ABSTRACT
Characterization of municipal solid waste (MSW) is a critical precursor to designing effective energy recovery systems. This manuscript presents comprehensive proximate and ultimate analyses of MSW streams from three urban locations, highlighting variations in moisture, volatile matter, fixed carbon, ash content, calorific value, and elemental composition. Case studies from Pune (India), Portland (USA), and Milan (Italy) illustrate the influence of source separation and seasonal variability on MSW quality. The methodology encompasses standardized sampling protocols, ASTM- and ISO-compliant laboratory tests, and statistical treatment of results. Key findings reveal calorific values ranging from 8.5 to 12.3 MJ/kg and ash contents between 10% and 28% on a dry basis, indicating substantial potential for combustion and gasification. Conclusions emphasize the necessity of local MSW characterization for selecting suitable conversion technologies and optimizing operational parameters. Ten references up to 2014 support the engineering-discipline focus of this study.
