Other Organic Waste
- Shredded Paper and Paper Towels/Napkins are accepted in curbside composting and at the Iowa City Landfill's Compost Facility.
- Pumpkins and Gourds are accepted in curbside composting and at the Iowa City Landfill's Compost Facility. Remove any candles or lights from inside your pumpkins before composting.
- Natural, Unflocked Holiday Trees are accepted in curbside composting and at the Iowa City Landfill's Compost Facility. Remove all decorations first and do not place your tree in a plastic bag.
- Garlic Mustard is accepted in curbside composting and at the Iowa City Landfill's Compost Facility. Garlic Mustard is accepted at our facility because the compost reaches a high enough temperature. We do not recommend adding Garlic Mustard and other invasive species to a backyard compost pile.
- Pet Waste, while organic, is not accepted in curbside composting or at the Iowa City Landfill's Compost Facility. Please place pet waste in the regular trash.
Curbside customers in Iowa City can receive 25-gallon or 95-gallon carts for organics (food and yard waste) curbside collection by filling out a request form. Yard waste and food scraps can be added to the same container for pickup. The first cart is included in the monthly $3.50 service fee.
Residents are allowed additional carts at a cost of $3.50 per month per cart to cover the cost of the cart and service. Carts will be delivered based on availability and staff time. Wait times vary. Contact Resource Management at 319-356-5151 for more information.
If a customer determines that an additional cart that they had ordered is no longer needed, a pickup can be scheduled for January of the following year. The monthly cart fee will continue to be charged until that time.
Some customers may have received a second cart during the City’s initial delivery efforts. Effective July 1, 2021, these customers will be charged an additional $3.50 per month for the second cart. If the additional carts are no longer needed, please contact customer service at 319-356-5151 to schedule a pickup. This pickup will be scheduled as soon as possible.
Follow these guidelines to ensure successful and safe curbside collection.
- Place carts on a solid surface for pickup, such as the end of your driveway, or when snow is present, a cleared area of flat ground. Do not place carts on top of snowbanks.
- Do not overfill carts. City ordinance states the lids must be closed.
- Place carts at curb by 7 a.m. on your curbside day.
- Keep at least 3-feet clear zone around each cart.
- Face the arrows on cart lids to street.
- Return carts to your storage area at end of curbside day.
- Do not paint/write on carts.
- Do not remove the carts from home.
- Put carts at the curb only when full.
Curbside collection of organics continues throughout the winter season with no suspension in service.
Tips to reduce organic material from freezing to your curbside cart:
- Wait to put your cart at the curb until 7 a.m. on your curbside collection day (if cart is regularly stored indoors).
- Line your cart with cardboard or newspaper before placing wet yard waste or food waste in cart.
- Place food waste in paper bags or ASTM D6400-certified compostable bags before placing in cart.
- Place food waste in freezer to preserve material. You can place frozen food waste in cart for your curbside collection day, or keep it frozen until temperatures warm up.
If you keep your cart outdoors and regularly add food waste (or yard waste such as wet leaves) to it, the material may freeze to the cart. This can cause the materials to not empty from the cart during curbside pickup. Material will thaw and loosen when temperatures warm up again.
Iowa City curbside customers that would like a 2-gallon kitchen food scraps container can pick one up at the City Hall Cashier office in City Hall (410 E. Washington St.) during regular business hours, 8 a.m. to 5 p.m.
- A full list of accepted food materials may be found in the Curbside Composting Guide (or view the text-only version).
- These containers are not to be put at the curb. This container is for kitchen collection only. Materials collected can be emptied into your organics curbside cart.
- To help keep this container clean, use newspaper, or ASTM D6400 or certified-compostable bags to contain the food scraps.
Several options exist for residents wanting to compost at home. Residents can start a backyard compost pile, or for an indoor option, composting with worms is possible. Resources and more information for both of these methods are below.
Businesses are encouraged to check out the EPA’s Food Recovery Challenge for information on food waste reduction and rescue.
Organics hauling options for businesses:
Did you know that over 25 percent of what goes into the Iowa City Landfill is food waste? That’s approximately 34,000 tons of food each year, just in Johnson County.
When food waste ends up in the landfill, it produces a harmful greenhouse gas called methane that is over 20 times stronger than carbon dioxide. This can impact local air quality and climate change. Composting is a better alternative to landfilling, but it is best not to waste food in the first place.
When we throw away food, we also waste all the water, energy, and natural resources used to produce, package, and transport food from farm to plate. In addition, wasted food means wasted money.
