The first biogas plant in Bicol is proving to be an invaluable asset for the Legazpi City Abattoir located in San Roque.
The slaughterhouse has managed to save Php 1 million in fuel expenses through the integration of the biogas plant in its operations, which fuels its boiler system.
The technology works by utilizing the waste products produced during the slaughtering process, specifically those that are biodegradable. It then converts those wastes to methane gas.
It can generate 3kg per day of LPG or equivalent to 113 LPG tanks annually.
The project ‘Piloting of Biogas Technology for Thermo-Electro-Mechanical Applications for the Legazpi City Abattoir’ was the brainchild of the Department of Science and Technology Regional Office V (DOST-V) and was achieved through the help of the Provincial S&T Center – Albay, and the Local Government of Legazpi City.
DOST-V provided Php 500,000 for the plan while the local government unit of Legazpi allocated Php 450,000 for the biogas generator, biogas scrubber, and biogas refining setup.
The contraption was designed by DOST-V’s Albay Provincial S&T Director Engr. Jacinto Alexis B. Elegado.
In an interview with DZGB-AM, Elegado shared that their setup has already yielded favorable results. Pressure gauges and automatic shut-off valves have also been added to ensure safety.
Elegado noted that they’re already in the planning stage for the project’s second phase. According to him, it will focus on converting the biogas to mechanical energy to drive a motor and convert it to electrical energy through a generator attachment.
Apart from this, the biogas plant is also a source of fertilizer. It’s able to produce 104 tons of high-grade fertilizer plus liquid effluents as a no-odor-fertilizer yearly.
