Used Cooking Oil Converted Into Fuel For Vehicles


Raising concerns over global fuel price hikes have prompted USM students to explore fuel alternatives for vehicles.

Through the innovation of 23-year-old Wan Khairul Norhaizan Wan Ishak, the university found that used cooking oil could be converted into fuel for vehicles. And it’s environment-friendly!

"Biodiesel oil is safer and more economical compared to current energy sources. It’s also free of plumbum (technical name of lead) and in line with aims to reduce green house effect, as recommended by the Kyoto Protocol.

"More importantly, use cooking oil which many have been throwing away, could be recycled as an alternative source of energy for motor vehicles," she said, when met at the National Level Research and Innovation Competition 2008.

Wan Khairul Norhaizan is a final year student of the USM Chemical Engineering Research Centre.

Elaborating, she said the used cooking oil has to be separated first from other substance in it, before it is processed through a chemical reaction.

"Through this innovation, one litre of used cooking oil can produced one litre of biodiesel oil. This means the used cooking oil is used in full, without any wastage.

"Some vehicles may need to go through a modification before it can be used as biodiesel fuel. Nevertheless, now there are some vehicle producers such as Honda and Toyota which have introduced biodiesel vehicles. I believe biodiesel has the potential to replace fuel soon," she added.

She also said substance used in the modification process can be repeatedly used.

Apart from biodiesel fuel, this innovation has also successfully produced 'glycerin' – which is a common ingredient in the pharmaceutical industry in the world.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
