<ns4:p><ns4:bold>Background</ns4:bold>: Transformative sanitation technologies aim to treat fecal sludge (FS) by thermal processes and recover resources from it. There is a paucity of data describing the relevant properties FS as viable feedstock for treatment in major geographical target areas, such India.</ns4:p><ns4:p> <ns4:bold>Methods</ns4:bold>: This study characterized collected septic tanks two cities located Indian southern state Tamil Nadu. samples were obtained at point discharge trucks Tiruppur (n=85 samples) Coimbatore (n=50 samples). Additionally, biosolids sewage plants (STP) Madurai characterized. Proximate ultimate analysis conducted fuel industry was carried out.</ns4:p><ns4:p> <ns4:bold>Results: </ns4:bold>The average higher heating value (HHV) across all (13.4 MJ/kg) much than (5.4 MJ/kg), which partially attributed high ash content 69% latter samples. The HHV ranged between 10 12.2 MJ/Kg. total solids (TS) 3.3% 2.0% respectively, while median TS 2.3% 1.2%. heavy metal found be below thresholds land disposal.</ns4:p><ns4:p> <ns4:bold>Conclusions: </ns4:bold>This one first studies that has systematically India determined its calorific content. We expect these serve input design treatment.</ns4:p>
