TABUK CITY, Kalinga – The Department of Science and Technology, which is currently enhancing household biogas, plans to introduce centralized biogas digesters to clustered households and barangays.
Dexy Catacutan, DOST-Kalinga science research specialist, said 25 biogas operators and a number of interested individuals have been invited in a recent forum for them to learn more about the technology, particularly on the DOST IV biogas model.
Aside from being the concrete structure and efficient in collecting methane gas, she said the design is environment-friendly and has many economic benefits.
“It controls pollution since all the pig manure are collected into a fixed dome digester, users have free fuel, saves on energy consumption, and the sludge is turned to fertilizer,” Catacutan said.
Methane produced from one cubic meter of pig manure is equivalent to 0.43 liters of liquefied petroleum gas (LPG) while that produced from 25.6 cubic meters is equivalent to 11 kilograms of LPG.
“It only requires four pigs to produce a drum of manure,” Catacutan said, adding the technology is the best alternative for waste management.
She said DOST can support organized groups or barangays that are interested in putting up biogas plants.
“Under the community-based project of DOST, we can also render consultancy services, help in design formulation, and provide supervision,” she said.
