NUS Research Team Develops Greener Techniques for Biodiesel Production

National University of Singapore (NUS) researchers developed a set of environment-friendly techniques to produce biodiesel from waste grease more cheaply and efficiently.

Usually, waste grease is unsuitable for biodiesel production since catalysts could not process the waste grease in a single step. The NUS team led by Associate Professor Li Zhi developed an innovative one-step approach with a specially-engineered high-performance catalyst.

Aside from achieving impressive biodiesel conversion yields under optimal conditions, they can be easily separated from the biodiesel mixture at the end of the process for multiple reuses with little deterioration in performance.
