Tips for a Successful Program

  • Sprinkle baking soda in compost cart and in your kitchen composter.
  • Store compost cart in the shade during warm weather.
  • Empty the contents of kitchen composter into your compost cart frequently.
  • Drain as much liquid as possible from food scraps before adding them to compost.
  • For extra-smelly food scraps, wrap in newspaper before placing in cart or put in the freezer until collection day.
  • Rinse out kitchen composter and compost cart before materials build up.
  • Spray inside of compost cart with a vinegar and water solution.
  • Drain as much liquid as possible from food scraps.
  • Place an opened paper yard-waste bag inside the compost cart to hold the food scraps.
  • Put a couple pieces of flattened cardboard (1-2 large pizza boxes are perfect) at the bottom of the compost cart before adding food scraps. This buffer allows the material to slide out more easily.
  • Place materials into a small paper bag and then into your compost cart. It is advised that food scraps be double bagged during the winter.
  • Wrap drippy wet items (e.g., coffee grounds, melon rinds) in 1-2 sheets of compostable paper towels before putting into the compost cart.
  • Rinse out carts, if temperatures allow, with non-toxic soap and water and empty onto your grass or gravel, never down the storm drain.  
  • Notify and educate staff before placing compost bins out for use.
  • Ensure indoor compost bins are clearly marked and easily distinguishable from other receptacles.
  • Place indoor trash, recycling, and compost bins directly next to one another.
  • Consider eliminating or cutting down on single-use items, such as condiment cups, straws, etc.
  • Replace single use items with reusable items, whenever possible. 
  • Ensure compostable and non-compostable products are easily distinguishable from one another.

Frequently Asked Questions

No.

No.

Yes, if they are paper/fiber items and on the list of allowed items. These are CMA-W certified items minus plastic, bamboo, and palm leaf products. Bioplastic, bamboo, and palm leaf products do not break down in our system in a timely manner.

No. They pose a real litter problem as they are light and blow around, especially when the plastic is shredded in the ​grinder. 

We strongly encourage liner-less kitchen composter use. If a liner is a must for a kitchen composter, an unlined paper one is recommended.​ For curbside carts, we recommend using ​a paper yard bag ​during the winter months​ to prevent materials from freezing to the cart.

Please contact WM Customer Experience at 866.797.9018 or by email at CustomerServiceCM_GLA@wm.com. Make sure to ask for the Great Lakes Public Sector team when calling, as they will have knowledge of the Ann Arbor commercial solid waste franchise agreement. 

Yes, it is true that some material is hauled to a compost facility in Wixom, MI that accepts those materials. However, for any services provided in the City of Ann Arbor, they must utilize the same guidelines as the city’s compost facility. Residents frequenting local businesses may bring items home to put in the residential compost cart, and that material does go to the city’s compost facility, so it must be in compliance with the acceptance standards for that site.
