Join us for an in-depth discussion with the City of San José as they share the results of their 2024 Contamination and Recycling Tagging (CART) program. With over 66,000 households reached and a statistically significant drop in recycling contamination, San José’s pilot initiatives demonstrate the power of combined education, outreach, and technology.

We have an amazing lineup of panelists from the City of San José with special opening remarks by Marshalle Graham from CalRecycle. 

Learn how the City of San José-

  • leveraged Zabble’s AI-powered bin inspection platform to collect data and track contamination

  • assessed the impact of tactics like in-mold cart lids, larger garbage carts, and direct feedback provided via cart tags

  • evaluated what worked (and what didn’t), and offer practical guidance for jurisdictions facing similar challenges
