It's not compost ... yet
Machines don’t make compost — nature does. Mill gives you a running start, turning your uneaten food into dry grounds that can break down faster.
So, what are Food Grounds?
All the food you don’t eat — even meat, bones, and dairy — dried, ground, nutrient-rich, and ready to use or store.
Shelf-stable
Food Grounds are low moisture, with no microbial activity, so you can store them for months.
Compact and dry
With 80% less volume than wet scraps, they are easy to handle, transport, and put to use in your garden.
Nutrient-rich
Proteins, fats, and carbohydrates remain intact, and ready to be broken down in soil or compost.
Versatile
Food Grounds aren’t just for your garden. You can also feed them to chickens — or let Mill get them to a farm.
