1.4 The Waste Management Policy

To demonstrate the KSZHJVs commitment on the continual improvement of our waste management performance, an Environmental Management Policy includes the waste management has been established. It aims to communicate KSZHJVs waste management mission, vision and beliefs to the staff and public, it also provides a framework in guiding the project team the basic requirements to be achieved in waste management.

The hierarchy is illustrated below. It attempts to evaluate waste management practices and selects the best practical option since conceptually it makes sense to avoid producing waste rather than developing extensive treatment schemes. Good planning and site management practices also help minimizing over ordering or misuse of construction materials. The overall objective is to reduce and minimize the amount of wastes generated, hence reducing the costs of waste handling and disposal.

The current policy related to the dumping of C&D material is documented in the Development Bureau (Works) Technical Circular No. 09/2011, Enhanced Control Measures for Management of Public Fill. Construction and demolition materials that are wholly inert, namely public fill, should not be disposed of to landfill, but taken to public filling areas, which usually form part of reclamation schemes.

Under the WDO and the Charging Regulation, wastes can only be disposed of at designated waste disposal facilities licensed by EPD. For construction work with a value of more than HK$1M, the main contractor is required to establish a billing account at EPD before transporting the construction waste to the designated waste disposal facilities (e.g. landfill, public fill etc.). The vessels for delivering construction waste to public fill reception facility would need prior approval from EPD. Breach of these regulations can lead to a fine and/or imprisonment.

1.5.2.4 The Land (Miscellaneous Provisions) Ordinance

The Land (Miscellaneous Provisions) Ordinance requires that dumping licences be obtained by individuals or companies who deliver public fill to public filling areas. The Civil Engineering & Development Department (CEDD) issues the licences under delegated powers from the Director of Lands.

3 SITE SPECIFIC WASTE MANAGEMENT

3.1 Waste Policy Principles

Refer to hierarchy abovementioned in Section 1.4, a further explanation of the hierarchy of waste management on site is detailed below.

3.1.1 Hierarchy of Waste Management

Key to waste management is to reduce the amount of waste generated from the work site. Waste management options would be exercised in accordance with the hierarchy stipulated in the following table:

Avoidance and Minimization	Avoid and minimize waste through careful planning and design works.
Reuse	Reuse construction waste such as excavated material, used wooden plants and ferric materials.
Recovery and Recycle	Undertake on-site or off-site waste recycling.
Treatment and Disposal	Properly treat and dispose of waste in accordance with legislative requirements, guidelines and good practices.

Table 1: Hierarchy of Waste Management

In the context of waste reduction, environmentally responsible purchasing would involve the introduction of practices that discourage unnecessary purchases and encourage the purchase of products with reduced packaging, increased durability and materials with high recycled content, such as, recycled paper, steel and other raw construction materials.

Waste minimization is best achieved through careful planning, design and supervision. Good management practices would reduce and prevent large amount of waste generated. Raw materials would be managed from the first instance before they are ordered and delivered to the site. Good estimation and planning would minimize the amount of raw materials wasted. The generation of waste would be controlled at source.

3. 2 Waste Reduction

Specific measures will be implemented to reduce the generation of waste materials, and thus minimize the amount of waste disposal to landfills. The measures will include:

l Sorting on site to recover the inert portion of C&D materials;

l Sorting of plastic waste and deliver to recycling company;

l Recover all metallic waste for recycling;

l Recover all cardboard and paper packaging, and properly stockpile them in dry and covered condition to prevent cross contamination;

l Use of the materials (such as formworks and hoardings) in the construction would be calculated before purchasing in order to minimize waste generation.

l Use of metal formworks and hoardings, and they would be recycled after demolition on site as far as it can before disposal.

4 WASTE MANAGEMENT PROCEDURE

The quantities of disposal C&D materials will be recorded under the barcode trip ticket system by using the C&D Material Disposal Delivery Form. In addition, the filled CHIT / Vessel CHIT will also be presented to the landfill / public fill site as part of the system for the disposal charging scheme which had already been officially effective in January 2006. Waste transaction records could be obtained either in the waste disposal facilities right after the transaction or retrieved from the EPD bill statement each month.

According to our latest site investigation results, all the boreholes were found to have a very low organic matter. It is therefore not anticipated to have biogas generation. In addition, the specifications of the project are not required to have any precautions during construction works. It is also not anticipated to use public fill for reclamation below +2.5mPD.

Borehole No.	Depth (m)	Organic Matter (%)
VC10	0.0 0.9	1.3
VC10	12.9 13.9	0.5
VC3	0.0 0.9	1.5
VC3	13.9 14.9	3.6
VC4	0.9 1.9	1.3
VC4	10.9 11.9	4.6
VC9	0.0 0.9	0.5
VC9	10.9 11.9	1.0

Table 2: Organic matter of the boreholes

4.1 Estimate Quantities of C&D Materials / Wastes

The following types of waste would be generated from the works.

l Inert C&D materials (Removal of Surcharge);

l Inert C&D materials (Broken concrete);

l Non inert C&D materials;

l Marine Sediment;

l Chemical waste;

l General refuse; and

l Recyclable wastes (paper, plastic and metal)

Table 3: Estimated Quantities of C&D Materials and Proposed Disposal Outlet

4.2 Acceptance Criteria for the Government Disposal Facilities

Inert C&D materials shall dispose to Fill Banks (e.g. Tuen Mun Area 38, TKO Area 137 etc.) Mixing of non inert C&D materials with inert C&D materials will result in rejection for disposal of C&D materials at Fill Banks.

For non-inert C&D materials, the designated disposal facility is depended on the waste depth / weight ratio of the vehicle to transport the non-inert C&D materials off site.

Vehicle Type	Waste Depth	Weight Ratio (note)	Designated Facility
Non-demountable Vehicle	Over 1.5m	No restriction	Landfill
	1.5m or below	0.20 or below
		Over 0.20	Sorting Facility
Demountable Vehicle	Over 1m	No restriction	Landfill
	1m or below	0.25 or below
		Over 0.25	Sorting Facility

Table 4: Waste Acceptance Criteria for landfill and sorting facilities for non inert C&D Materials

Note: Weight ratio = The net weight of C&D materials / Permitted Gross Vehicle Weight

KSZHJV will comply with the acceptance criteria laid down by the operators of the corresponding fill bank(s) and landfill(s), as outlined below:
