Three students from Temasek Engineering School, Aldwin Su Duwen, Lina Hee Zhen Zhen, and Yip Yong Seng clinched a Commendation Award in the Greenwave Environmental Competition 2006.

Their invention, the "Paper Multiplier", converts used paper into hand towels, without going through the conventional paper recycling process of pulping.

The conversion is done by specially textured rollers that are geared to rotate in opposite directions. By turning the handle clockwise, a single sheet of A4 paper is passed between the rollers, making it wrinkled and perforated, and hence highly absorbent.

The competition was held on 12 Oct 2006, and the students received their prize ($500) at a ceremony on 30 Jan 2007.

All joy for the winning team
