05 Biogas Inauguration
Igniting the Flame:
DOST-V, Legazpi City inaugurates biogas digester for Legazpi City Abattoir

June 11, 2021

The Department of Science and Technology Region V (DOST-V) and the City Government of Legazpi marks another breakthrough in pioneering biogas technology in the region with the inauguration of the new biogas digester at the Legazpi City Abattoir on 11 June 2021, part of the project Piloting of Biogas Technology for Thermo-Electro-Mechanical Applications for the Legazpi City Abattoir.

This event, a collaborative undertaking of DOST-V through the Provincial S&T Center (PSTC) – Albay and LGU-Legazpi was graced by city officials Hon. Mayor Noel E. Rosal, Vice-Mayor Oscar Robert H. Cristobal, City Councilor Jose Alfonso V. Barizo and City Veterinarian Dr. Emmanuel V. Estipona; DOST-V Albay Provincial S&T Director Engr. Jacinto Alexis B. Elegado; National Meat Inspection Service (NMIS) Regional Technical Director Dr. Alex B. Templonuevo; and local media representatives.

One of the reasons behind the project’s conceptualization is the management of the 1.5 ton of organic waste produced by the abattoir, comprised mainly of livestock manure that is potentially harmful to the environment and public health. Now, the project comes to fruition through the initiatives of PSTC-Albay and the City Veterinary Office. With the operationalization of the biogas digester, the Legazpi City Abattoir is expected to save as much as P1 million by shifting to methane gas as the main source of fuel used for scalding and other slaughtering processes.

Although the current production rate is at a minimum due to limited controlled inflow of materials, the biogas digester is expected to produce 3kg methane gas per day, equivalent to 113 LPG tanks per annum. Moreover, the abattoir can now produce 104 tons of odorless organic liquid fertilizer from the liquid effluents of the biogas digester.

For Dr. Templonuevo, the project is a huge milestone for Bicol, as the abattoir is the first to adopt a biogas digester in the whole region, if not in the entire country. Bio-intensive gardens in the area where the produced organic liquid fertilizers can be utilized are also suggested as additional improvements to the facility.

The inauguration concluded with the ceremonial lighting of the biogas flame, led by Mayor Rosal and the rest of the city officials.

The second phase of the project will focus on converting thermal energy harnessed from the biogas digester to electro-mechanical energy to finally produce an off-grid electricity as transport fuel. (PSTC-Albay)
