5 Solid Waste Challenges in Singapore i. Amount of waste generated in Singapore has risen rapidly & will continue to rise with population & economic growth ii Land will become increasingly more scarce Index Current Population: 5.6 mil GDP Population Waste Disposal 8,402 tons/day (2015) 1,200 tons/day (1970) Year At this rate of waste growth, we ll need to build But New waste-to-energy plant 7-10 years Semakau Landfill years New offshore landfill there will be less land available

6 Challenges in Singapore Hot & Humid Climate Area : sq km Population : 5.6 million Key Challenge : Scarcity of Land

7 2 3Rs Reduce, Reuse, Recycle 7

8 Why Reduce, Reuse & Recycle? Save Natural Resources Reduce Environmental Impact Semakau Landfill Prolong Lifespan of our Landfill 8

9 What can you do to practise Reduce, Reuse and Recycle? 9
