A new fixed dome biogas digester is to be built in the municipal abattoir in Baler, Aurora, a province located in the eastern part of Central Luzon, Philippines.

The PHP444,000 (US$8,000) project – funded by the Department of Science and Technology (DOST) – aims to reduce reliance on carbon-intensive fossil-based energy and contribute to a circular carbon economy. 

“The biogas digester will lessen dependence on conventional energy, like liquefied petroleum gas, and for consumers to reduce the problem of ecological solid waste management,” commented Maricel Sicat, Aurora Provincial Science Technology Director. 

With a loading capacity of 20m3, the digester will intake manure produced by large cows and pigs as a feedstock before anaerobic fermentation takes place. 

Capable of being used in fuel cells and for heating and cooking, biogas can also be used in a gas engine to convert energy into electricity and heat.

The Philippines boasts enormous potential for the use of biomass and biogas energy.

In addition to the use of animal waste, sugar cane and rice production can also be used as an efficient input material. 

According to a study by GPCCI, by 2030, total capacities for renewable energies are to be increased to 15,304 gigawatts in the country.
