Chaux Et Dolomies Du Boulonnais — France

Chaux Et Dolomies Du Boulonnais is a lime plant in France. Its listed capacity is 1,194,131 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 9 lime plants in France. It emits about 642,894 t CO₂e a year from Climate TRACE. That is 1.2% of the CO₂e from the 117 facilities in France 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-38467383.

In context: how this facility compares

At 1,194,131 t of lime, Chaux Et Dolomies Du Boulonnais is well above the median lime plant in France (526,987 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

Chaux Et Dolomies Du Boulonnais sits in a temperate oceanic climate zone (Köppen Cfb), at 50.8°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 1400 W/m² to ambient — roughly 1.08× 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.
