Estimation of the environmental impact of MSWI bottom ash for reuse as a building material based on its composition

Abstract

A procedure for the determination of the total element composition of municipal solid waste incineration (MSWI) bottom ash (BA) based on borate fusion sample preparation followed by ICP–AES is developed as an alternative for a leaching test. Quantification limits for all the tested hazardous elements (Al, Ba, Cа, Co, Cr, Cu, Fe, Mg, Mn, Na, Ni, Pb, Si, Sr, Sb, Sn, Ti, V, Zn, Zr, S, P) are below the leaching ranges and total amounts for trace elements in MSWI BA, thus providing a quantitative assessment with low errors, including trace components. The total error of measurement is below 10% for most elements. Using ICP–AES and ion chromatography, good concordance of the data for trace elements and chloride and sulfate is shown. The comparison of the results from the standard leaching test with the data for untreated and washed MSWI BA samples shows good agreement for major, medium, and trace elements. The data on the dependence of the BA composition and a leaching capacity for various particle-size fractions of BA are compared. The advantages of the proposed approach are discussed.
