Sampyo Cement Samcheok Cement Plant — South Korea

Sampyo Cement Samcheok Cement Plant is a cement plant in South Korea. Its listed capacity is 10,090,000 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 Sampyo Cement Co Ltd. By capacity it ranks #2 among 9 cement plants in South Korea. It emits about 3,255,726 t CO₂e a year from Climate TRACE. That is 2.1% of the CO₂e from the 51 facilities in South Korea that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 11% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32438853.

In context: how this facility compares

At 10,090,000 t of cement, Sampyo Cement Samcheok Cement Plant is well above the median cement plant in South Korea (4,410,000 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

Sampyo Cement Samcheok Cement Plant sits in a humid subtropical climate zone (Köppen Cfa), at 37.4°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 humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1392 W/m² to ambient — roughly 1.07× 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.
