Hawaiʻi Teen Finds Coconut-Husk Fungi That Break Down Plastic and Sunscreen

Today’s Progress

Vera Wang, a senior at Kaiser High School in East Honolulu, has shown that fungi living naturally in coconut husks can biodegrade plastic and sunscreen compounds. She carried out the work in Anthony Amend’s laboratory at the University of Hawaiʻi at Mānoa and earned multiple awards at the 2026 Hawaiʻi State Science & Engineering Fair.

According to University of Hawaiʻi System News, her project took first place Best in Category for Microbiology and third place Best in Fair. She also received special awards from the Friends of Hanauma Bay and the Association for Women Geoscientists, a McInerny Foundation scholarship, and a berth at the International Science and Engineering Fair in Phoenix, Arizona.

The path began in her sophomore year, when she designed an ocean-surface filter from coconut byproduct waste. The design drew on traditional Polynesian weaving and was built to capture sunscreen and microplastics. Once pollutants were trapped, she asked how to dispose of them responsibly. That question shifted the work into microbiology.

Working closely with graduate student Kaylee Christensen in the Marine Biology Graduate Program, Wang examined fungal communities in coconut husks and tested their growth and degradation on sunscreen and plastic media. The team found that fungi native to the husks can biodegrade those pollutants. A tannin compound helped identify the degrading fungi, and tannins in the fibers may support their growth. Genetic tests showed some isolates had no match in a major global gene and genome reference database, suggesting they may be previously uncharacterized species.

“I am so grateful to have been given the opportunity to pursue my project in the Amend Lab,” Wang said, as reported by Good News Network and UH News. Amend credited her vision and Hawaiʻi’s public schools for nurturing the next generation of researchers.

Why This Matters

Microplastics and certain sunscreen ingredients are hard to remove once they enter seawater. Wang’s sequence—capture with a biodegradable coconut filter, then biological breakdown—explores combining pollutant capture with biological treatment.

The current benefit is scientific and educational: a documented lab demonstration, student mentorship inside a university lab, and public recognition that can open further research pathways. Any large-scale marine cleanup remains prospective and unproven in the field.

Evidence and Context

Primary reporting comes from the University of Hawaiʻi (May 2026) and secondary coverage by Good News Network and other outlets. Evidence of biodegradation rests on controlled lab growth and degradation assays, plus genetic screening. Strengths include university lab oversight, clear award records, and a coherent research arc from filter to fungi.

Limits are important. Results are early-stage and experimental. Public accounts do not publish full degradation rates, polymer types, sunscreen chemistries, residual byproducts, or open-ocean trials. “May be previously uncharacterized” is a genetic-database finding, not a formal species description. Scaling, safety, and ecological side effects are not yet established.

What Made This Possible

Access to Amend’s lab in the Pacific Biosciences Research Center (SOEST), mentorship from Christensen, coconut byproduct waste as an accessible material, and science-fair recognition of her multi-year project all appear central. Cultural inspiration from Polynesian weaving shaped the original filter design.

Progress Toward Global Goals

The work aligns defensibly with SDG 14 (Life Below Water) by targeting laboratory breakdown of marine-relevant pollutants, and with SDG 4 (Quality Education) through sustained high-school research inside a university lab. Using agricultural byproduct waste also touches SDG 12 (Responsible Consumption and Production) at the materials level. No UDHR article is directly implicated. Field deployment would be needed before claiming measurable ocean recovery.

Building on This Success

The following possibilities were generated with the assistance of AI to explore how this progress might be improved, expanded, or adapted. They are ideas for further investigation, not established findings or recommendations from the people featured in the original reporting.

Mentored student–university pairs could standardize simple tannin-based screening kits so other coastal schools test local plant fibers for pollutant-degrading microbes, with shared protocols and open strain catalogs as the measurable test. Marine labs might run controlled mesocosm trials comparing coconut-husk consortia against known plastic-degrading fungi under Hawaiian salinity and UV conditions, tracking mass loss and byproduct toxicity. Waste-management pilots could pair spent coconut filters from beach cleanups with contained fungal treatment beds, measuring pollutant load reduction before any environmental release.

How could coconut-husk fungi identified in a Hawaiʻi student lab move from bench tests toward practical cleanup of marine plastics and sunscreen?

Three conditional paths stand out. First, standardized characterization: university partners and student researchers could fully sequence and deposit the unmatched isolates, then publish degradation kinetics for defined plastics and UV filters—obstacle: taxonomic and safety review time; test: peer-reviewed rates and public accession numbers. Second, contained treatment of captured waste: coastal programs that already collect microplastics might inoculate coconut-filter residues in closed bioreactors rather than ocean release—obstacle: residual chemistry and permitting; test: verified mass balance and non-toxic effluent in pilot batches. Third, fiber–fungi co-design: materials scientists and community weavers could optimize husk porosity and tannin content to favor degrader growth while retaining filter strength—obstacle: supply consistency; test: side-by-side capture efficiency and biodegradation scores against baseline husks.

None of these is underway solely because of the fair win; each would need new funding, ethics review, and independent replication.
