Converting waste vegetable oil into a useful energy source

10.09.2002


A researcher in environmental engineering at Staffordshire University has developed a technique to convert unwanted cooking oil into a ‘biodiesel’ which is a much cleaner alternative to fossil diesel.



Dr Tarik Al-Shemmeri, a Reader in Environmental Engineering at Staffordshire University, uses discarded vegetable oil as the basis of his sustainable fuel which, when burnt, DOES NOT
give off sulphur dioxide, unlike conventional diesel.

Sulphur dioxide contributes to what has been dubbed ‘acid rain’ and is among the world’s worst polluting agents and is blamed for attacking buildings in big cities.



The biodiesel also finds a new use for the vast amounts of unwanted cooking oil endlessly produced by restaurants and hotels around the world. If not properly disposed off used cooking oil can pollute agriculture land and waterways.

Dr Al-Shemmeri explained: “Biodiesel is produced from vegetable oils in a process known as esterification. This process, which uses alcohol and gentle heating, converts vegetable oils into separate ‘esters’ or compounds such as biodiesel, glycerine and some traces of water.

“Each ester chain usually contains 18 carbon atoms and it retains two oxygen atoms; this gives the product its unique combustion qualities.”

Dr Al-Shemmeri believes one of the best applications for the biodiesel is to fuel small power generators which create heat and electricity for small and rural communities around the world.

“This fuel would be ideal for use in conventional diesel-powered generators which typically supply electricity to villages in parts of Africa or Asia. By collecting unwanted cooking oil villagers can access a reliable and cheap fuel."

Dr Al-Shemmeri has has been pleased with the results of experiments using the biodiesel in a 10 kilowatt diesel engine mounted on a test bed at his laboratory in the University’s School of Engineering and Advanced Technology.

He will present his findings this week to the 37th International Universities Power Engineering Conference (UPEC 2002). Energy experts from around the globe are attending this prestigious forum, representing 36 countries from five continents.

The three-day conference will be covering a range of subjects, including power generation, renewable energy sources, and ways to operate, control and protect power systems.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
