Produktion und Verwendung von Nebenprodukten aus Kohlekraftwerken

Coal combustion products are produced during the generation of electricity in coal fired power plants. In the last years about 25 million tonnes per year were produced and utilised in Germany. CCPs like boiler slag, bottom ash, fly ash or FGD gypsum were used since many years as quality controlled raw material or building material in the construction industry or in civil engineering as well as for restoration and reclamation purposes in open cast mines. The power plant operators spent much effort in producing a quality material which can easily be utilized. This leads to high utilization rates of about 98 to 100 percent. This article gives an overview about the results of the VGB survey "Production and utilisation of CCPs in Germany" of the years 1997 to 2007.
