Nature-based faecal sludge treatment involves solid-liquid separation followed by dewatering. These are energy-efficient, cost-effective, and support resource recovery, though their efficacy varies. Inadequate knowledge of characteristics from different technologies limits agricultural use. This study evaluates treated unplanted drying beds, planted co-composted sludge, focusing on characterization soil application potential. Non-parametric statistical analysis compared critical parameters. No significant differences were found in pH, bulk density, phosphorous, C:N ratio, secondary macronutrients. However, co-compost had higher conductivity (4.9 dS/m) potassium (1.09%) lower total nitrogen (2.15%) due to additional feedstock mineralization. PDB organic carbon (41%) as it's partially digested. Co-compost's balanced nutrient profile enhances fertility. Heavy metal concentrations for all treatments fall within quality guideline limits. findings confirm the potential a sustainable amendment highlight need standardized guidelines.
