A student innovator from Chanzeywe Technical and Vocational College has invented cooking technology that converts waste oil into a cleaner and more affordable energy source. The invention was unveiled during Madaraka Day celebrations.

Derick Toloyi said the idea was born early this year after he observed the careless disposal of used oil in garages, a practice he noted contributes to environmental pollution.

Interviewed, Toloyi said he carried out brainstorming and benchmarking at Mumias Sugar Company, which helped him refine the design of the jiko that now uses a solar-powered compressor to convert the smoky yellow flame from waste oil into a clean blue flame suitable for cooking.

He explained that the jiko is fitted with a regulator to control heat intensity and a tank reservoir that allows gradual use of stored oil, making cooking more efficient and affordable for households.

“Instead of throwing away used oil, let’s cook with it. This saves money, protects the environment, and creates jobs for youth who can fabricate and repair these jikos,” he said.

Toloyi noted that the innovation also contributes to reducing dependence on firewood and charcoal, thereby helping to curb deforestation and indoor air pollution. However, he acknowledged challenges in the design, including the need for electricity or solar power to run the compressor, as well as the importance of safety training to prevent flare-ups during operation.

Despite these challenges, he expressed optimism that the technology can be improved and scaled for wider use. He proposed the establishment of community workshops where youth can fabricate the jikos using scrap metal, while garages supply waste oil as raw material.

He further said his five-year vision is to see the jiko adopted in homes, schools and small businesses as a low-cost alternative cooking solution.

“Your talent is your capital. Don’t wait for jobs but create solutions. The world pays for skill, not just papers,” he added.

Vihiga Sub-County Deputy County Commissioner Linnet Orina commended the innovator and praised his creativity in turning waste into energy.

She encouraged other young people in the county to emulate Toloyi’s example and use their talents to develop practical solutions that benefit society.
