Gunung Raja Paksi West Java steel plant — Indonesia

Gunung Raja Paksi West Java steel plant is a steel plant in Indonesia. Its listed capacity is 2,800,000 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 PT Gunung Raja Paksi Tbk. By capacity it ranks #3 among 5 steel plants in Indonesia. It emits about 1,748,129 t CO₂e a year from Climate TRACE. That is 2.4% of the CO₂e from the 53 facilities in Indonesia that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 33% below the national median for this sector.

In context: how this facility compares

At 2,800,000 t of steel, Gunung Raja Paksi West Java steel plant is around the median steel plant in Indonesia (2,800,000 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

Gunung Raja Paksi West Java steel plant sits in a tropical rainforest climate zone (Köppen Af), at 6.3°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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1238 W/m² to ambient — roughly 0.95× 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.
