Michigan Sugar Company - Bay City — United States

Michigan Sugar Company - Bay City is a lime plant in United States. Its listed capacity is 151,730 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 #48 among 75 lime plants in United States. It emits about 187,146 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-38468900.

Measured and modelled emissions reconciliation

This facility is linked to GHGRP ID 1005758 for reporting year 2023. The official source reports 178,825 t CO2; Climate TRACE models 187,146 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 151,730 t of lime, Michigan Sugar Company - Bay City 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.

Local climate

Michigan Sugar Company - Bay City sits in a warm-summer humid continental climate zone (Köppen Dfb), at 43.6°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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with thermal cycling the leading environmental stress.

In this site’s local climate, a bare 150 °C surface sheds about 1419 W/m² to ambient — roughly 1.09× 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.
