FROM BANANA FIBERS TO RICE SACKS

 FROM BANANA FIBERS TO RICE SACKS

Sometimes, opportunities are right under our noses—and yet we can’t even smell them. That seems to be the case with the millions, perhaps billions, of banana trunks that we have wasted over the years.

I call them trunks because, technically, a banana is not a tree; it’s an herbaceous plant. But regardless of what we call it, one thing is clear: we have been throwing away what could have been a valuable source of livelihood. For decades, after harvesting the fruits, we simply chopped up the banana trunks and left them to rot—or at best, used them as compost.

Now, it turns out, those same trunks could be spun into gold—well, almost.

Who would have thought that we could still make money from banana trunks? Yet here we are, finally realizing that these so-called wastes can be transformed into something useful and sustainable: rice sacks made from banana fibers.

A Case of Learning Too Late

We should have seen it coming. After all, products have long been made from abaca, a close relative of the banana plant. Abaca fibers are famous worldwide for their strength and durability—used in ropes, specialty papers, and even automobile parts. If abaca could be turned into export-quality material, why not bananas?

And indeed, innovators and researchers have begun proving this point. Banana trunks, once seen as farm waste, can now be processed into strong, flexible fibers ideal for weaving sacks. These banana fiber rice sacks are not only durable and water-resistant but also biodegradable. Once they wear out, they can simply return to the soil—unlike plastic sacks that linger in landfills and rivers for decades.

From Waste to Wealth

The process is refreshingly simple. Farmers extract fibers from banana trunks using hand tools or small machines. The fibers are then dried in the sun and woven on traditional looms. The finished product can be reused multiple times, and when it reaches the end of its life, it decomposes naturally within weeks.

Communities in Mindanao and Luzon have already started adopting this technique. Some cooperatives even print the sacks with plant-based dyes and local branding—turning them into not just practical packaging but also a symbol of sustainable innovation.

Imagine what could happen if every barangay that grows bananas turns its waste trunks into sacks, bags, or handicrafts. Not only would it create local jobs, but it would also help reduce our dependence on imported plastic packaging.

But Who Will Lead?

Here lies the next big question: which government agency should take the lead in scaling this up?

Should it be the Department of Science and Technology (DOST) through its research councils? The Department of Agriculture (DA), since banana farmers stand to benefit directly? Or perhaps the Philippine Fiber Industry Development Authority (PHILFIDA), since it already manages abaca and other fiber industries?

Another strong candidate is DOST-PCIEERD—the Philippine Council for Industry, Energy and Emerging Technology Research and Development. This agency has been at the forefront of developing and commercializing new technologies through programs like CRADLE and SETUP. PCIEERD could easily fund research and help small enterprises process banana fibers efficiently, especially through its Science for Change Program.

Meanwhile, the Department of Trade and Industry (DTI) could take care of the marketing and product promotion side, helping communities form cooperatives and link up with institutional buyers.

And why not bring in the National Food Authority (NFA) as a ready market for these sacks? If the government commits to buying locally produced, biodegradable rice sacks, that alone could jumpstart the industry.

The Bigger Picture

Globally, banana fiber is gaining recognition as one of the most sustainable materials available. Countries like India and Nepal have already established small industries around it, producing textiles, ropes, and paper. In Japan, luxury brands have even experimented with banana fiber fabric.

The Philippines, with its abundant banana plantations, could easily join—or even lead—this movement. Instead of exporting raw fruits and importing plastic, we could export finished banana fiber products while keeping our environment clean.

And let’s not forget: anyone can plant bananas. Even backyard growers could earn a little extra by selling their discarded trunks to processors. This makes it an ideal livelihood project for cooperatives, women’s groups, and rural microenterprises.

A Call to Action

So, who will smell the opportunity this time? Will our policymakers see that “waste” is just a resource waiting for imagination? Or will we once again let another sustainable innovation slip by because of bureaucratic inertia?

If we can turn fallen leaves into paper bags, why not banana trunks into rice sacks? The science is there, the raw materials are plenty, and the environmental benefits are undeniable.

All we need now is leadership, coordination, and vision. The money, as they say, is right under our noses—this time, inside a banana trunk.

SAUDI ARABIA TESTS HYDROGEN-POWERED BUSES

 SAUDI ARABIA TESTS HYDROGEN-POWERED BUSES

Hydrogen power for transportation is not new technology—but what is new is that Saudi Arabia is now applying it in a systematic, scientific, and state-backed way. In Al-Ahsa, the kingdom has started testing hydrogen-powered buses under its Vision 2030 clean energy program. Each bus can travel up to 635 kilometers on a single hydrogen refill, carrying 45 passengers while emitting nothing but water vapor.

