Managing Liquids and Grease in Box Elder Apartment Composting

As the residential landscape along Liberty Boulevard and near Ellsworth Air Force Base continues to expand, apartment managers are facing increased pressure to manage waste volumes efficiently. In high-density housing, the shared trash room is often the primary source of resident complaints regarding odors and pests. Implementing a structured organics program helps mitigate these issues, but it requires a clear understanding of what a composting cart can and cannot handle. While resident kitchen scraps and coffee grounds are ideal for diversion, the introduction of heavy liquids and grease can quickly compromise the system.
Rapid City Compost provides specialized hauling for [Box Elder](https://rapidcitycompost.com/service-areas/box-elder) apartment communities, focusing on solid food waste and food-soiled paper. However, the success of a collection program depends on keeping the material dry and solid. When liquids like soups, milk, or fryer oil enter the organics stream, they increase the weight of the cart without adding value to the compost process, often leading to leaks and hygiene issues in shared enclosures.
Why this comes up here
The rapid growth of [apartments in Box Elder](https://rapidcitycompost.com/industries/apartments) means many residents are new to the area or new to the concept of separating food waste. In an apartment setting, the 'out of sight, out of mind' mentality can lead to residents pouring liquid leftovers directly into the organics cart. This is particularly common with items like expired milk, cereal milk, or large pots of soup. Unlike a backyard pile, a commercial organics cart is designed for specific moisture levels.
Liquids create three primary problems in the Black Hills climate. First, they dramatically increase the weight of the 64- or 96-gallon carts, which can lead to mechanical strain during pickup. Second, excess moisture accelerates the breakdown of solids in a way that produces foul odors, which is a significant concern for managers trying to avoid a public nuisance designation under Rapid City Municipal Code 8.16.010. Third, liquids seep into the bottom of the bin, making it difficult to empty completely and creating a sludge that attracts flies and other pests.
Setting the bins up right
Prevention starts at the resident's kitchen counter. We provide countertop caddies to residents, which act as the first line of defense. Managers should instruct residents to drain all liquids down the sink before placing solid scraps into the caddy. For example, a resident clearing a plate of pasta should strain the remaining sauce or water. If the material is too liquid to be picked up with a fork, it likely does not belong in the organics bin.
- Provide clear signage in the shared trash room showing 'No Liquids' or 'Drain Before Tossing'.
- Encourage residents to use food-soiled paper towels or pizza boxes at the bottom of their caddies to absorb incidental moisture.
- Ensure the shared 64- or 96-gallon cart is kept in a shaded, level area of the trash enclosure to prevent heat-related fermentation.
- Schedule a [waste audit](https://rapidcitycompost.com/guides/apartments/box-elder/waste-audit) to identify which buildings or floors are struggling with liquid contamination.
Grease and fryer oil require an entirely separate path. Fats, oils, and grease (FOG) should never enter the organics cart or the municipal sewer system. These materials do not compost in the same timeframe as fruit peels and coffee grounds, and they coat other organic materials, preventing the oxygen flow necessary for decomposition. Most apartment communities should have a designated grease collection point if they have high resident turnover or communal cooking areas.
Keeping the load clean
Our [contamination policy](https://rapidcitycompost.com/contamination-policy) is strict but fair: we allow for a 2% margin by weight. This weight-based threshold is easily crossed if a resident dumps a gallon of spoiled soup into a cart. When a load exceeds this limit, we provide a photo and a note to the site manager. This is not meant to be punitive but serves as a coaching tool to help you identify which residents need further training on the [how it works](https://rapidcitycompost.com/how-it-works) page of our site.
Managing grease is a matter of resident education. Providing residents with small, heat-resistant containers for bacon grease or cooking oil can prevent them from pouring these substances into the organics bin or down the drain. Once these containers are full and the grease has solidified, they should be disposed of in the regular trash, not the compost, unless a specialized yellow grease hauler is contracted for the site.
What changes after the first month
The first thirty days of an organics program are a learning period. Initially, you might see higher contamination rates as residents test the boundaries of the new bins. After the first month, the 'ick factor' typically decreases as residents realize that a dry organics bin is less offensive than a wet one. You will notice that the trash room stays cleaner and the heavy, putrid smell associated with rotting food in large compactors begins to dissipate.
