Enhanced waste management


Enhanced waste management

Why did we do this?

The inherited supply base was large and fragmented and has little potential for driving forward recycling and waste minimisation improvements. Clear and challenging sustainability aspirations needed to be met and were reflected in the new contract.

The new contract and the associated site level improvements in bins, signage and logistical improvements gave us and our client a much stronger basis for the effective and sustainable management of waste across multiple sites.

How did we do this?

Working in collaboration, our procurement and sustainability team developed an innovative contract which sets out explicit recycling and waste arising working towards zero waste to landfill.

The tender process involved developing and using a balanced scorecard approach in assessing each of the tender responses.


  • Focuses on improving recycling performance and reducing waste arisings
  • Consistent level and quality of service provision across the 84-site estate including data reporting
  • Opportunities standardise bins and signage to improve staff awareness and understanding.
  • Dynamic approach to capacities – identifying opportunities for cost reductions
  • Partnership approach to developing and implementing improvement initiatives
  • Access to bespoke training and awareness opportunities for staff
  • Improved reporting on service and environmental performance
  • Flexible, cost effective approach to ad hoc projects

Facts and figures

  • Supplier review by a panel of experts against strict sustainability criteria covering operational and commercial needs
