Abstract
There has been a continuous increase in the use of wastes as secondary mate rials in the German cement industry. In principle there are two options: en e,gy utilization of the waste (as secondary fuel) or material utilization ( ns a raw meal component in the production of clinker and as an interground addition in cement). Which of the two utilization options has priority has to De decided from case to case in accordance with the directives of the Kr W-/AbfG (Recycling and Wastes Act). This article discusses the relevant pas sages of the text of the Act and illustrates their practical application wi th the aid of examples. The problems of toxic potential of wastes during ut ilization in the cement production process is also examined, particularly w ith regard to the 17th BImSch V (Ordinance of the Federal Environmental Imp act Act), TA Luft 86 (German Clean Air Standards), and the Prohibited Chemi cals Ordinance.
