Sider El Hadjar Annaba steel plant — Algeria

Sider El Hadjar Annaba steel plant is a steel plant in Algeria. Its listed capacity is 2,500,000 t of steel. Steel plants burn coal in blast furnaces or use electric arcs to melt scrap; in both cases the molten metal must be kept above 1,500°C and transferred through extensive hot piping and vessels. It is operated by Groupe Industriel Sider SpA. By capacity it ranks #2 among 2 steel plants in Algeria. It emits about 951,644 t CO₂e a year from Climate TRACE. That is 4.7% of the CO₂e from the 29 facilities in Algeria that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 59% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32440720.

In context: how this facility compares

At 2,500,000 t of steel, Sider El Hadjar Annaba steel plant is below the median steel plant in Algeria (4,857,377 t of steel). Subsector: iron-and-steel. As steel plant, it requires high process heat (typically 800–1500°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Steel plants burn coal in blast furnaces or use electric arcs to melt scrap; in both cases the molten metal must be kept above 1,500°C and transferred through extensive hot piping and vessels.

Local climate

Sider El Hadjar Annaba steel plant sits in a hot-summer Mediterranean climate zone (Köppen Csa), at 36.8°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 corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1320 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.
