Waste
Management Hierarchy
·
avoidance and minimisation, i.e. not
generating waste through changing or improving practices and design;
·
reuse of materials, thus avoiding disposal
(generally with only limited reprocessing);
·
recovery and recycling, this avoiding
disposal (although reprocessing may be required); and
·
treatment and disposal, according to
relevant laws, guidelines and good practice.
Storage,
Collection and Transport of Waste
·
handle and store wastes in a manner which
ensures that they are held securely without loss or leakage, thereby minimising
the potential for pollution.
·
use waste haulers authorised or licensed to
collect specific category of waste;
·
remove wastes on a daily basis;
·
maintain and clean waste storage areas
daily;
·
minimise windblown litter and dust during
transportation by either covering trucks or transporting wastes in enclosed
containers;
·
obtain the necessary waste disposal permits
from the appropriate authorities if they are required, in accordance with Waste
Disposal Ordinance (Cap 354), Waste Disposal (Chemical Waste) (General)
Regulation (Cap 354), the Land (Miscellaneous Provisions) Ordinance (Cap 28);
·
Dispose of the waste at licensed waste
disposal facilities
·
Develop procedures such as ticketing system to facilities tracking
of loads, particularly for chemical waste, and to ensure that illegal disposal
of wastes does not occur, and
·
Maintain records of the quantities of wastes generated,
recycled and disposal.
Excavated/Imported Filling Material
Dust:
·
wetting the surface of the stockpiled soil
with water when necessary especially during the dry season;
·
covering the stockpiled soil with sheets;
·
minimising disturbance of the stockpiled
soil; and
·
enclosure of stockpiling area.
Water
Quality:
·
installation of silt traps for the surface
water drainage system; and
·
covering stockpiled material with tarpaulin
during heavy rainstorm.
·
dropping heights for those materials should
be controlled to a practical height to minimise the fugitive dust arising from
unloading;
·
materials should not be loaded to a level
higher than the side and tail boards, and should be dampened or covered before
transport.
·
the travelling speed should be reduced to
10 km hr-1 to reduce dust dispersion and re-suspension from the operating haul
trucks;
·
wheel washing facilities should also be
installed and sued by all vehicles leaving the project area.
Construction & Demolition Materials
·
Careful design, planning and good
site management can minimize over-ordering and generation of waste materials
such as concrete, mortars and cement grouts.
The design of formwork should maximize the use of standard wooden panels
so that high reuse levels can be achieved.
Alternatives such as steel formwork of plastic facing should be
considered to increase the potential for reuse.
·
The Contractor should recycle as much
of the C&D material as possible on-site.
Proper segregation of wastes on site will increase the feasibility of
certain components of the waste stream by the recycling contractors.
·
Government has established a charging scheme for the disposal
of waste to landfill. This will provide
additional incentives to reduce the volume of waste generated and to ensure
proper segregation of wastes to allow free disposal of inert material to public
filling areas.
Chemical Waste
·

holding, resistant to corrosion, maintained in a good condition, and securely
closed:

capacity to accommodate 110% of the volume of the largest container or 20% by
volume of the chemical waste stored in that area whichever is the greatest;
·
have adequate ventilation;
·

(water collected within the bund must be tested and disposed as chemical waste
if necessary); and
·
