| dc.description.abstract | Background: Globally, livestock production is one of the major causes of some of the world's most pressing environmental problems, global warning, lang degradation, air water pollution, and loss of biodiversity. It has been estimated that livestock are responsible for 18 percent pf green house gas emissions. However, the livestock sector's potential contribution to solving environmental problems is equally large, and major improvements could be achieved at reasonable cost (Kanto, 2011). The use of biogas as effective farm equipment as an excellent example of sound integrated crop and livestock management (Largo, 2012). Methods: The eight 200-l drums of plastic Drum Biogas Digester (PDBD) with open botton and gas fittings above a closed lid were immersed in an open pit slurry septic tank. Biogas collection related parameters namely: full biogas capacity drum duration, volume of captured biogas, flow rate, gas deplection time and biogas production economic efficiency were gathered. Results: The volume of biogas produced after 96 hours (4 days) was 8,856.72 l which when allowed to a continuous delpetion or emptying the submersion of the PDBD, the recorded time consumed was 16.5 minutes through a double burber stove with maximum level of fire. Conclusion: The PDBD was proven economically efficient and effective as it generated a ROI of 86.75% which indicated that for every peso of investment, the return is equivalent to PhP 0.8675, and a MBCR of 0.13 which indicated that for every additional peso of variable costs of the PDBD, the gross return was PhP 0.13. This study will encourage and help livestock farmers in managing their farm wastes at the same time producing a sunstantial savings for not using the Liquefied Petroleum Gas (LPG). Besides, a PDBD will help in addressing the issues on climate change particularly in global warming. | |
