Russian steel maker NLMK has introduced a new online air quality monitoring system at the sites of Novolipetsk Iron and Steel Works and Stoilensky GOK. The equipment will allow you to collect data for a more detailed and reliable analysis of the company's impact on the environment. The complex consists of mini-posts with special sensors, which are located on the border of the sanitary protection zone of enterprises. Sensors measure the concentration of controlled substances and every five minutes transmit readings to a single system where environmentalists can monitor the state of the environment and respond to deviations.The complex also takes into account the parameters of weather conditions, which allows, if necessary, to adjust production processes. 12 complexes are installed at two sites.By the end of the year, the company plans to introduce a similar system at the site of the Altai-Koks plant.
