Retznei Cement Plant — Austria

Retznei Cement Plant is a cement plant in Austria. Its listed capacity is 625,000 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 Holcim (Österreich) GmbH. It emits about 348,955 t CO₂e a year from Climate TRACE. That is 2.0% of the CO₂e from the 15 facilities in Austria that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 54% above the national median for this sector.

Measured and modelled emissions reconciliation

This facility is linked to EUTL ID AT_61 for reporting year 2023. The official source reports 262,865 t CO2; Climate TRACE models 348,955 t CO2e.

Limits of this comparison

• Measured CO2 and modelled CO2e are not identical accounting constructs.
• The crosswalk is an entity match, not proof that reporting boundaries are identical.
• The reporting year is shown explicitly and values are not extrapolated to the current year.

In context: how this facility compares

At 625,000 t of cement, Retznei Cement Plant is around the median cement plant in Austria (625,000 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

Retznei Cement Plant sits in a temperate oceanic climate zone (Köppen Cfb), at 46.7°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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1406 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.
