Waste Reduction
In November 1998, the Government launched a 10-year
Waste Reduction Framework Plan. This was a response to the rapid
growth in the amount of waste being dumped in the landfills, leading
to a significant reduction in their expected lifespan. Given the
shortage of land in Hong Kong and the keen competition for any available
space, it will be difficult to find sites for any new landfills.
The plan aims to reduce the amount of waste produced, to encourage
re-use and recycling, to promote greater efficiency and economy
in the management of waste, and to prolong the usable life of Hong
Kong's landfills.
Waste recovery continues to play an important
role in waste management, resulting in the export of substantial
quantities of recovered waste materials for re-manufacturing outside
Hong Kong. In all, about 2.1 million tonnes of waste materials —
including paper, metals and plastic — were exported in 2004,
generating export earnings of about $3.4 billion.
Waste reduction and recovery have been the Government's
main focus in tackling the waste problem. The Government introduced
a package of initiatives in 2001 to further promote waste prevention
and recycling and has been making progress in this regard.
Charging for waste disposal is an important element
in the waste management strategy adopted in Hong Kong. It can provide
economic incentives for waste producers to reduce waste and to carry
out sorting to facilitate re-use and recycling which will, in turn,
help conserve landfill capacity. As a first step, the Government
intends to levy charges for the disposal of construction waste at
landfills, sorting facilities and public fill reception facilities.
In late 2003, it introduced the Waste Disposal (Amendment) (No.
2) Bill to give effect to the scheme for charging for construction
waste disposal. The Bill was passed by the Legislative Council in
July 2004. Related regulations will be implemented in 2005.
Landfills
All municipal solid waste is disposed of at three
large modern landfills in the New Territories. Specialist waste
management contractors operate these landfills to high environmental
standards.
The community disposed of about 9 290 tonnes
of municipal solid wastes every day in 2004. Of this, 7 020
tonnes was domestic waste and 2 270 tonnes were commercial
and industrial waste. On average, each person in Hong Kong disposed
of about 1.36 kilograms of municipal solid waste daily.
Rapid development in Hong Kong over the past decade
has contributed to a dramatic increase in the amount of construction
and demolition (C&D) material. The material generated every
day amounted to some 56 000 tonnes, on average, and about 88 per
cent of it was suitable for re-use in reclamation projects.
The current three landfills have a remaining lifespan
of only 6 to 10 years. In 2004, the Government kicked off a public
communication programme on the urgent need to extend the existing
landfills. Planning and development work on possible landfill extension
schemes will soon proceed to ensure the continuity of waste disposal
outlets.
Hong Kong has 13 old landfills. For safety and
environmental reasons, restoration measures have been taken at these
landfills, and restoration of 12 of them has been completed. It
is intended to restore the last landfill, at Pillar Point Valley,
by mid-2006. After full restoration, the sites may be used primarily
for community and recreational activities.
Refuse Transfer Stations
The network of refuse transfer stations forms
an important component of the Government's waste disposal facilities.
Waste collected in urban centres is delivered to these stations,
where it is compacted into sealed containers for delivery to the
three landfills.
Seven modern transfer stations and one set of
Outlying Island Transfer Facilities (OITF) handle 5 360 tonnes of
waste every day. This is mostly domestic waste, and represents around
76 per cent of Hong Kong's total daily domestic waste production.
Six of these transfer facilities — the stations at Hong Kong
Island East, Hong Kong Island West, West Kowloon, North Lantau and
North-West New Territories and the OITF on Ma Wan — also provide
services to private waste collectors.
Chemical and Special Wastes
The widespread malpractice of dumping chemical
waste into sewers and surface waters was stopped by the introduction
of comprehensive controls on the handling and disposal of chemical
waste. All chemical waste producers are required to properly pack,
label and store their chemical wastes before disposal at proper
treatment facilities. A trip ticket system — involving the
waste producers, licensed collectors and licensed disposal points
— tracks the movement of chemical waste from its origin to
the final disposal point.
In 2004, a daily average of 107 tonnes of chemical
waste, including waste from sea-going vessels, was treated at the
Chemical Waste Treatment Centre on Tsing Yi Island, the main treatment
facility for chemical waste. A government contractor operates the
treatment centre. Waste producers using its services are required
to pay part of the treatment cost.
