  • Well-organized sorting islands, clearly visible
  • Suitable bins for the type and volumes of waste collected, easily recognisable
  • Respect for the colour code
  • Use of the right bags (for example, blue for PMD)
  • Clear (what goes where) and visible sorting instructions  


  • Information, motivation and involvement of all employees and visitors, from the start and through different channels.
