ME1D01 group presentation _ 3rd

  1. 1. ME1D01 Engineering and Environmental Management Case study presentation 12119472D IP Ka Yan Alberta 13085288D Choi Wing Lam 12101937D Yuen Hoi Ying Winnie
  2. 2. Outline 1) Present manipulate solid waste (MSW) treatment 2) Pros and Cons of the policies 3) Solution in developing the incineration program 4) Comparison and Contrast of MSW policies 5) Alternative treatment 6) Conclusion
  3. 3. Present Policies  Disposed in landfill(52%) ->West New Territories Landfill at Tuen Mun ->North East New Territories Landfill at Tai Kwu Ling ->South East New Territories Landfill at Tseung Kwan O Source from: http://www.cleanbiz.asia/image/hong- kong-landfill
  4. 4. Present Policies  Collection points are located in stores and railway stations ->Rechargeable batteries ->Waste of Electrical and Electronic Equipment (WEEE) ->Paper, aluminum and plastic bottle  Hong Kong Awards for Environment Excellent(HKAEE) ->Encourage businesses and organizations to adopt green management and green innovations Source from: http://www.hkaee.org.hk/eindex.html, https://www.wastereduction.gov.hk/chi/workplace/rechargebattery_detail.htm, http://edwinor.blogspot.hk/2011/06/blog-post_17.html
  5. 5. Present Policies  The Programme on Source Separation of Domestic Waste(2005) ->Take it more convenient for residents to separate waste at source ->Provide waste separation facilities on each building floor Source from: http://www.gov.hk/en/residents/environment/waste/wa steredrecyc.htm
  6. 6. Advantages of incineration Create jet fuel -using heat to generate electricity -combining components Environmentally Friendly -comparing with land fill only Source from: http://www.solarfeeds.com/jetfuel-will- replace-petroleum/
  7. 7. Disadvantages of incineration Costly -HK$8 billion Air Pollution -fly ash contains over 98% of dioxins produced -at least 300 tonnes of toxic ash per day Source from: http://environment.nationalgeographic.com/environment/global- warming/pollution-overview/
  8. 8. Disadvantages of incineration Damage wildlife and fisheries -snake, lizard and butterfly live there Higher rates of infant moralities -related to air pollution Toxins escaping into coastal waters over time Source from: http://www.edp24.co.uk/polopoly_fs/ib_1_proposed_incinerato r_site_king_s_lynn_saddlebow_1_2210295! image/1631260836.jpg_gen/derivatives/landscape_630/1631260 836.jpg
  9. 9. Solutions in development  Cost issue: energy generation e.g. electricity - Netherlands supply 5% of the country’s energy requirements - Germany provide 5-10% of current demands - Japan provide free hot water, free use of swimming pools, etc. (Hester, 1994)  Regulation on emission (CAA in USA ) - Monitoring - Government enforcement
  10. 10. Solutions in development  Air pollution control equipment - particulates, gases (EPA, 2005)  pre-process before incinerate (Sutco, 2010) Source from: http://www.sutco.de/fileadmin/datenblaetter/Anlageblaet ter_VSA_ENGL_02SEP2010.pdf
  11. 11. Compare and Contrast Hong Kong - 3 active landfills – expected to be saturated by 2018 - 300 active waste collectors, 30 involved in waste recycling and reprocessing operations (Liu, 2012) Singapore - 4 incinerator, 2 are Waste-to-energy incineration - Offshore sanitary landfill - Packaging Agreement - Uniform fee for waste collection (NEA, 2014)
  12. 12. Compare and Contrast Taipei - 3 incinerators - 1 sanitary landfill - Trash Per-bag Fee Collection policy - Recycling kitchen waste (Department of Environmental Protection, 2014), (Liu, 2012) Source from: http://www.no-burn.org/community-action-propels-the-taiwanese-government-towards-zero-waste
  13. 13. Compare and Contrast San Francisco, USA -Mandatory Recycling and Composting Ordinance -Waste related ordinances - Green Building Ordinance - Construction and Demolition Debris Recovery Ordinance - Food Service Waste Reduction Ordinance - Plastic Bag Reduction Ordinance (San Francisco Department of the Environment, 2014)
  14. 14. Compare and Contrast Hong Kong - Ways for waste disposal - Lack initiative in source reduction Other countries - Source reduction - Recycling and composting
  15. 15. Alternatives • MSW charging policy - Polluter-pays principle - Example: Taiwan Reduced waste disposal by 60% over 5-6 years • Hong Kong: consulting but some objection… Waste Prevention (Source Reduction) Source from: http://d2watasia.pixnet.net/blog/post/23454301-%E5%8F %B0%E5%8C %97%E5%B8%82%E5%B0%88%E7%94%A8%E5%9E %83%E5%9C%BE%E8%A2%8B%E4%B9%8B%E6%9C%9F %E8%A8%B1%E8%88%87%E6%AA%A2%E8%A8%8E
  16. 16. Alternatives • Legislation on package of products - Neighbourhood and Workers Services Centre - packaging waste from the manufacturers Waste Prevention (Source Reduction) Europe AmericaSource from: http://www.nwsc.org.hk/content.php?id=203
  17. 17. Alternatives Waste Prevention (Source Reduction) A laundry detergent flexible pouch weighs 85 percent less than a plastic bottle. The amount of packaging is 84 percent less. Source from: http://www.flexpack.org/public/source_reduction_examples.asp
  18. 18. Alternatives Reuse and Recycle • Barter - system of exchange by which goods or services are directly exchanged for other goods or services without using a medium of exchange, such as money. (O'Sullivan, Arthur; Steven M. Sheffrin, 2003)
  19. 19. Alternatives Reuse and Recycle Source from: http://www.fringebacker.com/zh-tw/blog/JupYeah_VeryHK/ Potential barter websites: Tradeduck.com, JUPYEAH 執嘢
  20. 20. Alternatives Reuse and Recycle • Provide subsidies or sites for holding a barter fair (incur expenditure but without any revenue if free entry) • Cooperate with NGO or barter websites to hold the official barter fair annually  encourage people reuse the things that needed  cultivate the reusing habit or trend
  21. 21. Alternatives Composting • Redeveloping farming industry - over 80% of agricultural land are abandoned (~3,800 hectares (Yiu, 2014)) - food residues recycling center - produce organic fertilizers for farming  raise the agricultural self-sufficiency rate
