YES, MICROPLASTICS CAN BE REMOVED FROM THE WATER

YES, MICROPLASTICS CAN BE REMOVED FROM THE WATER

Just when we thought that we are losing the war against microplastics, along comes a piece of wonderful news — and from the most unexpected of places. Two high school students from Texas have developed a groundbreaking system that can remove over 90% of microplastics from water. And they did it not with expensive laboratories or massive funding, but with curiosity, creativity, and compassion for the planet.

Their names are Victoria Ou and Justin Huang, both 17-year-olds from The Woodlands College Park High School. Their invention, called “Acoustic Filtration,” uses ultrasonic sound waves — yes, sound! — to create pressure fields in water. These fields gather and isolate microplastic particles, making them easier to remove. No filters. No chemicals. No clogging. Just sound waves doing the work of purification.

In laboratory tests, this simple yet elegant system removed 84% to 94% of microplastics in a single pass. It’s low-cost, portable, and can operate continuously — making it perfect for everything from industrial wastewater systems to household water purifiers, even ocean cleanup operations. For their brilliance, the young duo won the Gordon E. Moore Award at the 2024 Regeneron International Science and Engineering Fair, earning a $50,000 prize and worldwide recognition.

Now here’s my question: If high school students from Texas could do it, why not our students here in the Philippines?

We have so many bright young minds in our science high schools, universities, and technical institutes. Many of them are already tinkering with electronics, robotics, and environmental solutions. Perhaps all they need is support, mentorship, and a challenge. Maybe it’s time for DOST, DENR, and DTI to collaborate on a national program to develop homegrown versions of this innovation.

Let’s not stop there. The Philippine Coast Guard should be part of the initiative too — after all, they are the ones who encounter tons of plastic waste floating in our seas every single day. They could test and deploy these acoustic filters in coastal cleanup operations or shipboard waste systems.

The Department of Trade and Industry (DTI), though not the usual player in environmental matters, has a key role to play. Many of the companies producing plastic waste are under its jurisdiction. Why not encourage these firms to fund pilot tests or adopt “acoustic cleanup” technologies as part of their corporate social responsibility?

And of course, DOST could help refine the design and adapt it to tropical conditions, while DENR could set guidelines for safe, large-scale deployment. If we’re serious about solving our plastic pollution problem, these agencies should set targets, deadlines, and demonstration sites.

Remember, the Philippines is consistently ranked among the top five contributors of ocean plastic waste in the world. That’s a shameful distinction. But it also means we have a moral obligation to be part of the solution, not just part of the problem.

I’m not saying we should copy the Texas students’ invention outright — that would violate their intellectual property. What I’m saying is, we can be inspired by their approach. We can design our own versions — perhaps adapted for barangay-level water systems, fish farms, or river estuaries where microplastics first accumulate.

In fact, this could be a great national science challenge: “The Philippine Acoustic Filtration Project.” Imagine if every science high school, university, and polytechnic in the country were invited to design their own low-cost microplastic removal system. The winning prototype could even be scaled up with government and private sector support.

What excites me most about this story is not just the technology — it’s the mindset behind it. These young inventors remind us that innovation doesn’t always require massive funding or global corporations. Sometimes, it just takes two curious teenagers and a good science teacher.

We’ve long complained that our environmental problems are too big to solve, that our systems are broken, that change takes too long. But here’s proof that a fresh idea, born in a school lab, can spark global hope.

If Texas high schoolers can remove 90% of microplastics from water with sound waves, then surely Filipino ingenuity can rise to the challenge too.

All it takes is for our government to believe in our own talent — and to set things in motion.

Because yes, microplastics can be removed from the water — and yes, the next solution could be Filipino-made.