Clinical Waste
In recognition of the public health risks associated
with the improper handling of clinical waste generated by health-care
activities, the Government plans to implement legal controls on
the handling, collection and disposal of this type of waste. The
Government also proposes to modify the Chemical Waste Treatment
Centre so that it can receive clinical waste for proper treatment,
replacing the current practice of disposing of untreated clinical
waste at landfills. The health-care sectors and other related parties
have been consulted and have generally supported the proposal. A
Waste Disposal (Amendment) Bill, providing for the control of clinical
waste, is planned to be introduced into the Legislative Council
in 2005. Subject to the passage of the bill and related subsidiary
legislation, the Government intends to implement the controls in
2006.
Large-scale Waste Treatment Facilities
No matter how effective it is in dealing with
waste prevention and recycling, Hong Kong still has to deal with
a large volume of non-recyclable waste. New facilities to treat
waste and reduce its volume will have to be put in place. Such facilities
will need to meet the highest international environmental standards
and be cost-effective. In April 2002, the Government invited the
local and international waste management industries to express their
interest in proposing the latest technologies for the development
of large-scale waste treatment facilities in Hong Kong. An advisory
group, comprising mainly non-officials, is considering various waste
management technologies and options that are potentially suitable
to Hong Kong. The public will be consulted about the technology
options in 2005. However, even with such large-scale waste treatment
facilities, there are residual wastes that must be handled safely.
Hence, Hong Kong will continue to require landfills for the final
disposal of waste.
Import and Export of Waste
Controls on the import and export of waste under
the Waste Disposal Ordinance (WDO) ban the importation of hazardous
waste from developed countries (mainly of the Organisation for Economic
Cooperation and Development and the European Union). The controls
are in line with the Basel Convention on the Control of Transboundary
Movements of Hazardous Wastes and their Disposal.
The convention's main control mechanism requires
notification and consent by authorities of the states of origin,
destination and transit before the shipment of hazardous or non-recyclable
waste can begin.
In January 2000, a memorandum of understanding
was signed between the HKSAR and the Mainland to strengthen control
of hazardous waste movement between the two places.
Under the WDO, it is an offence to import or export
hazardous waste, regardless of its purpose, into or out of Hong
Kong without a permit. Maximum penalties are a fine of $200,000
and six months' imprisonment for the first offence, and a fine of
$500,000 and two years' imprisonment for subsequent offences. In
2004, there were 37 prosecutions for illegal import and export of
waste, with fines totaling $490,000. Most of these offences were
releated to trans-shipment of hazardous electronic waste through
Hong Kong to other countries in the Asia-Pacific Region. The EPD
has stepped up enforcement with both local and overseas control
authorities against these illegal activities since early 2004.
Floating Refuse in the Harbour
The Marine Department deploys a fleet of seven
government vessels and 75 contractors' vessels to collect floating
refuse and refuse from vessels. In 2004, 13 874 tonnes were
collected. The Government has also tackled the floating refuse problem
by raising public awareness through publicity and educational activities,
and deterring marine littering by means of enforcement.
Marine Dumping
Hong Kong's development projects continue to generate
vast quantities of dredged mud that is unsuitable for reclamation
or other uses (31.3 million cubic metres in 2004). It is dumped
at sea in specified mud disposal areas under a permit system. Regular
monitoring is undertaken by the Government to make sure that dumping
operations do not create an unacceptable impact on the marine environment.
Because of the serious potential impact of illegal dumping on the
marine environment, the EPD maintains strict control over dumping
operations under the Dumping at Sea Ordinance. These operations
follow the requirements of the London Convention on marine dumping.
Marine dumping permits allow operations to be
carried out only by a vessel equipped with an automatic self-monitoring
device. This device tracks all marine dumping operations by recording
the position and draught of the vessel, so that the authorities
can trace any illegal dumping in a cost-effective manner. Moreover,
the department's inspectors operate frequent patrols. There were
33 prosecutions for illegal dumping offences in 2004.
Monitoring and Investigation
The assessment of progress towards achieving policy
goals is one of the EPD's key activities. Its routine monitoring
and special investigations form the basis for much of the strategic
planning, provision of facilities and statutory controls aimed at
improving the environment. The department has 94 sampling stations
in the marine waters, including enclosed bays and typhoon shelters,
and another 82 stations for inland waters. It also keeps 41 bathing
beaches under surveillance.
The current water quality monitoring programme
provides a comprehensive record of the chemical, physical and microbiological
quality of Hong Kong's waters. The monitoring data is depicted in
the annual water quality reports available on the EPD's home page.
Information on the latest water quality of the major marine and
river stations is also published quarterly on the home page. As
the public are usually more interested in the latest water quality
grades of bathing beaches, such details are issued to the media
and updated on the department's website every week.
