Municipal solid wastes incineration (MSWI) is an important part of the waste management systems in many European countries. Incineration process generates two main by-products: fly ash (FA) and bottom ash (BA). Bottom ash is composed of a variety of oxides, heavy metals and salts. Landfilling of untreated (fresh) BA can cause soil, surface and ground water contamination problems, because atmospheric precipitation in BA formed leachate, which contains of various materials. In this study investigates the influence of natural weathering to heavy metals leaching from BA. Leaching tests of bottom ash were carried out in 6 months, leachate samples were taken at 12 times (every 2 weeks). Heavy metals (Pb, Cu) concentrations were determined by atomic adsorption of spectral analysis method. The research shown, that the highest lead and copper concentration was determinated in 2 weeks weathered bottom ash leachate, respectively was 0.613 mg l–1 and 0.068 mg l–1. In both cases the concentration of Pb (0.010–0.052 mg l–1) and Cu (0.010-0.018 mg l–1) became almost stable after 12 weeks. Can be concluded, that short-term (3 months) natural weathering is sufficient time for stabilise MSWI bottom ash and heavy metals (Cu and Pb) leaching. After 18–24 weeks heavy metals concentrations stabilized and remained almost constant.

Energetic and metallurgic wastes are widely used as Supplementary Cementitious Materials (SCM) and aggregates in order to reduce the concrete price and/or enhance its durability and mechanical properties. Ashes generated in process of Municipal Solid Waste Incineration (MSWI) feature certain similarity with conventional SCMs and thus there is a potential to utilize MSWI ashes as concrete admixtures. Unfortunately high variety of MSWI ashes is observed as consequence of differences in incinerated waste composition and also variability of applied combustion and air pollution control technology. Therefore it is necessary to evaluate the applicability of MSWI ashes individually. The present paper deals with influence of MSWI bottom ash from a Czech incineration facility on strength and Young’s modulus of cementitious mortars where the MSWI bottom ash was used as aggregates. Even though the content of ash was as high as 40 % of aggregates dosage the influence on mechanical properties was found to be not very significant. The strength was not lost by MSWI admixing, the Young’s modulus decreased somewhat.

Mswi Bottom Ash

The rapid development of industrialization, urbanization, and population of the society augments the rising amount of municipal solid waste (MSW). With the advantage of considerably reducing mass and volume of solid wastes and generating energy, the incineration is a widely used treatment method for MSW. During the incineration process, the organic substances contained in the wastes are combusted, and the massive residues are remained. Of the incineration residues, bottom ash takes up to 80–90%, and the remainders are fly ash along with air pollution control residues. Dealing with the municipal solid waste incineration (MSWI) bottom ash in a sustainable manner is the primary principle. Significantly, MSWI bottom ash has been successfully utilized in diverse beneficial applications in recent decades, especially in civil engineering applications. This paper investigates the mechanical properties and validity of MSWI bottom ash as applicable substitutes of conventional subgrade materials. For this reason, a series of direct shear and CBR tests are performed on specimens with different water contents and dry densities.