If that isn’t the very definition of clean transport, I don’t know what is.

Saudi Arabia’s Transport General Authority (TGA) launched the pilot in partnership with SATCO, a private concessionaire, and it’s not stopping there. NEOM—the futuristic megacity being built in the desert—is testing similar buses at elevations as high as 2,000 meters using Hyundai’s UNIVERSE fuel-cell electric coaches. Clearly, the Saudis are not dabbling—they are investing in the transport systems of the future.

This is where I begin to ask: Why can’t we do the same?

Hydrogen power is no longer “rocket science.” The technology is out there, proven, and increasingly affordable. So what is holding us back from developing our own hydrogen-powered bus system? We don’t lack engineers or scientists. What we often lack, unfortunately, is political will.

If I were to design such a program for the Philippines, I would place the Department of Transportation (DOTr) in the lead—but I would not stop there. The Department of Energy (DOE) and the Department of Science and Technology (DOST) must also be involved. DOTr can focus on policy and deployment; DOE can oversee hydrogen fuel production and regulation; and DOST can lead in technology adaptation and research.

We can start small—through pilot barangays and eco-zones.

Hydrogen Buses for Barangays and Beyond

Saudi Arabia’s model offers practical lessons for our archipelagic country. Imagine if we could build hydrogen-powered mini-buses for inter-island or provincial routes—say, between Calapan and Roxas in Mindoro, or around Palawan’s eco-tourism circuits. These long-range vehicles could travel hundreds of kilometers on one charge, powered by hydrogen generated through solar electrolysis.

At the barangay level, small-scale hydrogen hubs could power tricycles and community shuttles. A solar-powered electrolysis unit can split water into hydrogen and oxygen, storing the hydrogen in tanks for refueling. Some Japanese and European firms are already manufacturing such compact systems. Why not pilot one in, say, Taguig’s urban barangays or in a model eco-village in Nueva Ecija?

For inter-island transport, the same principle applies. Hydrogen-powered ferries could serve remote island clusters like the Batanes group, or the smaller islands of the Calamianes and Tawi-Tawi. In short, hydrogen mobility isn’t just for big cities—it could be the key to inclusive mobility in rural and island communities.

The Economics of Hydrogen

Skeptics will say hydrogen is too expensive. True, green hydrogen—produced from renewable energy—still costs more than fossil fuels. But prices are falling fast. According to the International Energy Agency (IEA), the cost of renewable hydrogen could drop by as much as 60% by 2030, thanks to scaling and innovation. Saudi Arabia is betting big on this trend, investing billions in NEOM’s hydrogen hub, which is projected to produce 600 tons of green hydrogen per day by 2026.

Why can’t we follow that path on a smaller scale? The Philippines has abundant renewable resources—sun, wind, hydro—that could power electrolysis plants. If we can produce hydrogen locally, we can also enhance our energy sovereignty.

Hydrogen and the Circular Economy

Hydrogen can even fit into our circular design goals. Instead of wasting treated water, we can use reclaimed water from sewage plants for hydrogen production. Agricultural waste can feed small biomass systems that power electrolysis. This integration would not only produce clean fuel but also reduce waste, aligning with sustainability goals under our own “Ambisyon Natin 2040.”

What We Need: Vision and Will

So again, the real question is: where will the political will come from?

Saudi Arabia’s leadership is setting a strong example. They’re not just talking about “green transition”—they’re building it, testing it, and proving it. We, too, could begin by forming a National Hydrogen Mobility Task Force, combining the expertise of DOTr, DOE, DOST, and even local universities.

We have a saying: “Kung gusto, may paraan; kung ayaw, may dahilan.” (If there’s a will, there’s a way.) Hydrogen power gives us a clear way forward. All we need now is the will.

If Saudi Arabia—a desert kingdom with fewer natural water resources—can run buses on hydrogen, what’s stopping an island nation like ours, surrounded by water and blessed with sunlight, from doing the same?

Maybe what we need is not more science—but more courage to apply it.

OPERATIONS RESEARCH HAS EVOLVED INTO DATA ANALYTICS

 OPERATIONS RESEARCH HAS EVOLVED INTO DATA ANALYTICS

It is just my own speculation—but perhaps not a wild one—that what used to be known as Operations Research (OR) has now evolved into the modern science of Data Analytics. And more than that, Artificial Intelligence (AI) has raised OR to a higher, stronger, and faster discipline.

