Used cooking oils are a serious problem for San Francisco's sewers, clogging the pipes and costing us all a lot of money--over $3.5 million each year to unclog the pipes. When poured down the drain, cooking oil solidifies inside sewer pipes, constricting water flow. Clogged sewers result in unsanitary back-ups, overflows onto streets, foul-smelling odors, and costly damage to sewer infrastructure.
Residential kitchens and commercial restaurants are the largest controllable sources of fats, oils and grease (FOG) in the City’s sewer system. Launched in 2007, SFGreasecycle is a citywide effort that diverts FOG away from the sewers and turns it into biofuel to run San Francisco fleets.
SF residents can do something about the grease problem. The San Francisco Public Utilities Commission has partnered with retailers in San Francisco and Treasure Island for convenient locations to drop off used cooking oil year-round. The used cooking oil is then converted to biofuel.
Restaurants can also sign up for free collection services.
