National Matozinhos Cement Plant — Brazil

National Matozinhos Cement Plant is a cement plant in Brazil. Its listed capacity is 1,060,000 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 Companhia Nacional de Cimento - CNC Ltda. By capacity it ranks #18 among 31 cement plants in Brazil. It emits about 470,349 t CO₂e a year from Climate TRACE. That is 0.34% of the CO₂e from the 130 facilities in Brazil that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 23% above the national median for this sector.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-32437276.

In context: how this facility compares

At 1,060,000 t of cement, National Matozinhos Cement Plant is around the median cement plant in Brazil (1,080,000 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

National Matozinhos Cement Plant sits in a humid subtropical (dry winter) climate zone (Köppen Cwa), at 19.5°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 a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1288 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.
