Nordkalk Oyj Abp, Raahen Kalkinpolttamo — Finland

Nordkalk Oyj Abp, Raahen Kalkinpolttamo is a lime plant in Finland. Its listed capacity is 180,440 t of lime. Lime plants calcine limestone in kilns at 800–900°C; the quicklime they produce reacts with moisture and has to be kept dry. By capacity it ranks #1 among 6 lime plants in Finland. It emits about 170,587 t CO₂e a year from Climate TRACE. That is 1.4% of the CO₂e from the 28 facilities in Finland that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 44% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-38467379.

In context: how this facility compares

At 180,440 t of lime, Nordkalk Oyj Abp, Raahen Kalkinpolttamo is around the median lime plant in Finland (166,642 t of lime). Subsector: lime. As lime plant, it requires high process heat (typically 600–900°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Lime plants calcine limestone in kilns at 800–900°C; the quicklime they produce reacts with moisture and has to be kept dry.

Local climate

Nordkalk Oyj Abp, Raahen Kalkinpolttamo sits in a subarctic (boreal) climate zone (Köppen Dfc), at 64.7°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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with marine corrosion the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1479 W/m² to ambient — roughly 1.14× 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.
