Antofagasta Cement Plant — Chile
Cement Plant in Chile. Approximate location -23.78182, -70.31906.
Cement PlantChileCO₂ estimate (modelled)
Antofagasta Cement Plant is a cement plant in Chile. 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 Cementos Bio Bio SA. It emits about 160,635 t CO₂e a year from Climate TRACE. That is 2.0% of the CO₂e from the 20 facilities in Chile that have an emissions figure in IndustryAtlas.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32437357.

In context: how this facility compares
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.

Carbon cost and Scope 1 emissions
At its reported 161k t CO₂e/yr (Scope 1), Antofagasta Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 161k t at the EU CBAM rate (€75/t) is €12.1M/yr of exposure on EU-bound exports. CBAM share rises from 2.5% (2026) to 100% by 2034. 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
Antofagasta Cement Plant sits in a cold desert climate zone (Köppen BWk), at 23.8°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 a corrosive environment (estimated ISO 9223 class C4 — High), with dust abrasion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1337 W/m² to ambient — roughly 1.03× 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.
