Kitchen bin converts food scraps into chicken feed via subscription. Bridging consumer food waste with commercial feed supply chains. ## Company Overview Mill is a food waste reduction company whose smart kitchen bin converts household food scraps into dry, odor-free chicken feed that Mill collects and routes into commercial poultry feed supply chains — creating a circular economy that simultaneously addresses household food waste and commercial feed ingredient demand. The company has raised $100 million in total financing and operates a subscription model where households pay for the bin and collection service. The innovation is the dehydration and grinding process inside the bin: food scraps are processed overnight into "Food Grounds" — a dry, shelf-stable material that eliminates odors, prevents spoilage, and can be stored until Mill's collection service picks up. This dehydration step is the key to making household food scraps commercially usable: wet organic waste has too short a shelf life and too high a pathogen risk for commercial feed applications, but dry processed scraps from controlled household sources meet regulatory requirements for poultry feed. Mill's model creates aligned incentives across the value chain: consumers pay a subscription for a premium product that reduces kitchen waste and guilt; Mill generates revenue from the subscription and the feed ingredient sale; commercial feed producers receive a domestically-sourced, consistent feed ingredient at competitive cost. As ESG pressures on food companies intensify and regulatory frameworks around food waste crystallize, Mill's closed-loop model becomes increasingly relevant to institutional food service customers beyond individual households. ## Frequently Asked Questions ### What does Mill do? Smart kitchen bin that converts food scraps into dry chicken feed ('Food Grounds') via overnight dehydration — subscription service with Mill collecting and routing to commercial poultry feed supply chains. ### How much has Mill raised? $100M total raised. ### How does the circular economy model work? Consumers pay subscription + collection; Mill sells processed food scraps as poultry feed ingredients; feed producers get consistent domestic supply. All parties have aligned financial incentives. ### Why is the dehydration step critical? Wet food waste has too short a shelf life and pathogen risk for commercial feed. Mill's overnight dehydration creates dry, shelf-stable, regulatory-compliant feed ingredients from household sources. ### What is Mill's Food Grounds product? Mill's smart kitchen bin processes food scraps overnight using gentle heat and air circulation, reducing them to a dry, odorless material called Food Grounds — similar in composition to chicken feed. Mill collects Food Grounds from customers and routes them to poultry farms, where they replace conventional feed. ### How does Mill's subscription model work? Mill is a subscription service at approximately $33/month (or $396/year) that includes the smart bin hardware and Mill's food-to-feed collection service. Subscribers ship their Food Grounds to Mill using prepaid bags, and Mill handles the logistics of connecting this material to poultry farm partners. ### What is the environmental impact of Mill's system? Food waste in landfills is a significant source of methane, a potent greenhouse gas. Mill claims the average household diverts approximately 100 pounds of food waste annually, preventing landfill methane emissions while creating a nutritious chicken feed alternative that reduces the land, water, and energy required to produce conventional feed. ### Who founded Mill and how does it connect to Nest's founding team? Mill was founded by Matt Rogers, who also co-founded Nest (the smart thermostat company later acquired by Google). Rogers applied the same consumer hardware subscription model from Nest to food waste, building a premium smart appliance that solves a consumer problem with broader environmental and food system benefits. ### What is Mill? Mill is a home food recycling appliance and service that helps households reduce food waste. The Mill bin grinds and dehydrates food scraps overnight into a dry, odorless food grounds material that can be returned to Mill for use as chicken feed, reducing landfill food waste. ### How does the Mill bin work? Users toss food scraps into the Mill bin throughout the week. The bin automatically grinds, dehydrates, and de-stinks food waste overnight using a quiet motor and heating element. The resulting food grounds are a fraction of the original volume and have no odor or pests—ready to be mailed back to Mill in prepaid bags. ### What happens to the food grounds that Mill collects? Mill partners with farms to convert the collected food grounds into animal feed—specifically chicken feed—completing a circular economy loop where human food waste becomes agricultural input rather than rotting in landfills and generating methane. ### How much does Mill cost and who is it for? Mill charges a monthly or annual subscription fee (approximately $33/month annually) that covers the bin and return shipping of food grounds. It targets environmentally conscious households and families with significant food waste who want a convenient, odor-free composting alternative. ### What is Mill? Mill is a consumer food recycling company whose kitchen bin uses heat and air movement to dry and grind food scraps overnight, turning them into Food Grounds that are shipped back to Mill to be converted into chicken feed — creating a closed-loop food waste reduction system. ### How much has Mill raised? Mill has raised over $100M from investors including NEA and Prelude Ventures, founded by Matt Rogers (co-founder of Nest) and Harry Tancredi, bringing hardware product design expertise to the food waste problem. ### What is the environmental impact of Mill? Food waste is a top contributor to methane emissions in landfills and represents massive resource inefficiency in the food system. Mill claims its system eliminates the methane that would be produced from landfill decomposition of food scraps. ### How is Mill priced? Mill operates on a subscription model — the bin is provided through a monthly plan that covers the device, app, and the Food Grounds collection service, making the total cost comparable to a premium kitchen appliance subscription. ## Tags b2b, saas --- *Data from geo.sig.ai Brand Intelligence Database.
