Mill.com provides a solution for managing food waste by drying and grinding food scraps into a resource called "Food Grounds." This process is facilitated by a device that resembles a kitchen bin, which operates quietly and requires emptying only once a month, eliminating unpleasant odors. The company targets environmentally conscious households in the continental U.S. with a subscription model that costs about a dollar a day, making it accessible to many consumers. Unlike traditional composting, the processed food waste can be used as animal feed, particularly for chickens, and customers can choose to keep their Food Grounds or have them picked up by the company. Mill.com aims to reduce the environmental impact of food waste, which is a significant contributor to global warming, and is positioned to capture a share of the sustainable waste management market.
