Ray Nkonyeni Cement Plant — South Africa
Cement Plant in South Africa. Approximate location -30.67523, 30.34639.
Cement PlantSouth AfricaCO₂ estimate (modelled)
Ray Nkonyeni Cement Plant is a cement plant in South Africa. Its listed capacity is 1,480,000 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 Natal Portland Cement Company Pty Ltd. By capacity it ranks #3 among 8 cement plants in South Africa. It emits about 630,424 t CO₂e a year from Climate TRACE. That is 3.4% of the CO₂e from the 24 facilities in South Africa that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 18% above the national median for this sector.

In context: how this facility compares
At 1,480,000 t of cement, Ray Nkonyeni Cement Plant is around the median cement plant in South Africa (1,300,000 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.

Carbon cost and Scope 1 emissions
At its reported 630k t CO₂e/yr (Scope 1), Ray Nkonyeni Cement Plant carries no domestic carbon price — and as a CBAM-covered product, its 630k t at the EU CBAM rate (€75/t) is €47.5M/yr of exposure on EU-bound exports. CBAM share rises from 2.5% (2026) to 100% by 2034. No domestic carbon price — but cement, steel, aluminium, fertilizer and hydrogen exported to the EU face CBAM at €75/t (rising to 100% by 2034).

Local climate
Ray Nkonyeni Cement Plant sits in a humid subtropical climate zone (Köppen Cfa), at 30.7°S in the southern hemisphere.
Köppen zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.
In this site’s local climate, a bare 150 °C surface sheds about 1292 W/m² to ambient — roughly 0.99× 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.
