When in doubt, throw it out!

Our goal is to keep this city beautiful and help make it easy for residents to do the same. Use this guide to determine which materials are considered recyclable and which are not.

Any item placed in your recycling cart will be sorted by a recycling processor that will determine the type of material. As long as the item isn’t on the “Not Acceptable” list, place it in the blue cart and we’ll take care of the rest.


For the most up to date list on what you can and cannot recycle within the county of San Luis Obispo, please refer to the list provided by the San Luis Obispo Integrated Waste Management Authority (IWMA) available here.


Please do not place any recycling or garbage in your green cart. Everything in the green cart needs to be compostable. Animal waste is not accepted as green waste.

If we can not accept a material in the blue (recycle) container or green (organics) container then it will be placed in the gray/black (landfill) container. This also includes contaminated materials. Contamination can make any recyclable material ineligible for recycling. Some materials, like metals, can be recycled even with high levels of contamination.
