O-N Minerals Chemstone Company — United States
Lime Plant in United States. Approximate location 39.25669, -78.0848.
Lime PlantUnited StatesCO₂ estimate (modelled)
O-N Minerals Chemstone Company is a lime plant in United States. Its listed capacity is 145,708 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 #50 among 75 lime plants in United States. It emits about 179,543 t CO₂e a year from Climate TRACE. That is 0.03% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas. Its CO₂ per unit of capacity is 87% above the national median for this sector.
Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-38468905.

In context: how this facility compares
At 145,708 t of lime, O-N Minerals Chemstone Company is below the median lime plant in United States (208,805 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.

Carbon cost and Scope 1 emissions
At its reported 180k t CO₂e/yr (Scope 1), O-N Minerals Chemstone Company carries no domestic carbon price, and its products are not CBAM-covered goods, so there is no border-carbon liability. At the EU ETS reference price (€75/t) the emissions carry an indicative carbon value of €13.5M/yr.
Measured CO₂: 143k t/yr — verified GHGRP (reporting year 2023) (21% below the modelled estimate). Modelled estimate 180k t/yr (Climate TRACE), high-confidence match, cross-checked via the measured-vs-modelled dataset (n=711).
Carbon price: EU CBAM €75/t · EU ETS €85/t, September 10, 2026, refreshed live via Carbon Hub. CO₂: measured (GHGRP RY2023), cross-checked vs Climate TRACE. Indicative carbon value, not the cash bill — free allocation applies; not compliance advice.

Local climate
O-N Minerals Chemstone Company sits in a humid subtropical climate zone (Köppen Cfa), at 39.3°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 1384 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.
