The Mill kitchen bin recycles kitchen scraps into dried, ground-up food that we call Food Grounds. Food Grounds are still food, minus the water, bulk, odor, and ick.

Food Grounds aren’t compost. Compost is produced when microbes digest organic matter, which takes weeks or months, not hours — despite what others might say. While Food Grounds can be made into compost or added to your garden, it is a delicate process that can result in mold, cause odors, and attract pests.

Sending us your Food Grounds is not required, but we highly recommend it if you don't have a use for your them at home. According to the EPA and the UN, the best and highest use for uneaten food — after feeding people — is feeding animals that help to feed people. When you send us your Food Grounds, we turn them into food for chickens, providing the greatest possible impact.

The food we throw away is still food. It takes a lot of land, water, fertilizer, and effort to get food from the farm to our tables — so it’s important for our food to stay in the food system.

There are ways to make the best use of food that’s uneaten. First, feed people. Then, feed animals that produce food for people. Both options align with the EPA’s food recovery hierarchy and the hierarchy of destinations for achieving United Nations Sustainable Development Goal Target 12.3.

We receive shipped Food Grounds at our feed manufacturing facility where we turn them into a safe chicken feed ingredient through inspection, screening, heating, and blending.

We’ve worked through most of the necessary scientific and regulatory processes to distribute our nutritious chicken feed ingredient commercially. We’ll share more on our progress later this year!

If you purchase your Mill, then you pay the full amount when you're placing your order. If you finance your Mill, then you'll make your first payment 30 days after placing your order.

If you have Mill pickups enabled on your account, you will know it’s time to empty the bin when the Food Grounds get close to the fill line inside the bucket.

Mill pickups come with prepaid boxes and liners that you can empty your Food Grounds into. The average household will need to empty their bin every 4-5 weeks, but it really depends on the amount of kitchen scraps you generate. 

Each box holds about two bin-fulls. We recommend storing them in a dry place indoors with the bag liner closed until your box is ready for a full send!

Mill is designed to improve your kitchen experience and help you keep food out of landfills.

– Shrinks food by 80%: The Mill kitchen bin turns your peels, bones, stalks, and leftovers into nutrient-rich grounds. No weird smells. No drippy bags.

– Not-so-picky-eater: Unlike compost, the bin can handle whatever you can’t eat — even meat and dairy products.

– Fewer trips to the bin: Add food scraps to your bin all day, every day. The bucket can collect dry grounds for weeks without needing to be emptied. And you don’t need any additives.

– Year-round service (optional): You can ship your Food Grounds to Mill even in the winter when curbside compost collection services may not be available.

– Impact tracking: See the amount of food scraps you’re adding and learn ways to improve your climate impact over time.

You can start the cancellation process through the account portal on our website (click “Update plan” and then “Cancel service plan”).

Our support team will reach out to you once you start the cancellation process to help you return the bin and complete cancellation. We’ll email you instructions on how to prepare the bin for return, and send a box to pack up the Mill kitchen bin and a prepaid return label to the address connected to your account. If these should be sent to a different address, please let us know right away.

Once you’ve packed up the bin, contact Mill Support to schedule a FedEx pickup or drop it off at FedEx. You must return the bin within 30 days of your current billing period ending. We’ll send you an email confirming your plan has been canceled once your bin has been returned!

If you do not return the bin in your possession, your plan will remain active and you will continue to be charged until you return the bin. Please contact our support team if for any reason you are unable to return a bin.
