A teenager's innovative project using soy-based biodiesel secured first place in the 2025 Soybean Science Challenge at the Arkansas State Science and Engineering Fair, held April 4 at the University of Central Arkansas.
Vishak Meenachi, a 14-year-old freshman at Little Rock Central High School, impressed judges with his project titled “Environmental Sustainability of Soybean Derived Biodiesel compared to Standard Diesel.”
Meenachi research not only earned top honors in the Soybean Science Challenge, but also secured multiple awards, including second place in the Energy and Transportation Division at the Central Arkansas Regional Science and Engineering Fair, first place in chemistry at the state level, and the U.S. Naval Science Excellence Award.
“I am extremely honored to be the 2025 Soybean Science Challenge first place winner,” Meenachi said. “The opportunity to showcase my project on a state level is a thrilling experience and I am honored to be a part of it.”
Meenachi tested soy-based fuel on a 196cc, 3.5 horsepower diesel engine, which he plans to install in a custom-built go-kart. Meenachi received a $1,000 cash prize, and his teacher, April Owen, was awarded $300 as the top Teacher-Mentor.
Launched in 2014, the Soybean Science Challenge encourages high schoolers to explore how soybeans can contribute to global sustainability. Participants must complete an educational course before submitting research at fairs tied to the International Science and Engineering Fair (ISEF).
Bennet Chen, 16, also from Little Rock Central High, claimed second place in the state challenge for his project, “SoyCast,” which uses AI to forecast soybean yields. He received $500 and additional accolades, including an ISEF finalist spot. His teacher, Lee Conrad, received $200.
Winners from regional competitions included Bianca Navarro and Nora Medlock of Hot Springs, who earned $400 for research on increasing soybean salt tolerance. Other honorees across the state explored topics like soil pH, soy oil treatment, and soybean space growth.
“Soybean Science Challenge student researchers learn about this important commodity crop and its many uses, including feeding the world, development of biofuels and sustainable products,” said Julie Robinson, director of the Soybean Science Challenge. “It helps students develop an understanding of the challenges and complexities of modern farming.”
Former board member Gary Sitzer added, “The program also rewards scientific inquiry and discovery that supports the Arkansas Soybean Industry.”
