Sažetak
Management of waste materials for sustainable development imply their recycling and reuse. In this work the foam glass (FG) was prepared from powder mixture of waste materials: sewage sludge ash (SSA), recycled bottle glass culet, and carbonate foaming agent through one-step thermal process at temperatures up to 850°C. Prepared FG, with wollastonite as a major mineral phase, had open and connected pores from several mm to closed small pores ˂1mm and can be classified as macro- or meso-porous materials. FG fulfil requirements for masonry mortars. Low leaching of heavy metals confirmed its safely incorporation inside glass matrix. FG exhibited the antibacterial activity against emerging pathogenic bacterium Acinetobacter baumannii due to the alkaline reaction of FG in water medium. SSA and bottle glass could be successfully transformed by simple production method to FG as environmental friendly material.
