Itgreen's 'Return It' is an eco-friendly service that replaces disposable containers used for food delivery with reusable multi-use containers. Return It uses hygienic stainless steel multi-use containers and collects leftover food waste upon return — catering to both B2C customers such as office workers who want a convenient meal and B2B clients such as companies committed to environmental sustainability. Selected as the sole operator of Seoul's pilot project for multi-use delivery containers, Return It is available in the Gangnam and Seocho areas through Yogiyo, Samsung Welstory, and Dosi Kitchen.