I am not an economist, but I do know that economics is generally about managing scarce resources, while operations research is about maximizing those same resources. Economics defines scarcity; OR defies it.

If economists would ask, “How do we divide limited resources?” then OR replies, “How do we make the most out of what we have left?” In a world drowning in data and limited in time, that distinction has never been more relevant.

---

From Equations to Insights

Operations Research was born in the 1940s, during World War II, when mathematicians were tasked to optimize everything from radar deployment to convoy routes. It was, in essence, the science of efficiency. It used mathematical models—linear programming, simulation, queuing theory—to make the most of scarce resources under pressure.

Fast forward to today, and those same mathematical foundations have found new expression in data analytics. Where OR once optimized military supply chains, data analytics now optimizes everything from hospital staffing to urban traffic flow, from agriculture yield to disaster response.

It’s not that OR disappeared—it evolved. The models became smarter, the data became richer, and the goals became broader. We are no longer solving just equations; we are generating insights.

Descriptive analytics tells us what happened. Predictive analytics tells us what might happen. And prescriptive analytics—OR’s spiritual heir—tells us what we should do next.

---

When Artificial Intelligence Joins the Equation

The real leap came when AI entered the picture. Artificial Intelligence didn’t replace OR—it turbocharged it.

Machine learning can now generate parameters automatically, simulate thousands of scenarios, and refine models based on real-time feedback. In traditional OR, analysts might spend days tuning a model; now, AI does it in seconds.

For example, reinforcement learning (a branch of AI) can find the best decisions in complex environments—just like OR did—but dynamically and continuously. That’s why hybrid systems combining AI and OR are now used in logistics, energy grids, and even public policy.

Think of it this way: AI makes predictions, OR makes decisions. Together, they make smarter systems.

---

Maximizing National Resources Through OR + AI

Here’s an idea worth exploring: what if we could apply OR and AI to the General Appropriations Act (GAA)? Imagine a data-driven system that allocates government budgets based not just on political priorities but on mathematical optimization—maximizing social benefit per peso spent.

We could simulate different scenarios: how much more health coverage could be achieved if funds were reallocated? How can road repairs be scheduled to reduce traffic and costs simultaneously? OR can model that; AI can predict outcomes; data analytics can measure success.

If corruption is the sin of commission, then inefficiency is the sin of omission—and both rob the people of progress. OR and AI, used together, could make the government more transparent, accountable, and effective.

---

Scarcity vs. Maximization

Economics, as defined by Lionel Robbins, is the science of human behavior as a relationship between ends and scarce means. But OR is the science of maximization—it starts where economics ends.

Economics may analyze how scarce resources affect the economy. OR will tell you how to use those same resources optimally.

For example:

• Economics studies how burial land scarcity affects urban planning.
  
  

• OR models the optimal use of cemetery space through columbaria or digital memorial systems.
  
  

• Economics looks at incentives for aquaculture transitions.
  
  

• OR simulates feed ratios and harvest schedules to maximize yield.
  
  

In short, economics helps us understand why systems fail or succeed. OR helps us design how to fix them. And AI ensures that the system keeps learning as it goes.

---

The Human Side of Numbers

Still, we must not forget that behind every algorithm are people. The danger in today’s data-driven world is that we might focus so much on optimization that we forget about compassion.

AI and OR should never be tools for exclusion or control—they should be instruments for service. Data must serve the people, not the system. If we use analytics to predict who gets aid, let it be to reach the vulnerable faster, not to deny them. If we optimize budgets, let it be for equitable distribution, not mere efficiency.

As systems thinkers often remind us: optimization without ethics is just automation of injustice.

---

A Final Thought

If economics is about managing scarcity, and OR is about maximizing resources, then perhaps AI and data analytics are about illuminating potential. They take the invisible patterns of society and make them visible, measurable, and actionable.

Imagine a Philippines where every barangay uses AI-assisted dashboards to allocate resources, manage waste, plan transport, and even predict flood risks. That is not science fiction anymore—it’s within reach.

So yes, Operations Research has evolved into Data Analytics—but only in the hands of those who dare to use it wisely. Because ultimately, the goal is not just maximization of numbers, but maximization of human dignity.

