HOW MUCH OF SYNTHETIC FUELS COULD WE REPLACE WITH BIOFUELS?

HOW MUCH OF SYNTHETIC FUELS COULD WE REPLACE WITH BIOFUELS? We are now hearing more frequently about shortages in synthetic fuels—and that should worry us. But perhaps the bigger question is this: why are we still so dependent on imported fuels when we are sitting on a goldmine of local biofuel resources? Let’s start with the obvious. The Philippines is not poor in energy resources—we are simply underutilizing what we already have. Seaweeds, water hyacinths, coconut oil, nipa palms, and sugarcane are not just agricultural or environmental assets. They are potential energy lifelines. If properly harnessed, these could significantly offset our dependence on fossil fuels. The real issue is not availability—it is scale, coordination, and political will. Take sugarcane, for example. It produces bioethanol, a renewable, high-octane fuel that is already blended into gasoline as E10. The science is straightforward: extract the juice, ferment it, distill it, and dehydrate it into near-pure etha...

COULD RICE REALLY BE GROWN IN POTS?

COULD RICE REALLY BE GROWN IN POTS? At first glance, the idea sounds almost ridiculous. Rice, after all, has always been associated with wide, flooded paddies stretching across the countryside. But times have changed—and perhaps our thinking should, too. The short answer is yes: rice can indeed be grown in pots. In fact, rice is simply a hardy grass—scientifically known as Oryza sativa —that adapts surprisingly well to controlled environments. Urban gardeners, researchers, and even hobbyists have already proven that container-grown rice is not only possible but practical. There was a time when such an idea would have been dismissed outright. Why plant rice in pots when land was abundant and supply was stable? But today, we face a different reality. With urban expansion eating into agricultural land and climate uncertainties affecting production, the question is no longer “Why?” but “Why not?” Let us be realistic: rice grown in pots will never match the yield of large-scale farms. But i...

WHAT? COULD WATER HYACINTHS REALLY FUEL VEHICLE ENGINES?

WHAT? COULD WATER HYACINTHS REALLY FUEL VEHICLE ENGINES? At first glance, the idea sounds like science fiction. Imagine a vehicle running on fuel derived from water hyacinths—the same aquatic weeds that clog rivers, choke lakes, and cause floods in many parts of the Philippines. Yet surprisingly, the answer is yes. Water hyacinths can actually be converted into engine fuel. For decades, these plants have been treated purely as environmental pests. They block waterways, damage fisheries, and require costly removal programs. But modern research is beginning to show that this “burden” might actually be a blessing in disguise. Water hyacinths grow extremely fast—sometimes doubling in population in just two weeks. Because they contain large amounts of cellulose and organic matter, they can be processed into different types of biofuels. In other words, what used to be a nuisance could become an energy resource. One method involves producing bioethanol , a liquid fuel similar to alcohol. The ...

WHAT COULD BE THE LONG-TERM SOLUTIONS TO ADDRESS THE EFFECTS OF HIGH OIL PRICES?

WHAT COULD BE THE LONG-TERM SOLUTIONS TO ADDRESS THE EFFECTS OF HIGH OIL PRICES? Every time global oil prices spike, governments are tempted to resort to quick fixes such as fuel subsidies or the suspension of excise taxes. These measures may provide temporary relief, but they rarely solve the real problem. They also strain government budgets. As economist Alvin Ang recently pointed out, such solutions may work only for a short period. The deeper effects of higher oil prices eventually spread to transportation, food production, and the prices of basic goods. The harsh reality is that countries like the Philippines have very little control over global oil prices. These are shaped by market forces and geopolitical conflicts, such as tensions in the Middle East. What we can control, however, is how much oil we actually consume and how dependent we are on imported petroleum. In other words, the real solution lies in long-term structural changes. One approach that I have repeatedly advocat...

IS IT TIME TO PUSH FOR A HIGHER BIODIESEL BLEND?

IS IT TIME TO PUSH FOR A HIGHER BIODIESEL BLEND? The question of pushing for a higher biodiesel blend has suddenly become very timely. As of early 2026, the Philippines is currently implementing a B3 blend, meaning that diesel sold in the market contains 3 percent coco-methyl ester (CME) derived from coconut oil. The plan of the government is to gradually increase the blend to B4 and eventually B5 by October 2026 under the Biofuels Act of 2006. But perhaps the bigger question now is this: Are these targets already outdated? The global oil situation has changed dramatically. Wars in the Middle East, supply disruptions, and volatile oil markets have once again reminded us how vulnerable we are to imported fuel. The Philippines imports the vast majority of its petroleum needs. Every spike in global prices quickly translates into higher transport costs, higher food prices, and higher electricity costs. So why not look closer to home? At the center of this opportunity are the estimated 2.5 ...

COULD WASTE PLASTIC BE PROCESSED BACK INTO DIESEL AND GASOLINE?

COULD WASTE PLASTIC BE PROCESSED BACK INTO DIESEL AND GASOLINE? The short answer is yes. In fact, the technology already exists and has been tested for years. The process is called pyrolysis, and it essentially “unmakes” plastic by heating it to extremely high temperatures—usually between 300°C and 900°C—without oxygen. Instead of burning, the plastic breaks down into smaller hydrocarbon molecules that can become fuel oils such as diesel or gasoline. In simple terms, plastic originally came from petroleum. Pyrolysis simply reverses the process by turning the plastic back into oil-based fuels. When plastic waste undergoes pyrolysis, three products normally emerge. The first is pyrolysis oil, which can be refined into diesel, gasoline, or even used as feedstock for making new plastics. The second is synthetic gas, which can power the plant itself. The third is char, a carbon residue that can be used as industrial fuel or additive. Perhaps this technology has been around for decades but r...

COULD THE OIL CRISIS EVENTUALLY RESULT IN A FERTILIZER SHORTAGE?

COULD THE OIL CRISIS EVENTUALLY RESULT IN A FERTILIZER SHORTAGE? Many people worry about rising fuel prices because they expect higher transport costs. Others fear that fuel supplies might run out. But there is a bigger concern that is rarely discussed: could an oil crisis eventually result in a fertilizer shortage—and eventually a food crisis? The short answer is yes. Most people associate oil with cars, airplanes, and electricity generation. However, modern agriculture is deeply dependent on fossil fuels, not only as energy but also as a raw material for fertilizers. In fact, the global food system would look very different without fossil fuels. The key link is actually natural gas. Most nitrogen fertilizers—such as urea and ammonium nitrate—are produced using the Haber-Bosch process. In this process, hydrogen derived from natural gas is combined with nitrogen from the air to produce ammonia, the building block of nitrogen fertilizer. Because of this, natural gas can account for abou...
