Characterization of sewage sludge for sustainable urban environments: assessing heavy metal enrichment, thermal decomposition, and pyrolysis behavior/ Mohd Syazwan Mohd Ghazali and Syed Shatir A. Syed-Hassan

Rapid urbanisation and population growth have led to a surge in sewage sludge (SS) generation, posing environmental challenges due to its complex composition, particularly heavy metal content. This study investigates heavy metal analysis, thermal decomposition behaviour, and slow pyrolysis of SS to...
