Effect of mixing banana peels with frish cattle manure on biogas production [electronic resource]

Includes bibliographic reference

Egypt is an agricultural country and has a big potential of biogas generation from different types of wastes. Producing of biogas from agricultural wastes gives new and clean energy and good organic fertilizer as a method to protect environment from pollution by wastes. The digestion of banana peels mixed with cow dung for biogas production at laboratory scale was the subject of this investigation. Laboratory experiments were conducted to evaluate the biogas production from mixing banana peels fruits with fresh cattle manure in order to explore their potential application in biogas production. The study was carried out at a control temperature of 35±2°Cfor a period of 57 days with a total solid concentration of8% in each reactor. The biogas and methane produced were collected by water displacement method. In the current work, four reactors were used: A, B, C and D contains 0, 20, 40 and 60% banana peels (by weight) mixed with fresh cattle manure respectively. The experiments run out in anaerobic system under control of temperature. The results showed that mixing banana peels ratio of 40% increase biogas production but 'increasing the ratio to 60 % or more cause decreasing in biogas production
