TY - CONF A1 - Enzner, Verena A1 - Holm, Olaf A1 - Abis, Marco A1 - Kuchta, Kerstin T1 - The characterisation of the fine fraction of MSWI bottom ashes for the pollution and resource potential N2 - The fine fraction of bottom ash from municipal solid waste incineration is characterized of both a high pollution and relevant resource potential. Methods for studying the environmental behaviour of solid residues are leaching tests. Various leaching test are adopted all over Europe with liquid to solid ratio of 2 or 10 l/kg. In Germany three different leaching Tests are valid with the commencement of the draft of the ordinance of reuse of mineral waste as alternative building ordinance. Comparing two batch tests, only the concentration for chloride is comparable. To evaluate the metal resource potential in the sand fraction wet chemical Methods have been applied. Methodical problems were caused mainly by the material heterogeneity and especially for precious metals due to their low concentration around 1 mg/kg. Other Methods have been available, but hardly applicable. T2 - 16.
