Kyle King is the Director of Green School in Bali, an establishment that aims to “create a global community of learners, making our world sustainable.” In 2015, the students decided to tackle the carbon footprint generated by their school buses. With help from the teachers, they created a Bio Bus running on biodiesel made from used cooking oil. Following a successful pilot, Kyle and the students expanded the project, developing a social enterprise and learning centre. 

In 2020, 7 Bio Buses travelled thousands of kilometres every month, saving 14 tons of CO2 emission in total that year. This solution repurposes 500 litres of used cooking oil every month, which was previously sold on the black market or thrown in drains or waterways. Each week, the students (aka the Grease Police) collect the future fuel from hotels, restaurants and cafés, offering them a more environmentally friendly way to get rid of their used oil.  

Promoting biodiesel for greener mobility 

The success of the Bio Bus has helped to raise awareness in Indonesia about clean energy and, in particular, the health and environmental problems created by non-regulated use of used cooking oil – often used well beyond its sell-by date and mixed with other chemical products before being sold back to restaurants. The Bio Bus project has already been extended to 4 other Indonesian schools.
