Ozinga opens cement mill in East Chicago: what it means for regional concrete and carbon

Ozinga has opened a cement mill in East Chicago, Indiana, adding local milling capacity for its ready-mix concrete operations. The facility shortens the supply chain for customers in the Chicago area and brings some industrial capacity back to the region. Cement is one of the hardest materials to decarbonize because most of its CO2 comes from the chemical process that turns limestone into clinker, not just from the fuel used to heat the kiln. A new mill can cut transport emissions and improve supply reliability, but the bigger carbon story depends on where the clinker comes from and what fuel or alternative materials the operation uses. The article covers the opening and the company's plans in the region. Anyone tracking industrial decarbonization should read it for the details on capacity, clinker sourcing, and any efficiency measures tied to the project.
