Reducing waste is good for reducing all three of the triple bottom lines of:

  • environment
  • financial (the project budget and your business)
  • social/community impact:


  • Conserve space in existing landfills and cleanfills and reduce the need for future landfills and cleanfills.
  • Reduce pollution and energy consumption associated with the manufacture of new materials.
  • For destructive demolition, reduce other impacts (e.g. noise, dust and traffic) on surrounding properties and streets.


  • For construction, more efficient use of products means reduced costs of purchasing new materials.
  • Improve work efficiencies through accurate detailed design, a focus on reducing rework, temporary works and mistakes.
  • Reduce waste disposal costs.
  • For demolition, earn revenue from salvaged building parts and recycled materials. Use our REBRI Resource Routing Calculator to calculate whether it is economic to dispose to landfill or recycle a material.
  • Win contracts for projects that specify waste reduction procedures.
  • Improve productivity of staff.


  • Minimise the effect of hazardous or nuisance wastes on the community by sound management.
  • Innovation and challenges (for example, the training and skills required for deconstruction) can help to attract and retain employees who are keen to develop skills.
  • A high level of client satisfaction could enhance your company's image and encourage repeat business.
  • Improve site safety through better waste management.
  • For demolition, reduce risks from hazardous materials due to more careful dismantling techniques and correct removal and disposal (e.g. asbestos).
