Burger King has announced a new pilot program aimed at reducing waste in several cities next year that will see the fast food chain adopt reusable food containers.

The company said on Thursday that it will trial the service, nicknamed “Loop,” in New York City, Portland, and Tokyo in 2021 in partnership with recycling company TerraCycle. The statement said that the select restaurants will provide the option of participating in the program, which offers “zero-waste packaging that can be safely cleaned and refilled to be reused, again and again.”
