The Department of Science and Technology (DOST) supports the building of a waste-to-energy facility.

Secretary of the Department of Science and Technology (DOST) Fortunato dela Peña remarked that having waste-to-energy (WTE) technology in the country was one of his goals when he took office.

“Why can’t we do it here in the country like our neighboring countries like Singapore and Taiwan?” he wrote on Facebook.

Dela Peña said he was able to see that vision come true earlier this week when he visited and inspected a fully operational WTE facility in Los Baños, Laguna.

“DOST supported the building of the 25kW waste-to-energy facility for municipal solid trash utilizing a direct combustion process as a feasible solution to the country’s ever-increasing municipal solid waste production,” he said.

The direct combustion system will be fueled by the solid waste created by the University of the Philippines Los Baos, according to Dela Peña (UPLB). The combustible part of the solid waste will be fed into a combustion chamber with a moving grate, and the heat from the flue gas will be used to make hot water, which will provide the heat for the ORC generator to generate up to 25kW of power.

A continuous emission monitoring system (CEMS) and a Gas Chromatograph-Multi Spectrometer would be used to measure gas emissions during combustion, he stated (GC-MS).

To determine whether a WTE direct combustion technology is possible in the Philippines, the technical study will largely focus on the efficiency of energy recovery as electricity from municipal solid waste. He stated that mitigation control techniques for gas emission will be studied to guarantee the procedure is ecologically friendly.

The goal of the two-year initiative is to:

Establish a 25-kW municipal solid waste waste-to-energy (WTE) facility using direct combustion technology;

Observe and describe the flue gas emissions from the WTE process.

Assess the WTE process’s economic viability and environmental implications; and

Provide action plans and suggestions for the deployment of a WTE direct combustion process in the Philippines as a feasible solution for municipal solid waste management.

Policymakers, government institutions, parliamentarians, and the country’s energy sector, according to Dela Peña, may all profit from this approach.

“The proposed method can be used at the municipal level to address the university’s and Los Baos’ trash disposal issues. The facility can be used to handle the university’s and surrounding towns’ garbage “he stated

In the Philippines, waste generation has been quickly expanding and has become a big problem, particularly in densely populated areas like Metro Manila, Southern Tagalog, and Central Luzon. Rapid population expansion, urbanization, and economic development are all contributing to the huge increase.

“We anticipate that this project will provide science-based data on waste-to-energy technology via direct combustion system, assist in the county’s solid waste management scheme by providing a technology that meets international environmental standards, and aid in the assessment and improvement of WTE technologies, as well as possibly revive the country’s incineration plants,” he said.
