Limestone is a versatile raw material. It purifies, neutralises, fills and stabilises, which makes it an important ingredient for e.g. the paper, steel and construction materials industries as well as for environmental care and agriculture.
The paper industry uses limestone-based products as fillers and coating pigments. In the manufacturing of steel lime is required to remove impurities at different stages of the production process.
One of the oldest uses of limestone products is as a construction material. Limestone-based products are needed in road building, too. Quicklime and slaked lime are used for stabilising the soil, and limestone powder is used as a filler in asphalt.
In agriculture, liming reduces the acidity of the fields. Lime is also used to neutralise the acidity of watercourses and forests. Limestone-based products clean the flue gases from coal-fired power plants and are also used to regulate the acidity of drinking water and clean the waste water.
