Besides using raw materials sustainably, using resources responsibly is also part of sustainable waste management. We therefore fulfil the necessary permit requirements. We prevent wastewater and waste as best we can, while unavoidable waste is properly disposed of in line with statutory requirements.
Our policy, on which our waste hierarchy is based, is to prevent, reuse, recycle and eliminate. Preventing waste is the top priority. To do this, we examine our options for preventing waste in the relevant areas so that potential measures to reduce waste can be incorporated starting at the planning and procurement stage.
Comprehensive waste management ensures that all waste generated is disposed of properly in line with statutory requirements. A distinction is made between hazardous and non-hazardous waste as well as between recycling and eliminating waste in disposal. This is taken into account for further disposal. Disposal information systems are used to handle disposal services; these systems ensure that the applicable statutory and contractual conditions are adhered to in the disposal of generated waste.
Residual materials from our coal-fired power stations make up the majority of the waste generated. The ashes from the hard coal-fired power stations and gypsums produced during the flue gas desulphurisation of our coal-fired power stations are sold as power plant by-products. The ashes from the lignite-fired power plants are 100% eliminated in our landfill sites for residual materials from power plants. Further waste is also generated in our businesses, which is also handled by the waste management system. We handle residual materials and waste from our power plants, generated during their operation as well as in the process of dismantling power plants, in line with statutory requirements.
