California proposed banning single-use cups at chain restaurants for dine-in customers, building upon its plastic straw ban, mandated phase-out of virgin plastic use, and proposal to ban plastic retail bags.

Under SB 1167, introduced by State Sen. Catherine Blakespear, D-Encinitas, chain restaurants instead would be required to provide dine-in customers with reusable drinking vessels that are “a durable cup, mug, or glass containing hot or cold liquids that is cleaned and reused by the food service facility.”
