Local Environmental Impacts
In addition to dust and noise, the emission of airborne pollutants is a major challenge in our cement business. While dust and noise are produced at many stages in the production process, airborne pollutants such as carbon monoxide, sulfuric oxide, heavy metals, dioxin, and furan are produced only during pyroprocessing. The emission of these pollutants is monitored on an ongoing basis, and we are committed to reducing airborne pollutants with new filtering technologies and innovative production processes. This mitigates the impact of our activities on the environment and human health.
In 2013 and 2014, we already introduced industry indicators for water reporting at all of our cement plants. Water consumption figures for our cement business line will be made available for the first time in the Sustainability Report 2015. We have also begun collecting such figures for aggregates and ready-mixed concrete plants. Results will be reported in the coming years. By 2030, individuall water management plans will be implemented at all plants located in regions suffering from water scarcity.
In the area of waste management, our primary emphasis is on mitigating the cement kiln dust that is produced during clinker production. This dust is removed from the kilns in order to prevent large dust deposits, which could lead to kiln failure. We utilize this dust as an alternative raw material during cement production, thus augmenting our ecological efficiency.
