R.City and Mill are teaming up to make it easy to send your food scraps to local farms in the Phoenix-metro area.
Phoenix-area residents can sign up for the R.City x Mill service to receive a Mill kitchen bin — which eliminates the messy work of home composting by drying and grinding food scraps overnight so they don’t smell or spoil — and access to the R.City pickup service and farm, where the food scraps will be used to cultivate soil and grow fresh produce.
This article covers common questions about the R.City + Mill program.

Free 30 day trial
By signing up for the R.City + Mill program, you are eligible for a 30 day free trial, meaning your credit card will not be charged until the first month with R.City + Mill is complete. The 30-day trial starts when your Mill kitchen bin arrives. When the end of the trial is nearing, you’ll receive an email reminder. You’ll have one R.City pickup during your free trial period. If you want to cancel, contact Mill or R.City within 30 days to have your bin picked up for free.
The arrival of your Mill kitchen bin & R.City bucket
Once you sign up, you’ll receive an email after your purchase invoice that details the window where you can expect to receive your Mill kitchen bin and R.City bucket. The Mill kitchen bin will be delivered via FedEx, and R.City will drop off your bucket on the date confirmed in email.
Your scheduled monthly pickup with R.City
Your monthly pickup day will be provided in a dedicated email from Mill a few days after you sign up. The scheduled day will be the same every month (for example, every third Thursday of the month). If you are an existing R.City customer, you will be moved to a monthly pickup day as well— these details will be provided via email.
If you have any questions about your bucket delivery or pickup date text 480.269.5149 or email R.City at email@example.com.
What can go in the bin
As a general rule of thumb, if it comes off your cutting board or plate, you can Mill it!!
Here are some examples:
- Small bones (like chicken or fish)
- Rinds, peels, pits
- Meat, dairy, eggs
- Coffee grounds
Things that don’t belong in the bin, but can go directly into your R.City bucket:
- Large bones (like beef, lamb, or pork)
- Hard shells
- Large amounts of sugar, cake, or cookies
- Large amounts of fibrous or starchy material (e.g. corn husks, potato peels)
- Houseplants or flowers
- Compostable plastics
- Paper containers, paper plates
- Napkins and paper towels
Things that don’t belong in the Mill kitchen bin or your R.City bucket:
- Large amounts of liquid, grease, or oil
- Pet waste
- Drugs or medicine
For an extensive list of what can and can’t go into the bin, use Mill’s food library in the Mill app. The app does not show what can go in your R.City bucket yet, so if you have any questions, don’t hesitate to reach out to us at firstname.lastname@example.org.
What to do with your Food Grounds and how to prepare for pickup day
Your bin should fill up about once a month. You can empty your Food Grounds into the R.City provided bucket that you receive around the same time as your Mill kitchen bin. The R.City bucket can accommodate a couple empties, in case your bin fills up before your pickup day. When your pickup day arrives, you’ll receive an email and/or text message from R.City and you can leave your R.City bucket outside.
How to order more R.City buckets if yours is filling up sooner than your pickup day
You can order extra R.City buckets for an additional fee. Text 480.269.5149 or email R.City at email@example.com for more information.
What to do if you forget to put your bucket out on pickup day
Text 480.269.5149 or email R.City at firstname.lastname@example.org.

What happens to this service during extreme weather conditions, such as heavy rain or heatwaves
It is business as usual, unless you are notified otherwise directly from R.City. If your pickup day is moved due to extreme weather conditions, and your R.City bucket is full, you can empty your Food Grounds into any temporary container that has a seal / lid.
Discounts or referral programs
We do currently have a referral program available— please reach out to us at email@example.com and we’ll share more details!
Your monthly payments will be processed by Mill— you will be charged $35 at the start of each month.
For existing R.City customers transferring to the R.City + Mill program
You will receive detailed emails with guidance on how to get started, but in case you’re looking for a few more details:
- Your 30-day free trial begins, and your existing R.City plan ends, when your Mill kitchen bin is delivered.
- Once your Mill kitchen bin is delivered, R.City will come as usual for your next pickup— after that, you will get a new monthly pickup day
- Your first monthly pickup will be during the 30-day trial period
- R.City will do a bucket swap and pick up shortly after your trial starts, and another pickup before trial ends if requested.
- Payments to R.City end when trial starts, and if applicable, R.City will issue a refund for unused amounts.
The Mill kitchen bin uses about 1 kilowatt hour per day on average. This is equivalent to a high efficiency dishwasher. For more information, see this article.
Long Dry & Grind cycle
It’s common for your bin to take 5-10 hours to completely dry out your Food Grounds. See this article for more information on what can cause long Dry & Grind cycles. If you think that your bin is taking longer than it should, reach out to firstname.lastname@example.org.
When the Mill kitchen bin is running a Dry & Grind cycle, the fans sound like white noise and are about as loud as a dishwasher (~44 dB). If you put in pits or bones, you might hear a quick, loud snap or clunk. Every now and then it might make a funny creak or groan as it mixes. The bin’s fans run at a super low-energy speed throughout the day to help maintain a negative air pressure so that the bin stays smelling fresh.
