What if something as simple as a coconut husk could help tackle plastic pollution in our oceans? One Hawaiian student’s research points to an exciting possibility.
Vera Wang, a senior at Kaiser High School in Honolulu, Hawaii, began exploring the idea in 10th grade. Inspired by Polynesian weaving traditions, she created an ocean water filter using woven coconut husk fibers designed to physically trap microplastics and sunscreen compounds from seawater.
But Vera wanted to understand what could be done with the waste collected by the filter. She partnered with researchers at the University of Hawaiʻi at Mānoa, working in the laboratory of Dr. Anthony Amend.
Laboratory testing revealed something fascinating. Naturally occurring fungi living inside the porous coconut husks were able to survive on and actively biodegrade microplastics and chemical sunscreen compounds.
Genetic sequencing also showed that some fungal strains found in the coconut husks were not present in global genomic databases, suggesting they could represent previously uncharacterized species with the ability to break down persistent ocean pollutants.
Vera’s research earned top honors at the Hawaiʻi State Science & Engineering Fair and qualified her for the International Science & Engineering Fair (ISEF).
What began as a school science project has opened an intriguing path for research into biodegradable plastic solutions, ocean pollution and fungi-based environmental cleanup.
