USA Today reports that Starbucks has started a nine-week pilot program in New York City to test the recycling of its paper cups, which total about 3 billion each year company-wide, GreenBiz reports.

It began placing recycling bins for the cups (not the sleeves, lids or other packaging pieces) at 86 locations in mid-September.

“We are testing the capability of the infrastructure to handle and accept our cups in the system,” Jim Hanna, Starbucks’ director of environmental impact, told GreenBiz.

What does that mean for consumers? The coffee giant will be comparing how many cups end up in the recycling bins versus the garbage to determine convenience. Hanna told Greenbiz that the program is relatively small, because 80% of cups leave Starbucks in their customers’ hands.
