 Starbucks has come up with a new type of compostable coffee cup. KCBS's Matt Bigler says the switch is part of a larger effort to move away from plastic food containers. At this Starbucks east of San Francisco, the plastic dome lids that usually top cold beverages are now white. This customer was happy to see the new compostable cups. I think that's a great idea. It's better for the environment. The change seems to be in accordance with the local anti-plastic ordinance. We are so excited about it.
