Environment
Among lime application areas, environmental protection is the one that has
experienced the greatest growth during recent years.
In this field Calcium Oxide and Hydroxide are used for the treatment of waste waters by controlling the pH, retaining heavy metals by precipitation, or for its flocculant capacity.

Lime also stabilizes the heavy metals present in certain industrial
residues and makes these residues more manageable.
In flue-gases treatment, Calcium Hydroxide is used a as dry powder or as milk of lime to neutralize the emissions of sulphur dioxide, hydrochloric acid, or dioxins, thus avoiding the emission of these pollutants into the atmosphere.
