The natural raw material – lime – has accompanied humanity for millennia. The fossil raw material is widely used, whether as fertilizer, building material or dry mortar, and in fired or unfired form. Today, there is scarcely an industry in which lime or lime products are not used: Agriculture, forestry and environmental protection rely on high-quality lime products. Iron and steel refining, glass production, building material production, road construction, and air and water pollution control are just a few other applications for lime products. In agriculture and forestry lime is used as a fertilizer, and as animal feed in livestock farming, lime is indispensable.
