LAHORE - Biogas, which is produced by the fermentation of organic matter like animal waste, cow and buffalo dung, human waste and tree leaves, may be helpful in meeting the persistent energy crisis in the country and its cost is 35 to 50 percent less than that of charcoal, kerosene oil and firewood to get energy, Pakistan Council of Science and Industrial Research (PCSIR) Biotechnology and Food Department Chief Scientific Officer Dr Sakhawat Ali said on Sunday. He said the energy crisis was a big problem in the country and it could be tackled by enhancing livestock and dairy development. “Animal dung can be used for the generation of gas and effluent can be used as fertilizer,” he said, adding at present, Pakistan had 29.9 million buffalos, 33 million cattle and 562 million poultry.
“One buffalo or cow produces 15 kg dung per day and there are 56,900,000 animals and even if 50 percent of the dung is collected every day, it can reach 426,750,000 kg.” “According to the statistics of PCSIR labs, one kg dung can produce 0.05 m3 biogas hence we can generate 2.1x10m3 gas every day,” he said, adding that biogas produces a smokeless flame and is environment-friendly. “It is the best substitute for natural gas and it costs less than all other energy resources,” he said, adding that it could make the country self-reliant and can also help in the production of nitrogen-rich fertilizers. “A biogas plant can be set up within Rs 40,000 to Rs 150,000 and its components are easily available in the local market,” he said.
