1.0            Introduction

This Waste Management Plan (WMP) sets out in detail the approaches CRBC – KADEN JV should adopt in the management of waste generated from the various different construction activities. It also sets out the procedures for the waste management activities and requirements during the construction.


To demonstrate the Project Team’s commitment on the continual improvement of our waste management performance, the project waste management policy has been established as below:


2.0            Environmental Legislation and Standards

2.1              Statutory Requirements

The following legislation relates to the handling, treatment and disposal of wastes in Hong Kong, and should be observed with regard to all wastes generated and requiring disposal due to the construction, where applicable:


·        Waste Disposal Ordinance (Cap 354)

·        Waste Disposal (Chemical Waste) (General) Regulation (Cap 354)

·        Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap 354)

·        Land (Miscellaneous Provisions) Ordinance (Cap 28)

·        Public health and Municipal Services Ordinance (Cap 132) – Public Cleansing and Prevention of Nuisances (Urban Council) and (Regional Council) By-Laws


The Waste Disposal Ordinance (WDO) prohibits the unauthorized disposal of wastes. The illegal tipping or flytipping of wastes on unauthorized sites is also controlled under the WDO. Under the Waste Disposal (Construction Waste Disposal Charging Scheme) Regulation, project team should apply for a billing account from EPD for disposal of construction wastes generated from the project. The regulation prescribes the requirements of handling of construction wastes on site and the construction waste disposal-charging scheme.


Under the Waste Disposal (Chemical Waste) (General) Regulation all producers of chemical wastes (including asbestos) must register with EPD and treat their wastes either utilizing on-site plant licensed by EPD, or arranging for a licensed collector to take the wastes to a licensed facility. The regulation also prescribes the storage facilities to be provided on site, including labeling warning signs, and requires the preparation of written procedures and training to deal with emergencies such as spillages, leakages or accidents arising from the storage of chemical wastes.


Construction wastes that are wholly inert would be taken to public dumps. Public dumps usually form part of land reclamation schemes operated by the Civil Engineering and Development Department (CEDD). The Land (Miscellaneous Provisions) Ordinance requires that individuals or companies who deliver suitable construction wastes to public dumps obtain dumping licenses. CEDD issues the licenses under delegated powers from the Director of Lands.


The Public Cleansing and Prevention of Nuisances By-Laws provide further controls on the illegal tipping of wastes on unauthorized (unlicensed) sites.


The project team should obtain all necessary permits and licenses under these ordinances including, but not limited to:

·        Chemical waste permits/ licenses under the Waste Disposal Ordinance (Cap 354)

·        Billing Account for construction waste disposal-charging scheme (Cap 354)

2.2                   Non-statutory Requirements

5.0            Construction and Demolition Waste Management, Mitigation Measures and Protocols

5.1              Introduction

The purpose of this section is to describe the proposed mitigation measures considered to ensure that all wastes generated during the construction and demolition are well-managed on-site, transported and disposed of in a manner that is both environmentally acceptable and in full compliance with statutory and contractual requirements. A Site Layout Plan indicated the area for the waste management such as temporary storage area, waste sorting area and disposal area as presented in Appendix B.

5.2              Mitigation Measures

5.2.1     Avoidance / Minimization Measures

§  Design and programme excavation works so that the materials excavated can be re-used as back-fill material to balance cut and fill and hence reduce the generation of excavated materials.


§  Right amount of raw materials should be ordered at the right time with proper control and documentation on material flow to minimize over-ordering. Raw materials should be fully utilized to avoid wastage


§  Surplus materials should be returned to stock in centralized area with suitable protective measures. If possible, surplus materials should be exchange with other sites, to minimize material wastage


§  Careful design and planning and good site management should be maintained to minimize over ordering and generation of waste materials such as concrete, mortars and cement grouts


§  Sequence of demolition should be planned to allow the separation and sorting of building materials.


§  Avoid, reduce or minimize the use of timber in temporary works construction as far

§  as possible. Procedures of using timber should be established guiding the use of timber on site, in order to reduce or minimize the use of timber. The design of formwork should maximize the use of standard wooden panels so that high level of reuse can be achieved


§  Steel false work should be used as much as possible to reduce the amount of waste timber generated from the project

§  Current operation procedures including any waste reduction measures should be reviewed, especially during installation and cutting, to avoid unnecessary use

§  Broken items or offcuts should be used when sections of small lengths are required

5.2.2    Reuse and Recycle

§  If cut and fill could not be balanced on-site, suitable excavated materials should be sorted on site to recover the inert portions (e.g. soil and broken rock) for reuse on site before the remaining materials are disposed off site or disposal to designated Public Filling Facility


§  Carefully plan/program excavation and backfilling activities so that excavated materials can be used for backfilling within the site


§  Excavated material should be reused as close to the point of excavation and as soon after excavation as possible and directly transferred to the area of deposition, if practicable.


§  The inert C&D materials generated from the toll plaza cut slopes will be used for construction of the raised platform for the toll plaza where possible.


§  All C&D materials arising from or in connection with demolition work should be sorted on-site and be separated into different groups for disposal at landfills, public filling facilities or recycling appropriate


§  Identify and list out all work processes or activities that should generate reusable/ recyclable materials during construction and demolition


§  For those suitable inert C&D materials (e.g. broken concrete from demolition or road improvement works) should be properly sorted for recycling into aggregates and recover the materials for on -site usage


§  Demolition debris from demolition works should be sorted to recover on site broken concrete, reinforcement bars, mechanical and electrical fittings as well as other building services fittings / materials that have established recycling outlets


§  Procedures of the handling of reusable/ recyclable materials should be established


§  Recycle suitable C&D materials by transporting the materials to designated C&D materials recycling facilities for processing


§  All materials should be reused on site as far as practicable, including formwork plywood, hoardings, scaffolding, trench supports, topsoil and excavated materials.


