Abstract

Incineration of municipal solid waste (MSW) is relatively new in India. The process results in generation of residues, bottom ash (BA) and fly ash which are presently dumped back in landfills. The study investigated the properties of MSW incineration (MSWI) BA from two MSW waste-to-energy (WtE) plants in Delhi and the results have been compared with coal bottom ash (CBA) from a local thermal power plant and two local soils, namely: Delhi silt and Yamuna sand. MSWI BA with particle size predominantly in the sand size range was found to be coarser to CBA and local soils making it suitable for earthworks. The chemical composition revealed that SiO2 in the form of quartz is the major constituent of MSWI BA. The organic content was more than regulatory levels for earthworks. Dissolved solids, chlorides and sulfates were very high in comparison to CBA and local soils. The above findings indicate that MSWI BA can possibly be reused in embankments or filling of low-lying areas, provided some environmental control measures are adopted at site or pre-treatment is undertaken to attenuate the leaching of salts and reduce organic content.
