Abstract: This study assessed the anaerobic co-digestion of layer and grill droppings (30:70) for methane output and microbial stabilisation efficiency.Comparing microbial load decrease, evaluating procedure effectiveness in stabilising particular infections, and estimating methane yield were the objectives of the study.pH, temperature, electrical conductivity, salinity, total dissolved solids, and gas generation were all measured daily for 30 days.Analysis of the data showed that both the total coliform count (1.20±0.20 to 0.00±0.00)and the total viable count (1.32±0.02 to 0.85±0.03)significantly decreased after digestion.Following digestion, the initially elevated levels of Shigella, Salmonella, E. coli, and Klebsiella were lowered to undetectable levels.After the initial acidity, the pH stabilised at about neutral (6.28).Temperatures varied between 21.0°C and 34.5°C, which is the mesophilic range.When measured in dm³, gas production followed a typical pattern of anaerobic digestion: low starting volumes (0.00481-0.00641dm³), a steady increase that peaked at 0.05911 dm³, and a fall (0.05078-0.02419dm³) as organic matter depleted.According to the study's findings, anaerobic co-digestion produced a significant amount of methane-up to 0.05911 dm3-significantly decreased microbial loads, and efficiently removed targeted pathogens.These results point to the possibility of using anaerobic digestion to produce energy from chicken droppings.
