Pollution prevention and control

including reduction of air emissions, greenhouse gas control, soil remediation, waste prevention, waste reduction, waste recycling and energy/emission efficient waste to energy

Implement waste management system

Example of applications:

  • Weighbridge on site for waste disposal monitoring

Low Cost applications:

  • Waste management plan
  • Waste generation and reduction management approach for inert C&D and non-inert C&D materials:
    1. Inert C&D materials (e.g. sand, bricks and concrete):
      • Exploration of land reclamation options;
      • Recycling of construction waste (i.e. concrete, masonry rubble and granular materials) for using as pavement sub-bases, trench backfilling material, drainage fill, etc.)
      • Disposal to public fills
    2. Non-inert material (e.g. bamboo, wood, paper, vegetation and organic materials):
      • Proper disposal to landfills and no illegal fly tipping
      • Exploration of recycling and reuse options
  • Space for sorting and segregation of construction and demolition materials, recyclable materials and chemical waste
  • Specific area on site for metal waste collection
  • Chemical waste record control
  • Apply waste management hierarchy and approach, 4R concept: Reduce, Reuse, Recycle, Replace in construction sites level, for example:
    1. Reduction: use of tower working platforms for renovation work instead of bamboo scaffolding
    2. Reuse: reuse offsite office building materials; reuse of concrete for backfilling
    3. Replacement: timber from well-managed forests
    4. Recycling: waste sorting area
  • Reduction of construction waste by recycling and/or reusing,e.g.
    • Recycling of damaged concrete slabs for backfilling on site
    • Recycling and reuse of rejected concrete for hard paving on site
    • Recycling of waste metal
    • Recycling and reuse of site facilities, including water tanks, barriers, water-filled barriers and metal scaffolding from other projects
    • Up-cycling banner or re-use it in other sites
    • Food waste recycling using food composters
    • Paper recycling
    • Coordination with neighbouring sites about construction backfilling reuse
    • Recycling of brick for road paving
    • Cement packaging recycling to suppliers
    • Chemical drum recycling to suppliers
    • Recycling of rock fill material for backfilling on other project sites
    • Delivery of broken concrete to other sites for reuse
    • Recycling of temporary wood and waste wood
    • Recycling of original metal from link bridges
    • Recycling of glass windows
    • Recycling of existing road surface asphalt bedding to asphalt manufacturer
    • WEEE recycling for electronic waste
    • Recycling of C&D waste backfill to private or government sites
    • Donate waste from tree felling to NGO for fertilizer
    • Exploration of alternative disposal grounds for recycling C&D waste by main contractor, the alternative grounds to include main contractor’s other private and public sector project sites
  • Waste monitoring and audit, compiling and verifying Waste flow table records
  • Packaging control and recycling programme with suppliers
  • Recycled Wood Plastic Composite, e.g. “Zen‧wood”

Sustainability KPI:

  • Waste generation using waste flow table to record types of waste generated on site (tones/m3)
  • Percentage of construction and demolition waste recycled by the end of the project (%)
  • Percentage of construction waste recycling, per project (%)
  • Percentage of waste metal recycled, per project (%)
  • Percentage of temporary wood and wood pallets recycled, per project (%)
  • Percentage of paper recycled, per project (%)
  • Percentage of temporary construction materials recycled, per project (%)
  • Percentage of construction material reused in other sites, per project (%)
