The fifth International Engineering Invention & Innovation Exhibition (i-ENVEX 2014) in Kangar just wrapped up and the goal medalists beat out more than 87 entries with their project on the production of bio-products as a source of energy and waste water treatment.
The goal medalists are from the UCSI University chemical engineering and the students names are Jing Ren, Selvaraja, Chun Man and Shapnathayammal. The team, including Teoh Kai Wen developed an alternative fuel source that helps overcome fossil fuel dependence, and also reduces the pollution resulting from fossil fuel production. “It combines both the immobilization of cellulase enzyme (attachment of cellulase to a solid support) and functionalization (surface modification) of multi-wall carbon nanotube (MWCNT) processes,” Jing Ren explained. Jing Ren also said that: “The past few decades have seen cellulase enzyme being used as the catalyst in industrial processes but large quantities are often involved and the associated purchase cost for raw cellulase is very high”.
The raw material used in this project was palm oil sludge, which was usually disposed after palm oil production. The chemical engineers converted the waste into different products, “bio-oil” and “biochar” by processing the palm oil sludge with pyrolysis.