§  Where necessary, alternatives such as metal scaffolding, steel formwork or plastic facing should be considered to increase the potential for reuse.


§  Suitable materials, such as metal should be recovered on site for collection by recycling contractors


§  All cardboard and paper packaging (for plant, equipment and materials) should be recovered on site, properly stockpiled in dry condition and covered to prevent cross contamination by other C&D materials


§  Reputable recycling contractors with valid licenses and fulfilling all the legislative requirements should be employed to facilitate that recyclable materials sorted from the site are collected with reasonable care


§  The quantities of all the recyclable materials should be recorded before removal off site

5.2.3    Storage

The materials stockpiled on-site should be managed in order to prevent any potential impacts. Following measures should be considered in order to properly manage the stockpiled materials:


§  Identify and provide sufficient space for temporary storage of C&D materials to facilitate collection and/ or sorting on site


§  Stockpiled materials should be sited away from any stream courses so as to avoid releasing materials into the water bodies


§  Demolished debris should not be accumulated on the floors unless the debris accumulation is justified by engineering calculations


§  No stockpile of construction materials, debris, formworks, or other forms of obstructions is allowed to block the accesses throughout the entire construction period


§  Location to minimize visual impacts and nuisance related to noise and air quality (dust) to any sensitive receivers


§   Storage of material on site should be kept to a minimum to avoid nuisance to local residents


§   Keeping the movement of stockpiled material to a minimum


§   Stockpiled materials should be covered by tarpaulins and/or watered as appropriate to prevent windblown dust and/or surface run-off.


§   Measures such as providing sand bag barriers should be provided to prevent the washing away of construction materials, soil, silt or debris into any drainage system. Any washout of construction or excavated materials should be diverted to the drainage system via sediment traps

5.2.4    Disposal Methods

§  All surplus excavated material generated from the project should be disposed of at the designated Public Filling Facility


§  According to the Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap. 354N), Construction Waste Disposal Charging Scheme mentioned in Section 5.10 in this WMP should be implemented during the construction.


§  The acceptance criteria for Public Filling Facility and Landfill should be followed


§  All inert C&D materials generated from this contract should be disposed of at the designated Public Filling Facility. Such materials should be free from marine mud, household refuse, plastic, metal, industrial and chemical waste, animal and vegetable matter and other matter considered unsuitable by Filling Supervisor


§  All dump trucks used for delivery of public fill to public filling facilities should have valid Dumping Licenses issued by CEDD. The inert C&D materials delivered to the public filling facilities should be in accordance with the conditions in the dumping license


§  All non-inert portions of C&D material (C&D waste) generated from the project should be disposed of at the designated landfill and/ or other disposal outlet as directed by the Engineer. Should provide EPD with one week’s advance notice before starting to deliver the C&D waste to the landfills and should inform EPD of any subsequent changes to the disposal programme during the contract period


§  Trees and vegetation should be stripped prior to site clearance, chopped and compacted using suitable mobile compactors to reduce the volume of material to be transported and disposed of


§  Should not permit any sewage, wastewater or effluent containing sand, cement, silt or any other suspended or dissolved material to flow from the site onto any adjoining land or allow any waste matter or refuse which is not part of the final product from waste processing plants to be deposited anywhere within the site or onto any adjoining land


§  In order to minimize the impacts of demolition works, the wastes should be cleared as quickly as possible after demolition


§  When any components of a structure or water mains to be demolished and are suspected to be consisting of asbestos, the project team should inform the ER. Any work which involves the use or handling of asbestos containing materials must strictly follow the following procedure:


§   employ a registered asbestos consultant to conduct an asbestos investigation and prepare an asbestos investigation report and an asbestos abatement plan;


§   submit the asbestos investigation report and the asbestos abatement plan to the Environmental Protection Department at least 28 days before start work on the asbestos containing materials;


§   notify the Environmental Protection Department of the date of commencement of work on asbestos containing materials at least 28 days in advance;


§   employ a registered asbestos contractor to carry out the asbestos work in accordance with the asbestos abatement plan;


§   employ a registered asbestos consultant to supervise the implementation of the asbestos abatement plan and the work of the registered asbestos contractor; and


§   employ a registered asbestos laboratory to conduct sampling and analysis for the asbestos work.

5.2.5    Good Site Practices

§  Responsible for good site practices, arrangements for collection and effective disposal to an appropriate facility, of all wastes generated at the site


§  Training of site personnel in proper waste management and chemical waste handling procedures


§  Provision of sufficient waste disposal points and regular collection for disposal


§  Appropriate measures to minimize windblown litter and dust during transportation of waste by either covering trucks or by transporting wastes in enclosed containers


§  Regular cleaning and maintenance programme for drainage systems, sumps and oil interceptors


§  A recording system for the amount of wastes generated, recycled and disposed of (including the disposal sites).

5.2.6    Trip Ticket System

A trip ticket system (TTS) for the removal of construction and demolition (C&D) materials from the Site to the designated disposal ground or alternative disposal ground will be implemented as according to the Particular Specification.  The system will be developed and presented in the Waste Management Plan to be prepared for the project. 


JV willl inform the Engineer of the account number of the billing account for disposal of construction waste under the Waste Disposal (Designated Waste Disposal Facility) Regulation (Cap. 354L). This is to enable the Engineer to check the disposal records posted at the Environmental Protection Department’s website.
