NCKU transnational research team converts waste cooking oils to biodiesel

Tainan, Taiwan, October 31, 2013

Prof. (Emeritus) Aharon Gedanken from the Department of Chemistry at Bar-Ilan University, Ramat-Gan, Israel, who is currently a Visiting Chair Professor (since Feb. 2012) at National Cheng Kung University (NCKU), southern Taiwan, has developed a microwave-based process that transforms waste cooking oils into biodiesel in 10 seconds, the university reveals.

At a press conference hosted by the Department of Materials Science and Engineering (MSE), NCKU, October 31, Prof. Gedanken has explained the idea of converting the biomass to biofuels.

“I was told that Taiwanese people like to cook a lot and the waste cooked oils can be a problem for the environment. So we come up with an idea that is very unique to combine the microwave and with certain catalyst that we can fully convert the waste cooked oils into the biodiesel in 10 seconds.”

The technology underlying the study is now in the process of applying for a patent, according to MSE Distinguished Professor Jiunn-Der Liao who has invited Gedanken to cooperate with NCKU faculty conducting the research.

“By the year 2020, in the European community, 20% of the diesel in the gasoline station will contain biodiesel,” said Gedanken, “and I hope by that year in Taiwan 100% will go to biodiesel and if the project is successful, we can convince people to collect waste cooked oils instead of through it away.”

This is exactly the project that we’d like to build here in NCKU, said Gedanken, and now we can covert 100 kilos a day and expectedly in the future tons of cooked oils can be converted into biodiesel.

“Actually everyone can do it on small scale at home kitchen with the domestic microwave,” Gedanken noted.

He also said, to do the reaction, you use a container and put in half cooked oil and in the end you get three layers – biodiesel, SrO, and glycerol. And in between we have SrO, the catalyst, which can be removed to carry out at least 10 more times the same reaction.

We believe we can convince the industry to build on a larger scale that we can convert all the cooked oils into biodiesel. It is hope this will be the replacement for fossil oil in the future, according to Gedanken.

This project supported and conducted by NCKU kicks off in August, according to Liao, “We hope that the budget for 2014 will be approved and then we’ll purchase the machine that will be able to run the cooked oils through the microwave which will be modified into a system to be able to run large quantity.”

“Prof. Gedanken has been named as one of ISI's Highly Cited Researchers and his study has been cited in more than 14,000 scientific articles. We’re honored to invite him over to conduct the research project as Visiting Chair Professor,” said Liao.
