Ways to Prepare Compost for Collection
Optional Compost Carts
The city sells optional carts for compost collection. The city accepts a wide range of materials inside compost carts: plate scrapings (including meat and bones), fruit and vegetable waste, paper napkins, uncoated paper plates, paper cups, leaves, and grass clippings. Compostable material does not need to be bagged or bundled inside the cart.
To compost during the winter, place a layer of leaves (or newspapers/a pizza box) at the bottom of the cart and add coffee grounds, banana peels, etc. Periodically cover the vegetative food scraps with leaves or an inch of dirt to eliminate fruit flies and odors. Roll cart to the curb in April, when the compost season resumes for the growing season.
30-gallon Paper Bags
Place yard debris in large paper bags, available from local retailers. Each paper bag may weigh up to 50 pounds. Plastic bags are not accepted for storing compostable material.
Brush and branches up to 6 inches in diameter and 4 feet long may be tied with natural twine into bundles up to 18 inches in diameter and 50 pounds per bundle.
Yard waste drop off is available at the City of Ann Arbor Compost Center located at 4150 Platt Road, open Monday thru Friday, from 8 a.m. to 4 p.m.
In order to drop off yard waste, a valid City of Ann Arbor driver’s license or recent water bill is required. The yard waste limit per day is 6 bushels (1 cubic yard) per household. Residents must visit the scalehouse at the Materials Recovery Facility before and after dropping off their yard waste in order to verify material weights. A map is attached with this letter for reference.
City landlords, owners of multiple single-family properties and businesses are not eligible for the residential yard waste drop off program. These entities, for a fee, may drop off yard waste at the City of Ann Arbor Compost Center or the Recycle Ann Arbor Drop-Off Station.
Compost and mulch
Free compost or mulch: Apr. 15 - July 4 or while supplies last. Residents drive to the scale house at 4150 Platt Road and provide proof of Ann Arbor city residency — a recent water bill or driver's license. The scale house operator will then direct residents to the location of the free compost and mulch. Limit is 6 bushels (or 1 cubic yard) per household of compost, mulch, or any combination thereof per year. Residents must bring their own shovel and containers.
