The main environmental impacts of lime production are atmospheric pollution and energy use. The lime roasting process is the main source of emissions and a major energy consumer. The secondary processes of lime quenching and grinding can also be significant. Depending on the specifics of the production process, lime plants emit emissions to air, water and soil (as waste). Additionally, the environment is affected by noise and unpleasant odours. The main air pollutants are dust, nitrogen oxides, sulphur dioxide and carbon monoxide. The emissions of pollutants from individual industrial plants depend on the volume of production, the structure of the plant, the availability of gas cleaning equipment, technological features and other circumstances. The production of aerated concrete blocks does not emit any harmful substances. In order to reduce the harmful effects on the environment from the emission of dust in the production of aerated concrete blocks the following requirements must be met:
1) the filling of concrete ingredient storage tanks must not exceed the prescribed standards;
2) the use of sealed containers and packaging for the storage and transportation of raw materials.
Waste, entering the soil during the production of blocks of aerated concrete, is not formed, as waste and scrap products are crushed in a crushing plant and reused as aggregates, process water after treatment is used for recycling. All of this significantly reduces environmental pollution.
