Tyler ISD’s Advanced Animal Science/Livestock Production students at the Career & Technology Center (CTC) took sustainability to the next level by building their own anaerobic digesters in an interactive, hands-on activity. The project demonstrated how organic waste, such as manure and food waste, can be converted into renewable energy and valuable byproducts through anaerobic digestion.
Led by teacher Ashleigh Dickey, students created mini digesters using water bottles, manure, food waste (typically bananas), water, and balloons. The bottles were sealed with balloons to ensure an airtight environment and left in a warm location to encourage gas production. Over a couple of days, the balloons inflated with biogas, providing a visual representation of the process.
“This project gives students a real-world look at renewable energy and sustainability while also equipping them with skills for future careers,” Dickey said. “Not only do they learn how anaerobic digestion works, but they also gain hands-on experience that ties directly to the certification they’re working toward in animal science.”
Students enrolled in this class can earn the ELANCO Fundamentals of Animal Science certification, which offers a competitive edge in fields such as veterinary medicine, ranching, and zoology. The project highlights the innovative ways students are preparing for careers in animal science while exploring solutions to reduce methane emissions and dependence on fossil fuels.
