Method & Evidence

AimTo evaluate the compatibility of textile wastewater sludge (TWS) and cattle manure (CM) when blended into fuel pellets and assess their combustion properties for direct energy applications.
MethodExperimental analysis and material characterization.
ProcedureTextile wastewater sludge and cattle manure were dried, ground, and blended in various ratios (75:25, 50:50, 25:75 CM/TWS). These blends, along with non-blended samples, were pelletized. Proximate analysis (moisture, fixed carbon, volatiles, ash), ultimate analysis (CHNO), gross calorific value (GCV), bulk density, and metal content in the ash residue were determined for all samples.
ContextWaste valorization and renewable energy production.
