Around 50 billion disposable drink cups are used every year in the US, but in the city of Petaluma, we will see if Americans have the discipline to reduce this footprint.

The city numbers around 60,000 people, and will participate in the Reuseable Cup Project. The aim is to furnish 30 local restaurants, from Starbucks to Taco Bell, with identical, durable, plastic drink cups, which customers and diners can use and then either leave on the table, or deposit in a network of dropoff bins around the city.
