“…In incineration, for example, the highest percentage of ash corresponds to bottom ash (15-35% by mass of treated waste) (ALLEGRINI et al, 2014;UNEP, 2017). Although the percentage of the mineral fraction (inorganic material) is lower than the carbonaceous matrix of a fuel, it constitutes an important role in the design and operation of energy recovery plants, as the ash can cause corrosion and fouling problems, as well as negatively influence the fuel potential (GRAMMELIS, 2011).…”

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.

“…The management of this ash varies from country to country, though landfilling, the recovery of valuable metals, treatment and its utilisation as a construction material are among the possible options (Crillesen and Skaarup, 2006). However, increasing pressure on natural resources and concerns about possible losses of valuable resources in waste management have led to growing attention on waste flows such as MSWI BA, which bears potential from a resource perspective (Allegrini et al, 2014;Morf et al, 2013). Scrap metals can be recovered from BA, thereby avoiding mining and the production of primary metals, while the mineral fraction can be utilised within the construction industry, substituting natural aggregates and other natural materials.…”

“…Scrap metals can be recovered from BA, thereby avoiding mining and the production of primary metals, while the mineral fraction can be utilised within the construction industry, substituting natural aggregates and other natural materials. Ferrous (Fe) and non-ferrous (NFe) scrap metals are found in MSWI BA in different grain size fractions (Allegrini et al, 2014;Hu and Rem, 2009;Hu et al, 2011b) and quality ; in fact, scrap metals can be affected by loss of quality (e.g. due to oxidation, corrosion processes), which varies from metal to metal and between different grain sizes of the same metal type.…”
