Abstract: About 50% of Municipal Solid Waste is incinerated (MSWI) in Europe what represent ca. 50 Mt/a of MSWI bottom ash (BA). Bottom ash contains several marketable components (iron scrap, non-ferrous metals, glass) which can by separated from the main BA stream and placed on the market with secondary sources. The resting material is, by its composition and properties, similar to natural aggregates and can be used in this way. The influence of metals separation form BA on its behaviour in concrete was tested by using BA from Praha Malešice Waste-to-Energy Plant. Particle size fractions 4/8 and 8/16 mm of this BA can be used as aggregates in concrete up to 50 vol. % of given fraction without any significant loss of concrete strength. The combination of valuable component separation form BA and recycling of the rest portion as aggregates feature promising way of BA management reducing the amount of BA to be landfilled to minimum.
