Saturnbird Coffee launched its third edition of Project Return in 43 cities across China from Oct 16 to 18.

The project collaborated with 64 places, including cafes, bookstores and furniture shops, using their space to recycle Saturnbird's small empty coffee containers.

The project is scheduled twice a year, and calls on customers to bring their used containers and exchange them for free gifts, including shopping bags and headphone sleeves.

Customers can also choose to donate the containers. Saturnbird will donate money according to the quantity of the donated containers.

So far, the three public benefit organizations have received over 10,000 containers each, and Saturnbird will donate 50,000 yuan ($7,453) to each organization to help with marine environment protection and wildlife protection.

More than 20,000 people joined the project, and over 1.4 million containers were recycled. The recycled containers will not be used as containers again, but will be made into other devices.
