R.City and Mill are teaming up to make it easy to send your food scraps to local farms in the Valley.
Phoenix-area residents can sign up for the R.City x Mill service to receive a Mill food recycler — which eliminates the messy work of home food waste diversion 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. If you don’t find an answer to your question, use the search bar in the top right of this page to search for other Mill Support articles, or reach out to our Support team at rcity@mill.com and we’ll get back to you as soon as we can!
Am I within the service area to get the R.City + Mill program and pickups?
This map shows the Mill x R.City service area. If you’re outside of this service area and still want a Mill food recycler, you can still order a bin at www.mill.com.
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 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.
What is included in the R.City + Mill program?
- Use of the food-recycling Mill food recycler and R.City bucket.
- Monthly pickup of your R.City bucket (we will email your date).
- Quarterly compost or farm box delivery.
- Filters, repairs, and even bin replacement for your Mill food recycler.
- A dedicated support team of real people.
The arrival of your Mill food recycler & 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 food recycler and R.City bucket. The Mill 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 info@recycledcity.com.
Can I add a second R.City bucket, so I have 2 R.City buckets instead of just one?
Yes! This just increases the monthly price from $35 to $37. Reach out to us at rcity@mill.com and we’ll make it happen.
The bin is about the size of a standing trash can. The exact dimensions are:
- Height: 27.2 in
- With lid clearance: 37.5 in
- Width: 16.6 in
- Depth: 13.8 in
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)
- Fruits
- Vegetables
- Rinds, peels, pits
- Meat, dairy, eggs
- Coffee grounds
- Leftovers
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)
- Compostable plastics
- Paper containers, paper plates
- Napkins and paper towels
Things that don’t belong in the Mill food recycler 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 (Library tab) 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 rcity@mill.com.
What do I do with the organic material that can’t go in the Mill bin?
Organic material that R.City accepts but Mill does not (like large bones or food-soiled paper) can do directly in your R.City bucket for pickup.
How is the bin different from home composting devices?
Composting is a form of biological digestion that breaks down organic material and takes weeks or months, not hours or days. Be wary of any claims to the contrary. The food-recycling Mill isn’t a composting device. The Food Grounds that come out of the bin are still food, minus the water, bulk, odor, and ick. The Mill is designed to conserve all the potential in your kitchen scraps, not break them down, so they can have a second life.
How often will the bin need to be emptied?
The Mill bin shrinks down your food by 80% so it needs to be emptied very infrequently. For most families, it takes up to a month before the bin needs to be emptied.
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 food recycler. 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.
Can I keep my Food Grounds?
You’re welcome to keep your Food Grounds and use them for your chickens, or turn them into compost. For any Food Grounds or organic material that you don’t use, R.City will pick it up.
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 info@recycledcity.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 info@recycledcity.com.
Are there drop off sites where I can swap my buckets?
Unfortunately at this time we do not have any drop off sites.
Can I get compost back from R.City?
Yes! You can reach out directly to R.City at info@recycledcity.com to request a compost delivery.
How do I get a Farm Box from R.City?
R.City offers fresh produce delivered directly to your door. You can reach out directly to R.City at info@recycledcity.com to purchase a farm box service plan.
Pausing or canceling service temporarily
We are not currently offering temporary pausing or canceling of the service. If you choose to cancel your R.City + Mill service, please reach out to rcity@mill.com and our team will walk you through the steps to return your Mill food recycler and R.City bucket. If you decide to cancel, please contact Mill or R.City within 30 days to have your bin picked up for free.
Can I just buy the bin?
You may purchase the bin and R. City pickups separately and directly through R.City. If you subscribe to a $30+ monthly farm box, a bucket and monthly pickups are included with your farm box. You can do so at www.mill.com.
Moving to a new location within the service area
No problem! Just update your information in the app and contact R.City at info@recycledcity.com so your pickup date can be updated.
Tracking your impact with R.City + Mill
At this time, you will not receive any impact reports, but you can track your impact in the Mill app Impact tab. You will also be eligible to sign up for a Farm Box subscription that allows you to get local, fresh produce grown with the Food Grounds your household generates.
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.

Electricity
The Mill 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 rcity@mill.com.
Smell
Your bin should be completely odorless. If it isn’t, check out this article to help troubleshoot, or reach out to rcity@mill.com.
How often do I need to replace my charcoal odor filter and how much does it cost?
Charcoal refills are currently included for Mill subscriptions. Each refill lasts for a year plus, depending on use. So your kitchen never smells.
Noise
When the Mill 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.
