Baguio Students Discover Alternative Biofuel Source from Taro (Gabi)
In 2016, six students from Saint Louis University (SLU) in Baguio City have discovered a cleaner, eco-friendly alternative to petroleum that can power vehicles, derived from taro, locally known as gabi.
The student researchers are Joji Takeoka, John Cyril Paco, Gregory Jones Ochoada, John Paul Galong, and Keanu Verzosa. Their invention, called โBIO-GABโ (from โBiofuelโ and Gabi), won the Business and Idea Development Award (BIDA) from the Philippine Chamber of Commerce last October.
Taro (Colocasia esculenta) is abundant in the Philippines, resilient to floods and drought, and grows in various soil types. According to the team, the cropโs high carbohydrate and glucose content makes it an excellent source of bioethanol, a renewable fuel.
The process took two weeks of fermenting taro oil, followed by extraction and refinement until it became efficient enough to fuel engines. The students tested BIO-GAB on a spare engine similar to those used in jeepneys, and results showed it was just as effective as petroleum-based fuels.
โWild taro is abundant yet inedible, but itโs rich in carbohydrates and glucose needed to produce bioethanol. We tested it in a spare engine to avoid risks, and it worked. The testing center even confirmed it is feasible for engines,โ explained researcher Gregory Jones Ochoada in an interview with Rappler.
The breakthrough highlights the potential of using locally available, sustainable crops as an energy source, an innovation that could help reduce dependence on fossil fuels while addressing environmental concerns.
