Due to the rapid population growth and unmanageable urbanization, one of the burning issuesrnfaced by the world today is management of all types of wastes. This study has been conducted onrnthe production of biogas by anaerobic co-digestion of food wastes with goat manure. Food wastern(FW), goat manure (GM) and their mixtures were anaerobically digested for 40 working days. Thernproximate composition analysis of the FW and GM had shown that, whereas the GM was higherrnin TKN value (2.1%), the MFW was higher in C/N ratio (34.0). During this study FW and GMrnwere combined into five MFW to GM mixing ratios of 1:0, 1:1, 2:1, 1:2, and 0:1; and a total of 45rnMRs (nine for each mixing system) were prepared in 1-liter plastic bottles. The pH of these MRsrnwas adjusted to 6, 7, and 8 by adding 10 N NaOH. Three water baths were set to three temperaturernvalues of 30o C, 35o C and 40o C in which the 45 plastic bottles of 1-liter capacity (15 plasticrnbottles in each water bath) as main digesters were immersed. The experimental AD of this studyrntook 120 days (40 working days for each experimental setup) to produce biogas. The combinationrnsystems of the MFW and GM for co-digestion overcomes the imbalanced C/N ratio of the MFW.rnThe efficiency of the mono-digestion of MFW only, GM only and co-digestion of the MFW withrnGM were studied and compared. Statistical design of the experiments and data analysis wasrninvestigated using the general factorial design. Statistical test had shown that the model "F values"rnfor both the responses, the biogas volume and methane content in the biogas were statisticallyrnsignificant (P
