8 49 50 Semakau Landfill Recreational Activities • Only landfill in Singapore • Incorporated pollution control measures to minimise impact on marine ecosystem • Preserved ecosystem & biodiversity of Pulau Sport Fishing Bird Watching
Semakau Inter-tidal Walk Star Gazing • Opened up for recreational activities since July 2005 • Strike a balance between economic development and environmental protection
51 52 Short- term Outcome In the longer term…. • Lifespan of Semakau landfill • SGP 2012 - our environmental Estimated extension from 25 - 30 years blueprint for next 10 years to to 35 - 40 years help Singapore achieve • Need for new IP environmental sustainability • Target is 60% recycling rate by Estimated extension from 5 - 7 years to 2012 10 - 15 years
