how this facility compares

At 70,000 t of alumina/aluminum, Ziar nad Hronom aluminium plant is around the median aluminium smelter in Slovakia (70,000 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

Ziar nad Hronom aluminium plant sits in a warm-summer humid continental climate zone (Köppen Dfb), at 48.6°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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1431 W/m² to ambient — roughly 1.10× 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.
