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.

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.
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.
Bag all trash. Keep all recycling materials loose.
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.
Curbside collection of organics will continue throughout the winter season with no suspension in service.
Here are some tips to reduce organic material from freezing to your curbside container:
Wait to put your organics container at the curb until 7 a.m. on your curbside collection day (if container is regularly stored indoors).
Line your container with cardboard or newspaper before placing wet yard waste or food waste in container.
Place food waste in paper bags or ASTM D6400-certified compostable bags before placing in container.
Place food waste in freezer to preserve material. You can place frozen food waste in container for your curbside collection day, or keep it frozen until temperatures warm up.
If you keep your container outdoors and regularly add food waste (or yard waste such as wet leaves) to it, the material may freeze to the container. This can cause the materials to not empty from the container during curbside pickup. Material will thaw and loosen from container when temperatures warm up again.
Curbside customers in Iowa City can receive either a 95-gallon or 25-gallon cart for organics (food waste and yard waste) curbside collection. Yard waste and food waste can be added to the same container for pickup.
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 Iowa City City Hall (410 E. Washington St.) during regular business hours, 8 a.m. to 5 p.m.
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 container.
To help keep this container clean, use newspaper, or ASTM D6400 or U.S. Composting Council 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.
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.
Table to Table is a local non-profit organization that rescues edible food and delivers it to organizations in Iowa City that can use it. Learn more about the organization and how to volunteer by visiting, www.table2table.org.
