5. Present Policies
he Programme on Source
Separation of Domestic
Waste(2005)
ake it more convenient for
residents to separate waste
at source
rovide waste separation
facilities on each building

6. Advantages of incineration
Create jet fuel
-using heat to generate
electricity
-combining components
Environmentally
Friendly
-comparing with land fill

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

warming/pollution-overview/
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:

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. Solutions in development
Air pollution control equipment
- particulates, gases (EPA, 2005)
pre-process before incinerate (Sutco, 2010)

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)
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. Compare and Contrast
Hong Kong
- Ways for waste disposal
- Lack initiative in source reduction
Other countries
- Source reduction
- Recycling and composting
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…

• Legislation on package of products
- Neighbourhood and Workers Services Centre
- packaging waste from the manufacturers

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.

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)
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. 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
