Tailored flue gas treatment for every industrial challenge
Industrial processes generate flue gases that may contain acidic pollutants, heavy metals, and organic micro‑pollutants. At Lhoist, we help you control these emissions efficiently, so you can meet regulatory requirements, protect your equipment, and improve operational performance. With decades of experience, we support operators across all types of industries, including waste‑to‑energy, biomass, industrial boilers, steel and non-ferrous metals, cement, and more. Our high‑efficiency calcium‑based reagents, combined with our process expertise, help you achieve consistent environmental performance and reliable compliance.
