Biogas Potential of Some Selected Kitchen Wastes Within Kaduna Metropolis
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 5
Abstract
A comparative study of biogas potential of some selected kitchen wastes within Kaduna metropolis was carried out. The Volatile Solid, Total Solid, Moisture Content and Ash Content were examined. The materials used as feedstock were Food waste (yam peels, plantain peels, and potatoes peels) and fruit waste (orange and pineapple peels). Varying volumes of digesters were employed for biogas generation. The digestion process was carried out under ambient temperature for a retention period of 30 days. Anaerobic digestion is very sensitive to change in pH therefore pH was maintained at 6.7 - 6.9 for a healthy system. The result of the study showed that yam peel gave the highest value of 89.37ml/week of biogas and the lowest yield was observed with orange peel having 18.26ml/week of biogas. The mean values were within the range of 32.15ml - 92.43ml weekly for all the food wastes. While all the fruit wastes gave a mean value of 18.26ml – 36.20ml weekly. This showed that the type of waste had significant effect on the quantity of biogas produced thus, anaerobic digestion process a viable option for effective degradation of organic wastes
