DIRECTORY OF LIME PLANTS AND HYDRATING PLANTS IN THE UNITED STATES IN 2022

At yearend 2022, 73 lime plants were operating in the United States, including 1 plant in Puerto Rico. In addition, there were 46 hydrating plants, which included 30 co-located with lime plants and 16 stand-alone hydrating plants (including 2 facilities where the lime kilns were idle).

Table 1 (p. 2–9) lists lime companies, lime plants, and hydrating plants in the United States, organized by State or Territory, and identifies the type of lime produced at each plant. Table 2 (p. 10–12) lists lime companies in alphabetical order, provides information on the type of kilns used at each plant, and indicates whether the plant mines or purchases its kiln feed. Figure 1 (following table 2) is a map that shows the general location of each plant (excluding stand-alone hydrating plants) and identifies whether it is captive—a plant that produces lime entirely for internal consumption—or commercial.

In the context of this directory, a lime plant implies that it is operating a kiln or kilns and is producing quicklime.
