For Restaurants

A recycling program that turns a big mess into big benefits.

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 into thick layers inside drainpipes and sewer pipes, constricting water flow the way cholesterol affects blood flow in arteries. 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. Our Water Pollution Prevention Program targets FOG as a “pollutant of concern” and works towards improving water quality through pollution prevention strategies. 

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. Restaurants can sign up for free collection services. It only takes a few minutes to start saving. For residents, we have permanent drop-off locations and yearly collection events throughout the City.
