To commemorate Singapore’s 49th year of nation building and to promote recycling, Yeo’s put up a display of the nation’s public housing development. Hundreds of kindergarten children were involved in making 48 HDB blocks using Yeo’s tetrapaks. The 49th building was created by artist Akira Takahashi. The foundations of the blocks were made with polyal boards which were recycled from tetrapaks. The display, measuring 21m by 3.6m, was unveiled at Clarke Quay Central on 31 Jul 2014.
