| dc.description.abstract | Plastic drum biogas digester is now a fast becoming popular alternative source of non-fossil fuel based renewable energy. Aside from being a low cost and practical method for methane capture, for an 8,200 l plastic drum, it can be assembled and installed in 6 hours and biogas production can resume 9 hours after installation from an open pit and odorless and flies free slurry/septic tank. The study aimed to compare biogas production during night and day collection. The PDBD with open bottom night and gas fitting above a closed lid was immersed in front of an effluent drainage leading to a poultry slurry lagoon with a volume of 350.75 m3. Biogas related parameters namely: full capacity drum duration, colume of biogas capture, flow rate, depletion time and economic efficiency were gathered. The volume of biogas produced after 96 hours (4 days) was 2,580.64 l or 1316.65 kg which when allowed to uninterruptedly deplete through a single burner stove lasted for 4 hours and was equivalent to a flow rate of 10.98 l/minute. Total cost of PDBD is Php. 15,086.50. The savings derived in the use of biogas instead of LPG was Php27.42/l; ROI of 468.72%, Payback Period of 0.21 yr, and Marginal Benefit Cost ratio of 0.50 indicating that investing in an innovative PDB was financially viable. Finally for a 4 day trial collection, a total methane capture of 789.98 kg was quantified from boiler slurry lagoon. Moreover the total emission factor for CH4 in the study for 248,000 broiler production is 4,960 kg based on IPCC Guidelines, 2006. | |
