Seattle Food Waste Disposal Requirements for Restaurants

Seattle's Mandatory Food Waste Separation Ordinance

Seattle requires all food service establishments to separate food waste, food-soiled paper, and compostable materials from regular trash. This mandate falls under Seattle's Zero Waste ordinance and is enforced by the Seattle Department of Neighborhoods, separate from FDA health codes. Restaurants must use clearly labeled bins and partner with a certified composting facility or waste hauler approved by the city. Violations can result in fines starting at $100 per day for non-compliance. The city specifically prohibits food waste in regular landfill garbage, making separation non-negotiable for all food establishments.

Grease Trap and FOG (Fats, Oils, Grease) Management

Washington State and Seattle both regulate fats, oils, and grease (FOG) disposal through plumbing codes and environmental protection rules. Restaurants must install and maintain grease traps or interceptors approved by the Seattle Department of Construction and Inspections, with regular pumping required (typically every 3-6 months depending on volume). FOG cannot be discharged directly into municipal sewer systems, as it causes blockages and environmental damage. Seattle's Public Utilities department monitors sewer overflows and can cite restaurants for improper grease disposal. Unlike federal FDA standards which focus on food safety, these requirements address infrastructure protection and pollution prevention.

Compliance Documentation and Reporting Requirements

Seattle restaurants must maintain records of waste disposal contracts with licensed haulers and composting facilities, which may be requested during health inspections or city audits. The Seattle Department of Neighborhoods publishes guidance for food service establishments on compliant waste practices and acceptable vendors. Washington State's Department of Ecology provides additional oversight for larger waste streams and environmental impact. Restaurants should document grease trap maintenance with pump-out receipts and share these records with the city if requested. Staying current with vendor certifications and disposal documentation protects your business from penalties and demonstrates good-faith compliance efforts.
