Biogas fuels Legazpi abattoir

By Cet Dematera

ASIDE from solving the problem of disposing the manure of slaughtered animals, the Legazpi City government has also negated the issue of bit expensive fuel consumption in running its “AA” slaughter house that presently serves the entire city and its adjacent towns.

This after its newly-constructed biogas digester machine has already started to operate on Saturday, June 12, yielding an initial production of at least three kilos a day of liquefied petroleum gas (LPG) and high grade organic fertilizers.

The methane gas will be used to boil water needed in the slaughter of animals at the only AA slaughter house in the Second District of Albay.

Mayor Noel E. Rosal, Vice- Mayor Bobby Cristobal and other members of the Sangguniang Panlungsod (SP), Department of Science and Technology (DOST) Albay Director Alexis Eligado, and National Meat Inspection services (NMIS) Director Alex Templonuevo, led the ceremonial lighting of blue flame during the inauguration of the biogas plant inside the slaughter house compound on June 11.

Rosal said the biogas plant is yet another landmark project of Legazpi as it would initially provide free fuel to the slaughter house on a daily basis.

“This project can also produce high grade organic fertilizers that can be used by the farmers for their daily agricultural activities” Rosal said.

He said the biogas plant can generate P1million worth of methane gas a year or to produce three kilos of LPG a day, or 113 tanks of LPG a year.

The project materialized through the P300,000 grant from the DOST, with the constructions works managed by the City Engineering Office (CEO).

The memorandum of agreement (MOA) of the project was signed on June 30, 2020 by Rosal for the city government, and regional director Rommel Serrano for DOST-Bicol.

City Veterinary Office (CVO) chief Dr. Emmanuel Estipona, in a separate interview, said the project is part of the solid waste management practices that are seen to mitigate public health hazard and environmental degradation and also to reduce the green gas house emission.

“The organic fertilizers that it can be produced from the biogas plant would be distributed to the farmers for free as part of the support to the “Plant, Plant, Plant” program of the government” Estipona added.

He noted that he is trying to expand the biogas plant to use the other waste materials from the slaughter house and convert it into gas and fertilizers.

Eligado for his part said the Legazpi City AA abattoir is the first slaughter house in the country to adopt the biogas plant system as a solid waste management and diversion program.

Eligado who also designed the biogas plant said the phase 2 or the expansion of the project will focus on the conversion of biogas from thermal energy to electro-mechanical energy to finally produce an off-grid electricity.
