Inventor seeks market for biomass stove


ABUCAY, Bataan: An agricultural engineer in Bataan on Tuesday is seeking the commercialization of his invention, a biomass-cooking stove that has gained recognition from the United Nations Global Alliance for Clean Cook Stoves.

Engr. Jonathan Lacayanga, 42, chief of the Research Division of the Bataan Polytechnic State University branch, said he has urged his school to set aside funds for the commercialization of his “vertical-fed stove.”

Through commercialization, he expects to derive carbon trading for his invention that does not emit too much smoke when cooking, unlike other stoves using biomass. “If many use it, we can lobby on the carbon market and get remuneration for reducing emissions,” he said.

“This is the only one with a vertical fuel. When the fire burns continuously, there is no smoke and the user does not need to blow repeatedly on it,” the university instructor said.

“Most stoves have a principle of ‘top lid, up draft’ but ours has ‘bottom lid, down draft’ because the air current flows downward,” the engineer said.

Lacayanga teaches and does research works at the BPSU branch near an Aeta upland village in Abucay, Bataan that used to be the Bataan National Agriculture School.

“We have completed our research and we are consolidating our findings,” he said.

Work on the stove started in 2004. It was recognized in 2012 by the UN alliance, earning for BPSU membership in it.

Lacayanga said the UN is moving to distribute millions of efficient cooking stoves to biomass-dependents in the world.

A World Health Organization study found that in countries using biomass-fed stoves the fourth cause of mortality is the smoke from inefficient stoves that produces indoor air pollution, Lacayanga said.

He said that 86 percent of the households in the Philippines use stoves fuelled by wood, coconut shells and other biomass materials.

Lacayanga said his invention was under patent with the Intellectual Property Rights of the Philippines. He said he has presented his biomass cookstove in Cambodia and that he was also invited to China. Several non-government organizations in Africa wanted the technology transferred to them.

But the engineer said he wants the masses in our country to benefit from his invention. “I am willing to teach them how to build it. I only want to be recognized as its inventor.”

ZorilleVillaflores, staff assistant of Lacayanga, and housewife Maribel Ecalla demonstrated how the cookstove operates. “It is more economical than other stoves particularly those using liquefied petroleum gas. You just collect small pieces of wood and you can cook,” they said.

There are three models of the biomass stove invented by Lacayanga—the first made of plain galvanized iron sheets priced at P1,200, one made of concrete selling at P900 to P1,000 and the third combining clay and plain G. I. sheet at P550 each.
