Disposable food service ware and polystyrene foam ban model ordinance

Jurisdictions in Sonoma County have implemented or are considering an ordinance, called the Ordinance to Prohibit Use and Sale of Disposable Food Service Ware and Other Products Containing Polystyrene Foam, to ban the sale of certain polystyrene foam products and limit the use of non-recyclable or non-compostable disposable food ware.

PS ordinance simple overview

What is being proposed

The ordinance addresses six areas:

  1. Prohibits polystyrene foam food ware distributed by food and beverage providers.

  2. Prohibits polystyrene foam food ware and specified polystyrene foam products sold by retail stores.

  3. Requires food/beverage providers and special events to use of unlined, fiber only compostable products or recyclable food service ware.

  4. Requires food/beverage providers to provide single-use straws, beverage lids, cutlery and to-go condiment packages only upon request. Customer may ask for the particular items, food providers may offer specific items, or the establishment may utilize a self-service area.

  5. Requires food/beverage providers to provide service ware products without added fluorinated chemicals (PFAS).

  6. Encourages use of reusables through optional fee for single-use or credit to customers providing their own containers.

Who would be affected?

In the jurisdictions where the model ordinance is adopted, the ordinance applies to those who sell or distribute disposable food ware and other specified products including food and beverage providers, retailers, and special events.

Examples include restaurants, bars, retail food vendors (including any store, shop, sales outlet, convenience store, grocery store, or deli), schools, faith-based organizations and food trucks operated within a jurisdiction. This ordinance also applies to city facilities (including lessees) and special events requiring a permit from the jurisdiction.

Are there exemptions?

A City Manager (or designee) may exempt a food provider, retail vendor or special event for the ordinance requirements for a one-year period upon showing the ordinance creates an undue hardship. A food provider, retail vendor or special promoter granted an exemption must reapply prior to the end of the one-year exemptions period and demonstrate continued undue hardship if it wishes to have the exemption extended. Exemptions are granted for intervals not to exceed one year.

What is compostable and recyclable?

Compostable means products made entirely from natural plant fibers such as paper, bamboo, wood, sugarcane, and wheat. These products must be accepted at the industrial or municipal facilities that aerobically compost Sonoma County’s food scraps and yard debris. For the purposes of this ordinance, products that contain or are coated with plastic polymers such as polylactic acid (PLA) or polyethylene (PE) are not compostable. Recyclable means using discarded materials to manufacture a new product. Recycling involves altering the physical form of an object or material and making a new object from the altered material.

Which products are exempt?

  • Foods prepared or packaged outside the jurisdiction. However, all vendors of pre-packaged items are encouraged to follow the ordinance.

  • Disposable food ware compostable or recyclable through Sonoma County’s commercial recycling programs.

  • Products containing polystyrene foam which pose a small risk of becoming litter.

  • Reusable polystyrene foam used for insulating or flotation purposes and is completely encased in more durable material. Examples include surfboards, boats, life preservers, construction materials, craft supplies and durable coolers not principally composed of polystyrene foam.

  • Packaging for meat and fish.

What are the alternatives?

Alternatives include food service ware products that are compostable, recyclable or those that can be cleaned and reused.

Are there financial impacts?

Replacements for polystyrene foam-based and disposal food ware products may be more expensive than their traditional counterparts. Food service vendors may choose to charge a separate fee for the compliant to-go packaging and products. The ordinance also allows food service establishments to charge a small fee to recoup the costs.

Encouraging your customers to bring their own containers both reduces waste and saves money. The ordinance encourages, but does not require, food service vendors to provide a rebate to customers who bring their own clean, reusable to-go containers.

Who is responsible for enforcement?

The City Manager, or designee, has primary responsibility and will be looking for good-faith effort from affected entities.

What is the purpose of the ban?

Restricting the use of polystyrene foam and disposable food service ware reduces landfill waste generated by businesses and consumers reduces litter escaping into the natural environment, waterways, and ocean.
