Mill Industries Inc. provides a connected system for household food waste management. Its smart kitchen bin dries and grinds food scraps, drastically reducing volume and odors. The resulting nutrient-rich material is collected and repurposed as an animal feed ingredient, diverting waste from landfills and creating a valuable resource. This innovative approach offers a convenient and sustainable alternative to traditional waste disposal.
Mill was co-founded in 2020 by Matt Rogers and Harry Tannenbaum, both former Nest executives. Their insight stemmed from the environmental impact of food waste and its greenhouse gas contribution. They aimed to create an accessible solution, empowering individuals to manage food scraps efficiently and contribute to broader waste reduction efforts, thereby tackling a significant global challenge.
The company's system serves households and workplaces, offering an efficient organic waste solution. Mill envisions a future where discarded food is consistently recovered and valued, not merely landfilled. Their mission is to foster a circular food economy, making it simple and commonplace for everyone to keep food out of waste streams, working towards a more sustainable planet.
Mill is a Series C-funded technology company founded in 2020 that builds an automated food recycler—a sleek, countertop appliance that transforms kitchen food scraps into nutrient-rich grounds for gardens, farms, or backyard use, reducing waste volume by 80% without odors or mess.[2][4][5] It serves households, workplaces, and businesses like offices, hotels, universities, and data centers, solving the problem of food waste, which is a major driver of climate change and landfill overflow by making recycling effortless and habit-forming.[2][4][5] With nearly 10 million pounds of food diverted from landfills as of June 2025, Mill shows strong growth momentum, expanding from homes to enterprise solutions like Mill for Workplace, backed by AI analytics and fleet management software, and achieving real-world impact validated by updated life-cycle analyses.[2][5]
Mill was founded in 2020 in San Bruno, California, by Matt Rogers and Harry Tannenbaum, former colleagues at Nest where they developed the Nest Learning Thermostat and other smart home products.[2][5] Drawing from Nest's expertise in designing intuitive devices that drive sustainable habits, they identified food waste as a pervasive household issue and created Mill to make recycling as seamless as using a trash can, shifting perceptions from "food is trash" to "food nourishes the earth."[5] Early traction came from consumer adoption, award-winning design by Apple and Nest alumni, and rapid scaling to Series C-II funding, with pivotal expansion into workplaces in April 2025 amid rising corporate decarbonization demands.[2][5]
Mill rides the sustainability tech wave, capitalizing on food waste as a $1T+ global problem where households discard 30-40% of food, fueling methane emissions and climate change.[5] Timing aligns with corporate net-zero mandates, post-2020 consumer shift to home-centric green tech, and AI/IoT maturation for smart appliances—positioning Mill ahead of competitors like Waste Transformers' bulk digesters by focusing on seamless consumer/workplace integration.[2] Favorable market forces include rising ESG pressures (e.g., REITs like Vornado adopting it), policy incentives for waste reduction, and partnerships with farms for circular economy loops, influencing the ecosystem by normalizing on-site recycling and proving scalable decarbonization via data-driven insights.[2][5]
Mill's trajectory points to explosive B2B growth, building on 2025's workplace pivot and 10M-lb milestone toward enterprise dominance in food waste management, potentially integrating deeper AI for predictive waste analytics or expanding to retail/municipal scales.[2][5] Trends like AI-optimized sustainability, circular economies, and regulatory carbon taxes will propel it, evolving its influence from kitchen disruptor to infrastructure player in zero-waste buildings. As the effortless antidote to waste, Mill exemplifies how smart design turns planetary challenges into daily wins—keeping food out of landfills, one effortless load at a time.
