Why Are We Doing This?

SB 1383 is California’s organic waste recycling law. It requires communities to reduce organic waste sent to landfills and properly separate food scraps, food-soiled paper, and yard trimmings.

As part of these requirements, state-mandated annual route reviews help identify contamination and support correct sorting.

The goal is to help make sure materials are going into the right cart and provide education when materials are not sorted correctly.

What Happens During a Route Review?

Route reviews are conducted randomly during regular collection service. If your collection stop is selected, your garbage, recycling, and compost carts will be checked.

The auditor will lift the lid of your garbage, recycling, and compost carts and take a quick visual look at the contents.
