    Waste Reduction Program Waste Reduction Program Presentation Transcript

    • LAI, PO MAN (09410317) PUN, KONG CHAK (09428488 ) Waste Reduction Program Future trend on Hong Kong Landfills or Incineration
      • Introduction
      • Current Policies
      • Current Waste Management Programs
      • Recommendations
      • Conclusion
    • ! 13,503 tons/day ! How many disposal waste per Day?
    • !Solely treated by Landfills! How the solid waste be treated?
    • Policy Framework for the Management of Municipal Solid Waste
    • The Waste Collection Arrangement
    • Current Waste Management Programs Solid Waste Disposal at Landfills in 2001 to 2008
    • Current Waste Management Programs ?Does the waste reduction campaign success?
    • Details of Three Strategic Landfills ! ONE YEAR LEFT ! Operation Life $130 million/year $170 million/year $150 million/year Operation cost $1,100 million $2,600 million $2,200million Capital cost 30 years after completion of operation Aftercare period Special waste Special waste   Construction waste Construction waste Construction waste     Municipal waste Municipal waste Municipal waste Waste types ~2,200 tonnes per day ~5,300 tonnes per day ~6,580 tonnes per day Current waste intake 35 Mm³ 43 Mm³ 61 Mm³ Capacity 140m 100m 120m Max. depth of waste 240 mPD 135 mPD 170 mPD Max. height of filling 61 ha 100 ha 110ha Area June 1995 September 1994 November 1993 Commencement of operation Ta Kwu Ling, New Territories Tai Chik Sha, Tseung Kwan O Nim Wan, Tuen Mun Location North East New Territories (NENT) South East New Territories (SENT) West New Territories (WENT)
    • !We still produce huge quantities of solid waste everyday!
    • ! Explosion !
    • How can we reduce the volume of disposal waste? Incineration
    • ☆ Volume reduced ~90% Solid waste: 13,503 tons
    • Remarks: 1 & 2 – Data collected from Environmental Protection Department on 2008 Statistic. 3 – Expected performance of a typical advanced incinerator.
      • Extra works required to handle the non-combustible leftovers after incineration process
      • Consume huge area
      • Landfill areas cannot reuse in short period & topsoil required regular maintenance
      • Non-sustainable, require to find another new site upon it filled
      Disadvantages Other Than Pollution
      • Save cost
      • Decrease about 90% volume of solid waste
      • Energy is recovered for electricity generation
      • Advanced technology on eliminating pollutants
      • Handle more solid waste in a same time
      • Land reuse
      • Methane
      Advantages Air pollution: dioxin & ash Air pollution: methane Water pollution: leachate Soil pollution: decomposition of biodegradable waste Derived Pollution 250 million 490 million/year (2008) 1 Operation Cost 4 billion 6 billion Construction Cost 10 ha. 270 ha. Area of Land Used 3,000 tons/day 16,000 tons/day (2008) 1 Solid Waste Disposal Rate Incineration 2 Landfills
    • ☆ Less Disposal Waste ☆ Volume reduced by incinerator Share Disposal Waste Cost
    • Be environmental friendly, and save our planet!
    • ~The End~ ───── Thank You!
