Leyte, have shown, however, that yields of 35 tonnes per ha can be achieved with new varieties that can produce 4,900-6,545 liters per ha per year of ethanol. If the equivalent of 20% of the Philippines’ current starch and sugar crops production could be used for biofuels, fro example through a mix of increased grain yields and dedicated sugar cane plantations, it would yield about 0.33 hm 3 of ethanol or 0.16 Mt gasoline equivalent per annum. This volume would replace 4% of the Philippines’ current gasoline consumption and 1.5% of its crude oil imports. Biodiesel: Primary feedstock for biodiesel production in the Philippines is coconut oil. The Philippines is one of the largest producers of coconut oil in the world, netting some 1.5 million tonnes per year. About 20% of this production is used for domestic consumption while the balance of 80% is exported. Mindanao accounts for almost 60% of the economy’s total coconut oil production. If 20% of the Philippines’ coconut oil production were used for biofuels, it would yield about 0.31 Mt of biodiesel per year. This would be sufficient to displace 7% of the economy’s 2005 diesel consumption and 3% of its crude oil imports. Second-Generation Biofuels Potential Ethanol: A biomass resource assessment study was conducted in 2000 by the University of the Philippines - Biomass Energy Laboratory in collaboration with the National Renewable Energy Laboratory of the U.S. Department of Energy (Biomass Atlas of the Philippines 2000). Six biomass resources were evaluated and mapped at an economy-wide, regional, provincial, and municipal level, in some cases. These resources include: rice hull, bagasse, coconut residues, animal manure, forestry wastes, and urban refuse. The assessment is based on statistical analysis of reported information, applying product-to-residue ratios. The study uses GIS and GPS technologies to generate a series of maps illustrating each biomass feedstock potential at different administrative levels, as shown in the example in Figure 27. Table 26 provides a summary of the lignocellulosic biomass resources in the Philippines, totaling about 17.7 Mt in 1999. These crop, logging, and coconut residues, along with sugar cane bagasse, would yield 5.4 hm 3 of ethanol or 2.6 Mt gasoline equivalent per annum. This volume would be sufficient to replace 63% of the economy’s current gasoline consumption and 24% of its crude oil imports. 95
