ISEF · 2026
Environmental Engineering
Severe eutrophication causes hypoxic “dead zones” (e.g., the Gulf of Mexico). The mass death of marine life accelerates oxygen depletion, creating a vicious cycle. Conventional restoring met…
ISEF · 2026
Environmental Engineering
Accumulated litter in community spaces has a negative impact on local economies and aesthetic appeal. While autonomous cleaning solutions exist, most current market products, such as the Roo…
ISEF · 2026
Environmental Engineering
Deep-sea coral restoration efforts currently suffer from a 65% failure rate, primarily due to inefficient, delayed, and high-risk monitoring techniques. To address this, we developed DEEP (D…
ISEF · 2026

Nearly 30 farmers take their lives everyday in India due to immense socioeconomic pressure from their families. One prevalent factor to this stress is the low crop yield, often caused by dis…
ISEF · 2026
Environmental Engineering
Millions of people use squat toilets daily, yet urine splashing remains a common problem, soiling floors and clothing, promoting bacterial growth, and causing unpleasant odors. Beyond hygien…
ISEF · 2026
Environmental Engineering
While global oil production exceeds 100 million barrels per day, over 40 million liters of crude oil have contaminated marine ecosystems since 2020, resulting in catastrophic ecological and…
ISEF · 2026
