Stora Enso Oyj - Varkaus Mill — Finland

Stora Enso Oyj - Varkaus Mill is a pulp & paper mill in Finland. Its listed capacity is 331,200 t of pulp & paper. Pulp and paper mills generate their own steam for the pulping process and paper dryers, running large-scale boiler systems where heat loss directly reduces efficiency. It is operated by Stora Enso Oyj. By capacity it ranks #11 among 13 pulp & paper mills in Finland. It emits about 146,749 t CO₂e a year from Climate TRACE. That is 1.2% of the CO₂e from the 28 facilities in Finland that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 18% below the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-44375532.

In context: how this facility compares

At 331,200 t of pulp & paper, Stora Enso Oyj - Varkaus Mill is below the median pulp & paper mill in Finland (642,628 t of pulp & paper). Subsector: pulp-and-paper. As pulp & paper mill, it requires high process heat (typically 150–250°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Pulp and paper mills generate their own steam for the pulping process and paper dryers, running large-scale boiler systems where heat loss directly reduces efficiency.

Local climate

Stora Enso Oyj - Varkaus Mill sits in a subarctic (boreal) climate zone (Köppen Dfc), at 62.3°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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1470 W/m² to ambient — roughly 1.13× 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.
