Philippine biodiesel meets international standards

By Abigail L. Ho, Philippine Daily Inquirer

MANILA, Philippines -- Initial tests on locally produced biodiesel have yielded positive results, indicating that the Philippines can produce jatropha-based biodiesel that meets international standards.

PNOC Alternative Fuels Corp.’s jatropha-based biodiesel, tested in collaboration with the Technological University of the Philippines and Chemrez Technologies Inc., met both European and American Biodiesel Standards, according to data from PNOC-AFC.

The tests included jatropha oil and methyl ester production and characterization, development of high-value products, and actual performance testing of jatropha methyl ester.

“And the variety we used for that test wasn’t even the best variety we have found so far,” PNOC-AFC president and chief executive Peter Anthony Abaya said.

In preparation for commercial production, he said PNOC-AFC and the Department of Science and Technology were still conducting tests on which variety of jatropha would be best for propagation.

The pool has so far been narrowed to six local varieties.

Based on initial trends, on the fourth year or by 2011, PNOC-AFC could have an annual average yield of 7.5-15 tons of jatropha per hectare and that 1,000-1,400 seeds will be needed to produce a kilo of jatropha.

The oil extraction rate ranged from 30-40 percent on varieties taken from the southern city of General Santos and the provinces of Saranggani, Davao, Palawan, Batangas, Laguna, Nueva Ecija, Tarlac, Camarines Sur and Sorsogon.

Before establishing commercial plantations, PNOC-AFC aims to put in place a 1,500-hectare nursery from which the seedlings for the plantations will come.

It then hopes to develop, together with private sector partners, 700,000 hectares of jatropha plantations -- 140,000 hectares this year, another 250,000 hectares next year and another 310,000 hectares in 2010.

In terms of actual jatropha-based biodiesel, PNOC-AFC envisions production of 100,000 metric tons next year, 400,000 in 2010 and 500,000 in 2011.
