Sinar Tambang Arthalestari Banyumas Cement Plant — Indonesia

Sinar Tambang Arthalestari Banyumas Cement Plant is a cement plant in Indonesia. Its listed capacity is 5,000,000 t of cement. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length. It is operated by PT Sinar Tambang Arthalestari. By capacity it ranks #6 among 16 cement plants in Indonesia. It emits about 1,228,973 t CO₂e a year from Climate TRACE. That is 1.7% of the CO₂e from the 53 facilities in Indonesia that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 32% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32438513.

In context: how this facility compares

At 5,000,000 t of cement, Sinar Tambang Arthalestari Banyumas Cement Plant is around the median cement plant in Indonesia (4,300,000 t of cement). Subsector: cement. As cement plant, it requires high process heat (typically 800–1400°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Cement plants heat limestone to 1,400°C in rotary kilns — one of the hottest industrial processes — and must control temperature precisely across the entire kiln length.

Local climate

Sinar Tambang Arthalestari Banyumas Cement Plant sits in a tropical rainforest climate zone (Köppen Af), at 7.4°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 1235 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.
