Portable Biogas Digesters Donated to Lubao Bamboo Hub

By Albert B. Lacanlale

LUBAO, Pampanga—Four units of portable bio-digester system have been donated to the local government unit here to be used at the Lubao Bamboo Hub and Ecopark.

Mayor Mylyn Pineda-Cayabyab accepted the donation from the Department of Science and Technology (DOST) Pampanga Provincial Office and Pampanga Agricultural State University (PSAU) during simple a turnover yesterday.

The portable biodigester converts leftover food and other biodegradable kitchen wastes to fuel that could fire up a single-burner counter stove, said Mary Michelle Quiambao, DOST provincial director.

The system consists of two main parts connected by a series of tubes. The first part is the digester where kitchen waste is mixed with water to ferment and produce methane, a highly-flammable gas. The gas then travels through a tube and is collected in another plastic tank connected to the cooking stove.

The technology was developed by DOST’s Industrial Technology and Development Institute (ITDI).
PSAU fabricated the biodigester from used fiberglass watertanks and container drums with a total price tag of only P20,000 for every complete unit.

Mayor Cayabyab said the LGU only needs to provide the manpower to operate the digester as its counterpart in the project.
The biodigester system, the mayor said, can help the Bamboo hub management could use kitchen wastes generated by the park in its operation for its own fuel requirement.
