Krausová, Aneta ; Šyc, Michal ; Kameníková, Petra ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Struska ze spalování komunálních odpadu obsahuje radu materiálu, které mohou být dále využity jako druhotné suroviny, zejména železné a neželezné kovy, nekteré vzácné kovy a kovy vzácných zemin nebo napríklad sklo. Minerální frakce je po vytežení cenných surovin, vhodnou náhradou prírodních materiálu ve stavebním prumyslu. Významným benefitem, pri zpracování strusky, je pro provozovatele spaloven také redukce poplatku za skládkování. Řada spaloven v Evropě je vybavena separačními linkami pro získávání železných a neželezných kovu. V České republice je linka pro získávání neželezných kovů instalována na spalovne SAKO Brno, ostatní dvě spalovny separují pouze snadno dostupný objemný železný šrot. Pro posouzení využitelnosti a při rozhodovávání o aplikaci vhodné technologie pro úpravu strusky je nezbytná znalost jejích fyzikálních vlastností a materiálového složení, které je značně variabilní a závislé na složení spalovaného odpadu. Analýzou strusky z českých spaloven bylo stanoveno materiálové složení.

Characterization of MSWI Bottom Ash and Assessment of Resource Recovery Potential
Šyc, Michal ; Kameníková, Petra ; Krausová, Aneta ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Bottom ash from municipal solid waste incineration contains valuable components that can be recycled as secondary materials, such as ferrous and non-ferrous metals, rare earth elements, glass etc. Metal-free mineral fraction is reusable in construction industry. The composition of bottom ash is highly dependent on the composition of incinerated waste but in average can be around 5–13 % ferrous metals, 2–5 % non-ferrous metals, 15–30 % glass and ceramics, 1–5 % unburned organics and 50–70 % mineral fraction. Several incineration plants in Europe are equipped with advanced systems for metals recovery, mostly based on magnetic separation of ferrous metals and separation of non-ferrous metals usually by eddy-current separators. To study the possibilities of bottom ash treatment in the Czech Republic it is necessary to obtain data about the bottom ash composition and evaluate the potential of resource recovery.

Recovery Potential of Bottom Ash from Municipal Solid Waste Incineration
Kameníková, Petra ; Šyc, Michal ; Krausová, A. ; Pohořelý, Michael ; Zach, Boleslav ; Svoboda, Karel ; Punčochář, Miroslav
This paper will present the composition of bottom ash determined in samples obtained from MSWI plant in Prague. The samples were first screened into fractions of grain sizes 0–2 mm, 2–4 mm, 4–6 mm, 6–8 mm, 8–10 mm, 10–15 mm, 15–20 mm and >20 mm. Each fraction, with the exception of fines bellow 2 mm, is manually sorted into glass, ceramics, magnetic particles, non-ferrous metals, unburned organics and the residual mineral fraction. It was found that the bottom ash contains in average 15–20 % of glass, 2–4 % of ceramics, 15–20 % of magnetic metals and around 2 % of non-ferrous metals. These results show that the bottom ash from in the Czech Republic is not significantly different from other European countries and has the potential for material recovery.

Fuel-energy Properties of Stabilized Sewage Sludge
Pohořelý, Michael ; Durda, Tomáš ; Moško, Jaroslav ; Šyc, Michal ; Kameníková, Petra ; Zach, Boleslav ; Svoboda, Karel ; Hartman, Miloslav ; Beňo, Z. ; Parschová, H. ; Houdková, L. ; Punčochář, Miroslav
The paper summarizes significant fuel-energy and physico-chemical properties of stabilized sewage sludge. Sewage sludge as a fuel is characterized by high proportions of water content, volatile matter content, ash content and a considerable amount of reactive, organic nitrogen (2-5 wt. % of dry matter). In addition to oxygen; silicon, phosphorus, aluminum, iron and calcium are the most abundant elements in the ash from the sludge. The lower calorific value of dry, anaerobically stabilized sewage sludge is 9-12 MJ kg-1 and it corresponds to a low calorific value of lower-class subbituminous coal or lignite.

Phosphorus Recovery from Sewage Sludge Ash
Šyc, Michal ; Kameníková, Petra ; Kruml, Matěj ; Sobek, Jiří ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Sewage sludge from wastewater treatment contains significant amount of phosphorus. Phosphorus recovery from secondary sources is nowadays increasing in its significance due to high consumption and rising price. The paper presents suitable methods for phosphorus recovery from wastewater, sewage sludge and sewage sludge ash. The preliminary results of lab-scale experiments on sewage sludge ash microwave enhanced thermochemical treatment are presented as well.

Šyc, Michal ; Kameníková, Petra ; Krausová, A. ; Baloch, T. ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Municipal solid waste incineration bottom ash contains wide range of valuable components, like ferrous and non-ferrous metals, rare earth elements, glass, ceramics and minerals for construction industry. The composition of bottom ash corresponds to incinerated waste composition and it is variable with respect to plant locality and season. The paper summarizes suitable methods for recovery of valuable components and presents the composition of bottom ash from ZEVO Malešice.
