For its Welcome Day, Nanyang Business School wanted to promote environment sustainability and at the same time, display the NBS logo impactfully. So it built a metal cage measuring 1.8m high, 1.8m wide and 5.4m long and packed 5,300 used plastic bottles inside it. The NBS letters were prominently displayed at an angle before the newly admitted students at the Nanyang Auditorium on 8 Aug 2018.
