6.13.1The
following quantities of waste are expected to arise during the construction of
the NLDFS developments and CKWLR:Dredged materials (approximately 54.55 M m3 and 4.2M
m3 respectively, maximum dredging rate is 90,600 m3 per
day and 6,000 m3 per day respectively), construction and demolition
waste (peak volume will be added); chemical waste (a few cubic metres per
month); and general refuse (3.9 tpd and 227.5 kg d-1 respectively
during peak construction period).No
surplus of excavated materials is envisaged.
6.13.2Reclamations
for the NLDFS development and CKWLR require large amount of fill materials and
therefore offers a very good opportunity to utilise the public fill generated
in the HK SAR.The use of public fill
will not only alleviate the demand for virgin fill material but also reduce the
pressure of disposing inert Construction and Demolition Material (C&DM) at
the strategic landfills.The intention
to maximise the use of good quality public filling material reclamations has
been incorporated into the engineering design of the Project whilst ensuring
that the programme is not adversely affected.Apart from Penny’s Bay Stage I, other reclamation will use over 70% of
public fill.These initiatives will
have indirect environmental benefit by utilisation of public filling material
to the greatest degree bearing in mind the programming constraints.
6.13.3Waste
arising during the operational phase in it’s full operation is estimated be at
least 324.53 tpd without any waste reduction or recycling. This actual quantity
is expected to increase significantly because waste generation from some
developments cannot be determined at this stage.With proper planning and management, it is considered that the
handling and disposal of waste arising from the Project will not cause
insurmountable impacts.
6.13.4According
to the assessment carried out for the Theme Park Phases I and II ([17]),the market driven recycling industry can
recycle 23-26 % of waste to be generated in the tourism related
developments.It is recommended that a
additional further target of an additional 10% for recyclable recovery
programme at these developments and potentially, an extra 10% for food waste
source separation (assuming that a composting facility for food waste planned
in the Waste Reduction Framework Plan is
available) programme be adopted in the Waste Management Plan of the tourism
related developments.
6.13.5According
to Table 6.6a and based on the waste
arisings from the NLDFS developments and associated facilities and market
driven recycling rate of 23-26 % for tourism related developments, the daily
waste arisings after market driven recycling in full operation is at least 227.23
to 236.44 tpd.The tourism related
development recommended recyclable recovery programme can further reduce waste
by and additional 10 %, which is 30.71 tpd. In addition, ifC1819 Rep: Northshore Lantau EIA - Waste SectionC1819 Rep: Northshore Lantau EIA - Waste Section
style="mso-spacerun: yes"> food waste composting facility is available
in HK SAR, an extra 10 % of waste (i.e. 30.71 tpd) to be generated from the
tourism related developments can be reduced.
6.13.6The
assessment indicates that the North Lantau Transfer Station will be able to
handle the waste arising from the NLDFS developments.
6.13.7Good waste
management practices have been recommended to ensure that adverse environmental
impacts from NLDFS developments and CKWLR construction and operational wastes
are prevented.This EIA concludes that
no unacceptable environmental impacts will result from the storage, handling,
collection, transport, and disposal of wastes arising from the construction and
operation of the NLDFS developments and CKWLR.
