Lhoist North America produces lime and lime-based products derived from calcium-rich limestone. The company's primary product, quicklime (or calcium oxide) is used for steelmaking, ore processing, industrial manufacturing, and construction. The company's products also serve environmental purposes such as wastewater treatment and softening drinking water, as well as roadbed stabilization. Lhoist North America provides lime slurry (hot liquid lime) to its customers from its mobile PORTA BATCH concentrated production units. One of the largest lime companies in the world, Belgium-based Lhoist, owns Lhoist North America, which was founded in 1966.
Lhoist North America's quarries and plants are primarily located in the southern and western US. However, products can be delivered anywhere in the US, Canada, or Mexico.
