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 (%)
