You will know it’s time to empty the bin when the Food Grounds get close to the fill line inside the bucket.
If you opt in to Mill Pickups, the subscription comes with prepaid boxes and liners that you can empty your Food Grounds into. The average household will need to empty their bin every 4-6 weeks, but it really depends on the amount of food scraps you generate.
Each box holds about two bin-fulls. We recommend storing them in a dry place indoors with the bag liner securely closed until your box is ready for a full send!