HERE’S A NEW CEMENTING MATERIAL INSPIRED BY THE ROMAN EMPIRE’S ANCIENT CONCRETE

 HERE’S A NEW CEMENTING MATERIAL INSPIRED BY THE ROMAN EMPIRE’S ANCIENT CONCRETE

Who says that if a technology is already old, then it’s obsolete? The truth is, some “old” technologies are timeless. They endure because they were born of necessity, perfected by experience, and rooted in natural wisdom. Sometimes, it’s not about reinventing the wheel — it’s about rediscovering how the ancients made it roll so smoothly.

One of history’s most enduring technologies comes from the mighty Roman Empire — its ancient concrete. Consider this: the Pantheon in Rome, built nearly 2,000 years ago, still stands with the world’s largest unreinforced concrete dome, while many modern structures crack and crumble in less than a century. That’s not just impressive; it’s humbling.

Recently, a company in British Columbia called Progressive Planet announced it has developed a new material called Gladiator SCM (Supplementary Cementing Material), inspired by the strength and longevity of Roman concrete. They even filed for a U.S. patent for its composition. Their scientists combined PozGlass, a recycled-glass additive, with other natural materials to create a cementing blend that promises high durability and low carbon emissions — a perfect example of ancient wisdom meeting modern sustainability.

The company’s press release proudly notes that the name “Gladiator” pays tribute to Roman resilience. It’s also symbolic — a battle cry in the global fight against climate change and poor construction practices.

Now here’s my question: why can’t we in the Philippines pursue something similar?

Cement, Corruption, and Crumbling Roads

It’s no secret that many public works projects in the Philippines have been plagued by substandard materials and construction shortcuts — often victims of corruption and negligence. Every typhoon season, we see newly built roads washed out, bridges collapsing, and school buildings reduced to rubble.

In contrast, Roman roads, aqueducts, and ports — built without modern machines — have survived earthquakes and erosion for millennia. Their secret was a volcanic ingredient called pozzolana, which chemically reacted with lime and seawater to make their concrete self-healing. Today, Progressive Planet’s Gladiator SCM uses similar chemistry, but enhanced by recycled glass and scientific precision.

If we could bring such materials here, imagine how much stronger and greener our infrastructure could be. Why not require sustainable SCMs in public construction? This could reduce carbon emissions, improve longevity, and cut down on maintenance costs.

According to the International Energy Agency, cement production accounts for around 8% of global CO₂ emissions — more than aviation fuel. Using SCMs like Gladiator could cut that by up to 40%, depending on the mix. That’s a big deal for climate adaptation in a country like ours, where rising sea levels and stronger typhoons are becoming the new normal.

Rediscovering the Past to Build the Future

What fascinates me most about this development is how science keeps circling back to history. The Romans didn’t have advanced laboratories or AI-driven modeling — they simply observed nature and built with it, not against it. They mixed volcanic ash with lime and seawater, unknowingly creating a “living” material that grew stronger over time.

Modern scientists, through X-ray diffraction and electron microscopy, are now finding out why Roman concrete was so resilient. When cracks formed, the unreacted lime particles would dissolve in rainwater and recrystallize, effectively sealing the cracks — an early form of self-healing cement.

Progressive Planet’s Gladiator SCM takes that same idea — durability through chemistry — and pushes it into the sustainability age. They’ve even brought in Dr. Gerhard Albrecht, a world-renowned polymer scientist formerly with BASF, to perfect the formula. If that’s not a fusion of old and new genius, I don’t know what is.

A Call to Build Smarter, Not Just Faster

Here in the Philippines, our obsession with fast construction often comes at the expense of quality. We rush to meet project deadlines, pour concrete in the rain, skip curing times, and use the cheapest materials available. Then we spend twice as much repairing the damage later.

It’s time to rethink our approach. Instead of cutting corners, let’s cut carbon. Instead of pouring more cement, let’s pour smarter cement.

Imagine if DPWH or local governments partnered with universities and companies like Progressive Planet to pilot SCM-based materials in public works — starting with schools, barangay halls, or flood control systems. It could create jobs, attract green investment, and most importantly, save taxpayer money in the long run.

If ancient Rome could build monuments that outlast empires, surely a modern republic like ours can build roads that last more than a few rainy seasons.

In the End, the Lesson is Simple

Not all progress means abandoning the past. Sometimes, progress means looking back with humility and saying, “They got it right.”

The Romans built for eternity; we are building for election cycles. It’s time to change that. Let’s take inspiration from Gladiator SCM — and from the ancients who knew that real strength doesn’t just come from power, but from patience, precision, and purpose.

Because in the end, it’s not just about cementing structures — it’s about cementing values: honesty, sustainability, and respect for the future.
