Mill + R.City

About Us

Mill + R.City is revolutionizing how Metro Phoenix handles food waste. Our innovative food recycling bin dries and grinds food scraps into lightweight, odorless grounds, which are then returned to local farms through partnerships like R.City—closing the loop from plate to produce. Founded by Nest alumni Matt Rogers and Harry Tannenbaum, Mill applies smart home innovation to create sustainable habits at home, starting in the kitchen. We're on a mission to make food—not waste—by preventing food scraps from ending up in landfills. With Mill, composting is clean, easy, and impactful. Join us in reshaping how we think about waste and support local agriculture in the process.
