Bottom ash (BA) from waste-to-energy (WtE) plants contains valuable components, especially Fe and NFe metals, which can be recovered. Metal-free mineral fraction can be used in construction industry. To assess the resource recovery potential of BA, it was necessary to obtain the information about its material composition. We analyzed in total six samples from all three WtE plants in the Czech Republic. It was found that raw BA contains 10–23 % of glass, 2–5 % of ceramics, 10–16 % of magnetic fraction, 6–11 % of ferrous scrap, and around 1.3–2.8 % of non-ferrous metals (NFe). The contents of individual components were also studied with respect to the granulometry. Paper will summarize all the results and will outline bottom ash potential as well as economic aspects of bottom ash treatment and material recovery.
