Environmental Impact Assessment Ordinance

Technical Memorandum

Annex 15


1. General

1.1 The annex describes the commonly adopted approaches and methodologies for assessment of waste management implications arising from the project. The methodologies may vary from case to case, depending upon the nature of wastes and the latest development in methods and techniques.

2. Uses with Special Requirements for Waste Disposal

2.1 The uses that need special requirements for waste disposal shall be, but not be limited to, the following:

  1. Offensive Trades:

    as declared under the Public Health and Municipal Services Ordinance, section 48.

  2. Chemical Waste Producing Industries:

    • electricity and gas generation
    • metal finishing
    • plastic electroplating
    • printed circuit board production and electronics
    • film processing and development laboratories
    • tannery and leather finishing
    • textile (including dyeing, bleaching and finishing)
    • chemical processing and formulation
    • land transport and shipping
    • manufacture of professional and scientific equipment

  3. Livestock Rearing: pigs, chickens, ducks, geese, pigeons and quails

  4. Community Facilities with Special Requirements for Waste Disposal:

    • abattoirs
    • hospitals/clinics and other health care premises
    • markets
    • other community facilities which generate radioactive waste, use ozone depleting substances or include incinerators may need special attention in the EIA processes.

3. Waste Management

3.1 Prior to considering the disposal options for various types of wastes, opportunities for reducing waste generation shall be fully evaluated taking into account the following factors:

  • avoiding or minimising waste generation through changing the design approach in the project planning stage;
  • adopting better management practices on site to reduce cross contamination and promote waste segregation during construction stage;
  • reusing or recycling waste materials in other construction activities in the construction stage;
  • diverting waste to other construction sites or to the public dumps for beneficial use in the construction stage;
  • using recycled materials for construction as far as practicable in the construction stage;
  • installing appropriate facilities for segregation of various types of wastes during the operational stage; and
  • arranging and facilitating collection of wastes by the appropriate waste recyclers as far as practicable in the operational stage.

3.2 Having taken into account the factors in section 3.1 above, the types and quantities of the wastes generated as a consequence shall be estimated and the disposal options for each type of waste described in detail. The disposal method recommended for each type of wastes shall be based on the result of the assessment in section 3.3 below.

3.3 The impact caused by handling (including labelling, packaging & storage), collection, and disposal of wastes shall be addressed in detail. This assessment shall cover but not be limited to the following areas:

  • potential hazard;
  • air & odour emission;
  • noise;
  • wastewater discharge; and
  • public transport.

When large quantities of wastes are identified, the impact on the capacity of waste collection, transfer and disposal facilities, especially the existing or strategic solid waste disposal facilities have to be assessed.

3.4 In addition to the waste management practices recommended for the project, the handling, collection and disposal of wastes, in particular livestock and chemical wastes, shall have to comply with the Waste Disposal Ordinance, and the Dumping at Sea Ordinance.
