Teenager Wins $75K Prize for Jute Sponge Removing Tyre Pollutants Bellevue 2026

Key Points

• Student Innovation: Lakshmi Agrawal, an 18-year-old high school student from Bellevue, Washington, developed a biodegradable hydro-sponge made from discarded jute plant waste.
• Pollutant Target: The sponge targets 6PPD-quinone, a toxic chemical produced when tire-preservative 6PPD reacts with atmospheric ozone and washes into waterways via stormwater.
• Laboratory Success: Lab testing demonstrated that the jute sponge removes up to 80% of 6PPD-quinone from water contaminated with tyre particles, alongside heavy metals and other particulate matter.
• Cost and Energy Efficiency: According to findings released by the Society for Science, the production of this nanocellulose hydro-sponge requires 85% less energy and lowers manufacturing costs by approximately 98% compared with conventional synthetic filtration media.
• Major Scientific Honour: Agrawal was awarded the $75,000 Regeneron Young Scientist Award at the 2026 Regeneron International Science and Engineering Fair (ISEF), competing against more than 1,700 student researchers from over 64 countries, regions, and territories.

Bellevue (Evening Washington News ) July 30, 2026 — An 18-year-old student from Interlake High School in Bellevue, Washington, has won a major international science award for inventing a sustainable, low-cost solution to a persistent aquatic environmental hazard. As reported by the TOI Science Desk of The Times of India, Lakshmi Agrawal earned the $75,000 Regeneron Young Scientist Award at the 2026 Regeneron International Science and Engineering Fair (ISEF) after creating a biodegradable hydro-sponge composed of agricultural jute waste. The material removes up to 80% of 6PPD-quinone—a toxic derivative of vehicle tyres that causes widespread mortality in spawning coho salmon populations—from urban runoff under laboratory conditions.

How Did an 18-Year-Old Student Develop a Solution for Tyre Pollution Killing Salmon?

How does an agricultural waste product transform into an advanced stormwater filtration system? According to official competition documentation published by the Society for Science, Agrawal addressed the challenge of 6PPD-quinone pollution by processing discarded jute fibres into nanocellulose hydro-sponges.

The chemical compound 6PPD is routinely added to motor vehicle tyres as an anti-degradant preservative to prevent rubber breakdown from ozone exposure.

However, as tyres wear down on roads, 6PPD reacts with ground-level ozone to form 6PPD-quinone. During precipitation events, stormwater washes these toxic particles off road surfaces directly into surrounding streams and river basins.

As reported by the TOI Science Desk of The Times of India, adult coho salmon returning to urban streams in the Puget Sound region of Washington state face catastrophic mortality rates, with up to 80% dying before spawning due to exposure to this specific compound.

Agrawal’s biodegradable sponge-like filters capture the toxic molecule as water passes through, preventing it from reaching critical aquatic habitats.

What Were the Key Findings and Environmental Advantages of the Jute Hydro-Sponge?

As detailed in official statements by the Society for Science, controlled laboratory evaluations using water tainted with tyre runoff confirmed that Agrawal’s invention removed up to 80% of dissolved 6PPD-quinone.

Beyond tyre pollutants, experimental results demonstrated that the nanocellulose matrix effectively traps additional urban stream contaminants, including toxic heavy metals and micro-particulates.

From an economic and environmental standpoint, the project offers notable improvements over synthetic filtration media.

As reported by the Society for Science, manufacturing the jute-waste sponge consumes 85% less energy than standard filtration technologies and reduces production expenditures by approximately 98%.

Because the primary substrate consists of agricultural jute waste, the filter naturally decomposes at the end of its operational lifecycle, preventing secondary microplastic pollution.

How Was Lakshmi Agrawal Recognised at the 2026 Regeneron ISEF Competition?

Where does this achievement fit within the global landscape of pre-college scientific research? As published in official announcements by Regeneron Pharmaceuticals Inc. and the Society for Science, the 2026 Regeneron International Science and Engineering Fair featured over 1,700 high school researchers representing more than 64 countries, regions, and territories, competing for more than $7 million in total awards.

Agrawal received one of the event’s top honours, the $75,000 Regeneron Young Scientist Award, alongside co-winner Nikola Veselinov of Sofia, Bulgaria.

Competition judges highlighted Agrawal’s ability to turn an economical, discarded crop residue into a scalable, high-performing environmental technology designed for roadside ditches and municipal stormwater management systems.

Background of the Development

The ecological impact of 6PPD-quinone was first publicly identified by researchers at the University of Washington Tacoma and Washington State University in late 2020.

For decades, fishery biologists in the Pacific Northwest had observed mystery die-offs of returning adult coho salmon in urbanised streams following rainstorms—a phenomenon referred to as Urban Runoff Mortality Syndrome.

Subsequent studies confirmed that 6PPD, an ozone-protecting chemical used by all major global tyre manufacturers, reacts with air molecules to create 6PPD-quinone, which is acutely toxic to coho salmon even at tiny concentrations measured in parts per trillion.

While state regulatory agencies and municipal authorities have searched for solutions, standard bio-swales and sand filters often lack the molecular trapping mechanisms required to extract dissolved chemical compounds efficiently before stormwater enters river basins.

Predictions for How This Development Can Affect Environmental Agencies, Municipalities, and Coastal Communities

This innovation stands to influence several groups across environmental management, local governance, and coastal commerce:

• Municipal Stormwater Engineers and Local Councils: If field-testing confirms the laboratory performance, municipal public works departments could integrate jute-based hydro-sponges into roadside catch basins, retention ponds, and urban drainage networks. With production costs reduced by roughly 98% compared with conventional synthetic filters, resource-constrained municipal councils could implement widespread stormwater filtration without exceeding infrastructure budgets.
• Environmental Protection Agencies and Wildlife Conservationists: Environmental regulators seeking to enforce stricter water quality standards around highway runoff could adopt Agrawal’s technology as a standardized Best Management Practice (BMP). Removing up to 80% of 6PPD-quinone and heavy metals prior to river discharge would accelerate wild salmon recovery programmes across northern coastal regions.
• Agricultural and Jute Processing Sectors: Widespread commercial adoption of nanocellulose sponges would convert low-value agricultural waste from jute-producing nations into a valuable secondary export, supporting circular economy practices in farming regions.
• Indigenous and Coastal Fishing Communities: Indigenous tribes and commercial salmon fisheries dependent on stable salmon runs in the Pacific Northwest could see long-term benefits in population stability, helping to preserve both cultural heritage and local maritime economies.
