NCKU Transnational Research Team Turns Waste Cooking Oils to Biodiesel
TAINAN, Taiwan --(Business Wire)--
Prof. (Emeritus) Aharon Gedanken from the Department of Chemistry at
Bar-Ilan University, Ramat-Gan, Israel, who is currently a Visiting
Chair Professor 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.
He said, "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 catalyt 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
"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 kilograms 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
and recycled 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.
