Managing Liquids and Grease for Summerset Restaurants
For restaurant operators along the Sturgis Road and Highway 79 corridor in Summerset, managing the back-of-house waste stream requires a balance between speed and precision. As the residential base grows and more apartments move into the Elk Creek Road area, the pressure to maintain a clean, odor-free loading dock increases. Utilizing a specialized organics hauler helps mitigate the common issues of dumpster overage charges and summer odor complaints from shared alley enclosures, provided the waste stream remains clean of prohibited materials.
While food waste composting is an efficient way to handle prep trim and plate scrapings, certain materials can compromise the integrity of the collection and the final compost product. Liquids and grease, in particular, require a different management path than the solids collected in your organic waste carts. Understanding the distinction between what goes in the cart and what stays out is essential for maintaining compliance with local standards and keeping your service costs predictable.
The short answer
The 32- or 64-gallon carts provided by Rapid City Compost are designed for solid food residuals. This includes prep trim, plate scrapings, coffee grounds, food-soiled paper, and fryer-adjacent solids like breading crumbs. However, heavy liquids such as soup, milk, sauce, and fryer oil must be excluded. Liquids increase the weight of the cart significantly without adding compostable value, and they create splashing hazards for drivers during the tipping process.
Grease and cooking oils are handled by specialized renderers, not composting haulers. If these liquids end up in an organics cart, they leak through the seals, attract pests, and can cause a load to exceed our contamination tolerance. To keep your kitchen running smoothly, ensure your staff knows that the organics cart is for solids only. You can find more detail on these distinctions in our guide on [measuring results](/guides/restaurants/summerset/measuring-results).
How the pickup works locally
Rapid City Compost operates a 15-minute drive from our home base to reach Summerset. Because we route through the I-90 corridor on the same days we service Black Hawk and Piedmont, we are able to offer consistent [pricing](/pricing) that aligns with our core Rapid City accounts. This bundled routing makes the service affordable for small commercial kitchens and schools in the Summerset central neighborhoods.
For most [restaurants](/industries/restaurants), we provide a weekly pickup cadence. The standard setup involves a 32- or 64-gallon wheeled cart placed at the back-of-house, often supplemented by a small prep-line caddy for easy access during busy shifts. On service days, our trucks access Summerset via I-90, ensuring timely collection without the premiums often associated with being outside Rapid City limits.
At each service, customers receive a scale-verified pickup receipt. This provides an accurate weight of the diverted material, which is useful for internal tracking. For those needing to demonstrate regulatory adherence, we provide a compliance letter on request, which helps businesses stay aligned with Rapid City Municipal Code 8.16.010 regarding the management of putrescible waste.

Common mistakes we see
The most frequent issue in restaurant organics programs is the 'soup problem.' When large volumes of liquid are poured into a cart, the load becomes excessively heavy and prone to leaking. We also frequently see grease traps being emptied into carts or used cooking oil being disposed of in the organics stream. These materials are contaminants that require a different disposal route. Our [contamination policy](/contamination-policy) allows for a maximum of 2% by weight; if a load exceeds this, we provide a photo and a coaching call to help your team adjust.
- Heavy liquids: Always drain soups, stocks, and sauces down the appropriate kitchen drain before putting the solids in the cart.
- Fryer Oil: Keep all liquid fats and oils in a separate rendering bin provided by an oil recycling company.
- Non-compostables: Plastic gloves, sauce packets, and plastic liners do not belong in the organics stream.
- Weight management: If a cart is too heavy for a single person to tilt and roll, it likely contains too much liquid or compacted wet waste.
Before you toss everything into the cart, consider if there are edible portions that could be diverted elsewhere. You can review our advice on [food donation first](/guides/restaurants/summerset/food-donation-first) to see if some of your surplus can be used more effectively before it becomes waste. If you are unsure of your current volumes, conducting a [waste audit](/guides/restaurants/summerset/waste-audit) is a practical first step.
What to do next
Improving your kitchen's waste management starts with clear communication. Ensure your staff understands [how it works](/how-it-works) and knows exactly where the liquids should go. Training prep cooks to drain solids and keep grease separate will prevent contamination issues and keep your service costs low. If you are currently using a different provider and are concerned about odor or missed pickups, you may find our guide on [switching haulers](/guides/restaurants/summerset/switching-haulers) helpful.
