“…When comparing the RDF with the evaluated combustible fractions, it is assumed that Al2O3 composes a percentage similar to the paper/cardboard/Tetra Pak® fraction, and this similarity is given because Tetra Pak® packages have a high aluminum content in their composition, and this fraction is the most abundant in the RDF gravimetric composition (TIBURCIO et al, 2016).…”

The disposal of municipal solid waste (MSW) to thermochemical treatments promotes the formation of ashes as a by-product, which constitutes an important role in the design and operation of energy recovery plants, as the ash can cause corrosion and fouling problems. In this sense, this work analyzed samples of bottom ashes from combustible fractions (organic matter, plastics, textiles, paper/cardboard/Tetra Pak® and sanitary waste) of MSW in natura from Santo André – SP, Brazil. For this, a new methodology for sample preparation was proposed to evaluate the elemental composition of the bottom ashes, for later analysis by Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS). The obtained data showed a standard deviation of less than 10%, guaranteeing a greater reliability of the results and corroborating with standard deviations presented in the scientific literature. In addition, the elemental composition of the bottom ash was similar between the different combustible fractions evaluated. Keywords: MSW, Combustible fractions, SEM-EDS.

Procese susidaro du pagrindiniai atliekų srautai: pavojingi -lakieji pelenai (angl. fly ash) ir nepavojingidugno pelenai ir šlakas (angl. bottom ash). Dugno pelenais ir šlaku yra įvardijamos degimo kameroje degimo proceso pabaigoje iškrentančios deginimo proceso atliekos bei nedeganti liekana, susikaupusi degimo kameros dugne. Pelenus ir šlaką taip pat gali sudaryti per grotelių kiaurymes iškrentančios dalelės bei nepavojingosios garo katilo dulkės. Dugno pelenai sudaro 85 % proceso liekanų masės (vidutiniškai 16-35 % pradinės kuro masės) (Rambaldi et al. 2010;Yang et al. 2012;Schabbach et al. 2012;Wei et al. 2011). MOKSLAS -LIETUVOS ATEITIS SCIENCE -FUTURE OF LITHUANIADeginant atliekas gauti dugno pelenai ir šlakas yra daugiakomponentė sistema, kurią sudaro išsilydžiusių produktų ir nesudegusių dalelių mišinys, taip pat medžia-gos, kurios deginimo procese išliko beveik nepakitusios (geležis, spalvotieji ir sunkieji metalai, stiklas, keramikos nuolaužos ir mažos statybinių atliekų dalelės) .Dugno pelenų ir šlako savybės labiausiai priklauso nuo deginamų atliekų srauto sudėties.

“…As concerns the concrete production, the use of bottom ash as concrete aggregate could affect the durability of concrete because of the metallic aluminium and glass particles which may contributes to cracks and alkali-silica reaction, respectively [17][18][19]. In addition, the high content of chloride in the bottom ash can contribute to steel corrosion in the case of armoured concrete [20].…”

The aim of this work was to evaluate the use of solid residues derived from municipal solid waste-derived solid recovered fuel incinerated in a circulating fluidized-bed boiler for concrete production. The concrete mixtures casted by partially replacing the natural aggregates with bottom ash (27 %) and exhausted sand (13 %), according to the European standards for concrete, may be classified in the C16/20 class. The leaching tests performed on monolithic concrete samples showed that the concentrations measured in the leachates were lower than limit values for waste recovery, with the only exception of nickel for the mixture made with the exhausted sand
