A research team at National Taiwan University has developed a compact biodiesel production system small enough to fit inside a backpack, marking a step forward in portable and decentralised fuel generation, Rti reported.
The project, led by Associate Professor Chiang Ya-Yu, introduces a new “spiral coil separation technology,” which has been featured on the cover of the international journal Green Chemistry. The system is designed to simplify biodiesel production, which traditionally requires large equipment, high water usage, and lengthy processing times.
Researchers said the new setup uses a microreactor along with a specially designed spiral coil separator to streamline the process. This allows biodiesel to be produced in a much smaller space while maintaining efficiency. The system has achieved a yield of up to 91.14%, producing fuel that meets quality standards.
Doctoral researcher Yang Cheng-you said the system is designed for easy, local use, comparing it to a coffee machine in terms of convenience. He said such units could be deployed in small setups to convert waste cooking oil or vegetable oil into biodiesel for powering generators.
The team is currently working with CPC Corporation to explore commercial use of the technology.
Researchers said the development could help improve energy security, particularly in regions where disruptions can affect fuel supply. By enabling small-scale production, the system could reduce dependence on large fuel plants and allow fuel generation closer to where it is needed.
