What is Mill?

Mill was created in an effort to close the loop on food waste—to keep food out of the landfill and in the food ecosystem.

A Mill membership comes with a kitchen bin for food that would otherwise be wasted—kitchen scraps go in, Food Grounds come out. Food Grounds can collect in the bin for weeks without having to be emptied; they’re dry and compact, so they take up less space than normal food would in the trash. Food Grounds can be sent back to Mill to turn it into food for chickens, or mixed it in with household compost.

The app

The Mill app is the window into seeing what the kitchen bin is up to. Users can schedule and control when they’d like the bin to run, schedule free Food Grounds pickups, and check out what can and can’t be processed in the kitchen bin. As the lead designer, I worked closely with PM and engineering to design, build, and refine the app.

Why it matters

Uneaten food is the most common material in landfills and half of it comes from our homes. When that food rots, it produces methane, a gas that’s 80x worse for the climate than CO2 emissions. Sending kitchen scraps to the landfill creates 3.5x the emissions compared to using a Mill kitchen bin and mailing Food Grounds back to Mill, so they can feed chickens. Check the math.
