May 4, 2017 MEMO TO: Mike White, Council Chair F R 0 M: Gary Saldana, Legislative Analyst//4 SUBJECT: POLYSTYRENE RESEARCH (PAF 17-100C) Below is an assessment of definitions of polystyrene food containers from various cities and counties that have enacted polystyrene food container bans. The definition of “Polystyrene” in the County of Maui Bill 127(2016) is identified followed by definitions from the City of San Jose, Montgomery County in Maryland, Alameda County in California and City and County of San Francisco.

San Jose- Polystyrene foam” means a thermoplastic petrochemical material made from a styrene monomer and expanded or blown using a gaseous agent (expanded polystyrene) including, but not limited to] fusion of polymer spheres (expandable bead polystyrene), injection molding, form molding, and extrusion blow molding (extruded foam polystyrene). “Polystyrene foam: is commonly made into disposable food service ware products.
