The San Francisco Mandatory Recycling and Composting Ordinance (No. 100-09) is a local municipal ordinance requiring all persons located in San Francisco to separate their recyclables, compostables and landfilled trash and to participate in recycling and composting programs. Passed by the San Francisco Board of Supervisors in 2009, it became the first local municipal ordinance in the United States to universally require source separation of all organic material, including food residuals.
