SB 1383: Methane Reduction Law

Organic waste (meaning materials such as food, yard waste, food-soiled paper, and natural fibers) makes up over half of California’s waste stream. When landfilled, it generates methane, an extremely potent greenhouse gas that contributes to climate change and public health concerns. In a statewide effort to reduce emissions of short-lived climate pollutants, particularly from organic waste, Senate Bill (SB) 1383 requires organic waste diversion and sets parameters for edible food recovery.

SB 1383 lays out a comprehensive guide for businesses and commercial kitchens to decrease food waste and prioritize edible food recovery and organic waste diversion from landfills. Simply put, SB 1383 requires that businesses implement programs to ensure organic materials are no longer put in the trash, with edible food instead being donated and the rest sorted for organic waste recycling.

The potential impact of diverting organics in San Diego alone is enormous:  

  • Free up 700,000 tons/year of landfill space
  • Create new markets and jobs worth $2,000,000/year
  • Save local businesses $20M/year in disposal fees
  • Avoid 127,000 metric tons/year of greenhouse gases
