bottom ash (Fig.1 b) were principality quartz (SiO2) and calcite (CaCO3).
The SEM images of fly ash and bottom ash are presented in Fig. 2. It can be seen that par-
ticles with various shapes and sizes. The pores distribution is quite heterogeneous. The particles
are amorphous structure are not well connected (Fig.2 a and c). From the images of b in Fig. 2, it
can be seen that there are needle-shaped particles. From the images of d, it can be seen that
there are needle-shaped particles. Elongated particles which have dense structure are seen as
well (Fig. 2 d).

Since MSWI bottom ash and fly ash contain contaminants within them, for production of
bricks from bottom ash and fly ash using whatever method, it is important to ensure that the
heavy metals within the original waste material are effectively and safely immobilized. Leaching
analyses can be conducted following 2003/33/EC [6], USEPA, ASTM and/or other standard
methods to check if the leached elements meet the related standard criteria.
According to normative reference [7] (LR AM įsakymas D1-805), slag may be used for civil
and building engineering purposes when the metal content in it is not more than 5%, organic
content – not more than 3% of its weight, heating loss – not more than 6% and leaching rate –
not more than the specific indicated values.

The application of municipal solid waste incineration fly ash in alumosilicate systems is
greatly relevant when it is necessary, at high temperatures, to bind and immobilise heavy metals
into insoluble compounds. At high temperatures, Pb and Zn metals are encapsulated in alumosil-
icate systems, thus leading to considerably low leaching values [8, 9]. In order to accelerate car-
bonation processes, before the use, fly ash may be additionally treated with water thus reducing
amounts of Pb, Zn, Cu elements [10]and chlorides [11]. It can be as well treated with water and
cleaned using electrolytic process [12].
Based on the experience of other countries, authors think that municipal solid waste (slag
and fly ash) may be effectively used for the production of alumosilicate products.
