Encourage users to sort their waste at source by making the collection of residual waste more restrictive; this is the solution implemented by SUEZ for the town of Arnhem:
- separated waste such as paper, packaging waste and organic waste are always collected through door-to-door rounds or at the foot of buildings;
- residual waste must be deposited in an underground container in the neighbourhood.
Propose specific containers
We implemented the following principle for this solution:
- inhabitants of low-rise buildings have three mini-containers in their building for: paper/cardboard, plastic packaging, organic waste (fruit, vegetables, garden waste). Their residual waste must be deposited in an underground container within a reasonable walking distance and accessible with a personal badge;
- inhabitants of high-rise buildings must deposit their packaging waste, paper/cardboard and residual waste in underground collection containers. Organic waste is collected every fortnight using a regular city waste bin.
All mini-containers are fitted with an RFID chip providing data on their use and changes to collection rounds.
Communicate about the new collection system
To make the pilot project a success, we consulted residents about their consumption habits, the choice of container location, the appropriateness of the system and the quality of service.
A field communication campaign was also deployed:
- 12 "waste coaches" in daily contact with residents;
- posters in each district publicising the progress made and encouraging them to make even more efforts;
- Three satisfaction surveys made just before the launch, six months after and one year after, enabled some adjustments to be made to the system.
