Solvay Sodi Devnya Soda Ash Plant — Bulgaria

Solvay Sodi Devnya Soda Ash Plant is a chemical plant in Bulgaria. Chemical plants produce a wide range of industrial and specialty chemicals, many requiring precise temperature control and sustained heat input for reactions and separations. It is operated by Solvay Sodi AD. It emits about 529,204 t CO₂e a year from Climate TRACE. That is 12% of the CO₂e from the 10 facilities in Bulgaria that have an emissions figure in IndustryAtlas.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-45257185.

In context: how this facility compares

Subsector: chemicals. As chemical plant, it requires high process heat (typically 100–500°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Chemical plants produce a wide range of industrial and specialty chemicals, many requiring precise temperature control and sustained heat input for reactions and separations.

Capacity & CO₂-intensity comparison computed from Climate TRACE industrial facilities data; sector role based on engineering reference.

Local climate

Solvay Sodi Devnya Soda Ash Plant sits in a humid subtropical climate zone (Köppen Cfa), at 43.2°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 1385 W/m² to ambient — roughly 1.06× 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.
