Summary, etc This study sought to evaluate the treatment performance efficiency of Black Soldier Fly process on the fecal waste via SCBS-UDDT model. In SCBS-UDDT model, the feces container was seeded with actively feeding BSF larvae before being introduced for fecal sludge (FS) collection, allowing for FS conversion on-site. The experiment investigated on-site and offsite treatment of UDDT-CBS generated feces using the BSF larvae by installing six UDDT-CBS systems within six households at Nchiru where for onsite treatment 3 was pre-seeded with 5-day-old BSF larvae which fed on the fecal matter in the containers and were left at the site for 14 days. For offsite treatment 3 UDDT-CBS were installed in households where, the used containers were collected and swapped with clean ones daily and fed to 5-day-old larvae in batch feeding as a control experiment. Samples were taken at three-day intervals for analysis of; i) growth performance, ii) Protein, fats, and carbohydrates as nutritional components of the Black Soldier Fly (Hermetia illucens) larvae during and after fecal sludge treatment, and, iii) Escherichia coli inactivation efficiency. SPSS version 25 software was used to analyse the data, which was then presented using tables, frequency distribution curves, and figures. From the findings, Total suspended solids varied between 24.6±1.5 and 22.4±1.5 for seeded treatments while non-seed treatments recorded a relatively higher mean range between 30.5±1.8 and 32.1±2.1) where a significant variation occurred between the two treatments at p<0.05. Volatile suspended solids (%) varied between 20.6±1.4 and 22.7±1.4 for seeded treatments; while non-seed treatments recorded a relatively higher mean range between 28.5±1.6 and 29.5±1.9, a significant variation occurred between the two treatments at p<0.05. Moisture content varied between 67.9±1.8 and 77.6±1.5 for both seeded and non-seeded treatments which varied significantly (SH and NH) at p<0.05. Crude protein content varied significantly between the two treatments (SH and NH) at p<0.05 which ranged between 38.6±1.7 and 39.9±2.3 for seeded and 35.5±1.0 and 36.0±0.4 for non-seeded treatments. Carbohydrates mg/ml content varied significantly between the two treatments (SH and NH) at p<0.05 which ranged between 1.2±0.4 and 1.3±0.5 for seeded and 0.8±0.0 and 0.88±0.00 for non-seeded treatments, with seeded treatments recording a relatively higher reading. Fat concentration (%) varied between 20.2±3.0. and 21.0±3.5 for seeded and 18.4±0.9 and 19.0±0.7 for non-seeded treatments recording a significant variation (SH and NH) at p<0.05. E. coli log (CFU/ml) mean varied between 7.3±1.3 and 10.1±2.8 for seeded treatments while non-seed treatments ranged between 7.5±1.6 and 10.4±3.2. A significant variation occurred between the two treatments at p<0.05(SH and NH). Larval weight gain (g/30BSF larvae) varied significantly between the two treatments (SH and NH) at p<0.05. In seeded households, the waste reduction efficiency recorded was 67.74% the highest, and in non-seed systems, it was 66.68%. At 53°C which was the highest temperature E. coli colony forming units were reduced to 2.94log for the seeded system and 3.5log for non-seeded system. These results indicated the potential of utilizing BSFL by seeding in UDDT-CBS embracing nutrient recovery. Recommendation for follow up with community for uptake of results.
