Starbucks is testing a reusable cup program at 12 of its stores in Napa and Petaluma, California. The test will be in effect until October 22.

As a part of the coffee company’s continued sustainability efforts, customers at the select locations can either bring their personal cups for use in the cafe or drive-thru, use a Borrow A Cup from Starbucks, or choose For Here Ware, which are ceramic or glass cups for customers who dine in.

The reusable tests align with Starbucks commitment to cutting its waste footprint in half by 2030. The 12 stores in California join the 25 markets around the world that the company has already began testing its reusable program in.

“These types of tests are extremely important so that the company can understand all the different ways we can make an impact and move towards goals that we have set for the future,” said Tonya Palacios, Starbucks district manager.

Innovation hits the burger industry as well. Whataburger has opened a digital-forward location near the University of Alabama in Tuscaloosa. The new location has a smaller dining room and simplified menu.

With a team of 65, the new location has a new kitchen design that prioritizes efficiency and accepting online, app and in-store kiosk orders. New food lockers also boost quality and convenience, according to the company, as orders will be kept warm and customers can retrieve food seamlessly.
