Single-Family Recycling Cart Tagging Program

A 2022 study found that 57% of items placed in San José single-family recycling carts were not recyclable- establishing a baseline for a new initiative to recover more recyclable materials. As of March 2024, the Contamination And Recycling Tagging (CART) Program provides direct, household specific feedback through cart tags to help residents recycle right and reduce contamination. A follow up 2024 study showed that the amount of non-recyclable items dropped to 41%, which reflects the work of residents and the effectiveness of direct education. Let us work together to continue recycling right to lower the amount of non-recyclables to 10% or less. Every household that recycles correctly helps keep fees low, conserves resources, and reduces landfilled waste.

How The Program Works:
City staff check recycling carts placed curbside on collection days from 6:00 a.m. to 10:00 a.m. Staff lift the lid to check contents that are visible at the top, without sifting through materials, to identify non-recyclables and recyclables contaminated with leftover food and/or liquid. Staff record cart size, fullness, contamination level and types. No personal information is collected. Depending on what is found, residents may receive one of the following feedback tags:

  • “Good Job” tag – items are recyclable and clean. Keep up the good work!
  • “Oops” tag – non-recyclable items or soiled recyclables identified. The tag will include specifics on contaminated items and provide information on how to recycle right. 

All tagged carts will be collected unless Household Hazardous Waste is found. If hazardous waste (such as batteries, electronic devices with embedded batteries, paint, motor oil cans, and aerosol cans) is present, the recycling service provider will leave a Non-Collection Notice.
