Objectives:

  • Improve public understanding of LA’s three-bin waste system
  • Support the city's education and program rollout following SB 1383 waste legislation
  • Reduce contamination in recycling and compost bins, and drive behavior change
  • Make food waste guidance more accessible through multilingual support
  • Improve the customer experience with a friendly, easy-to-use tool available 24/7
  • Save staff time and resources by reducing incoming queries to their teams
  • Expand capacity to provide support outside of regular business hours

Outcomes:

  • Successfully reaching underrepresented communities that were previously hard to engage, such as South LA - a densely populated and diverse neighborhood with many multi-family homes
  • High interaction rates with 36% of conversations happening in languages other than English
  • With 97% of items sorted correctly and questions answered accurately, the system improved sorting habits, while reducing the need for city staff involvement
  • The service received high satisfaction - 91% of users said they got their questions answered
  • Unlocked new insights to help the team focus resources where they’re needed most - from common questions to most searched items
  • The digital assistant reduces pressure on city staff by providing automated, around-the-clock guidance and multilingual support
  • Tracked engagement by neighborhood to uncover location-specific challenges and needs

Hello EA Outcomes:
