University of Utah Dining Services has found the recipe for a greener campus by cooking up a comprehensive sustainability initiative that reduces food waste, boosts composting and recycling and sources ingredients from local and environmentally conscious suppliers.

Dining Services begins its sustainability efforts by actively partnering with companies that emphasize sustainable farming, ethical labor practices, and eco-friendly packaging. These values are reflected across the 10 dining locations and catering operations on campus.

“We work closely with our robust procurement teams to source our ingredients from reliable partners that align with our overall as well as campus goals of sustainability efforts,” said Ken Ohlinger, campus executive chef for Dining Services.

“We have a strong sustainability purchasing policy that includes sourcing fresh yogurt and milk that is free of artificial growth hormones, only sourcing certified humane cage-free eggs, seafood that is approved and adheres to the Monterey Bay Aquarium Seafood Watch, poultry raised and produced without the routine use of human antibiotics and more.”

To further cut emissions and support the regional economy, Dining Services increasingly sources ingredients from within Utah. Charlie’s Produce helps Dining Services buy from a variety of local farms and the campus dining team also works with Cherry Hill Farms, Bangerter Farms, Central Milling Co. and Slide Ridge Honey for flour and specialty items produced in the area. “We continuously rotate local farms based on seasonal items,” Ohlinger continued.

Wasatch Meats supplies halal chicken, specialty fish, and pork products, while Stone Ground Bakery and The Bagel Project deliver freshly baked goods to campus kitchens.

Once ingredients arrive, the culinary team maximizes their use through creative repurposing. Cheese trimmings go into mac and cheese sauces, raw produce becomes ready-made salads, and leftover bread is transformed into croutons or breadcrumbs.

“Some other examples of how we reuse products include reusing pineapple rinds into tepache as an aqua fresca in the dining halls and using our vegetable trimmings and chicken bones in stocks for many of our soup bases,” Ohlinger said.

Despite these efficiencies, operating large-scale food services still generates waste. To tackle this, Dining Services adopted WasteNot 2.0—a tracking program that allows kitchen managers to monitor and minimize daily food waste.

“This helps us track our waste daily and allows us to set targets to minimize the amount of waste we generate each day,” Ohlinger explained.

During a typical month of dining service at Urban Bytes at Kahlert Village, United Table at Heritage Center, Miller Cafe at Lassonde, Caroline’s Kitchen at Gardner Commons, the Food Court, Crimson View, the Epicenter Cafe, and within catering, Dining Services averages approximately 225 pounds of organic green waste per day—which includes trimmings and peelings of fruits and vegetables and items that can’t be repurposed such as bones, meat fats, onion peels, eggshells, etc.

Partnering with Momentum Recycling for the past eight years, Dining Services diverts compostable material from the dining halls to be composed in Park City or to Wasatch Resource Recovery to feed energy back into the power grid (some of that energy comes back to the U, while most of it goes to North Salt Lake).

Working with the U of U Facilities Team, campus dining also recycles cardboard and is looking into expanding recycling to glass and plastics.

In an effort to decrease the amount of red waste—avoidable overproduction and production waste—Dining Services offers made-to-order dishes ordered through a QR system called Tavlo. Wait times for items are displayed both on the app and on screens in the dining areas to help diners make decisions about what to eat at any moment in time.

“Students not only get the advantage of enjoying a fresh and customized made-to-order plate, but it also reduces our food waste by minimizing ingredients being used at a time,” said Ohlinger. “Rather than batch-cooking massive quantities of food and serving them on a buffet line, the QR code option allows dishes to be made on the spot, using only what is necessary, while delivering fresh, high-quality meals. We continually seek ways to minimize production waste and responsibly manage our resources.”

Students who need meals on the go can participate in the reusable “To-Go Box” program. By using one meal swipe, they can fill a green to-go container, enjoy their meal elsewhere, and return the box for a sanitized replacement or hold a virtual token for later use.

“They have 20 minutes to fill their container, and the box must be able to fully close,” Ohlinger said. “When students are ready for their next to-go meal, they can bring back their used empty container to exchange it for a new sanitized one, or they can collect a virtual token through the app to hang onto until they are ready for their next to-go meal.”

At the end of the day, Dining Services ensures that excess food supports those in need across the city. Some go to the U’s campus food pantry located in the Union, as well as the student-run Food Recovery Network, which connects with local food banks for food donations, as well as Waste Less Solutions, a local nonprofit organization that works with organizations to assist in repurposing food.

With each meal served, each scrap reused and every box recycled, U Dining Services is proving that sustainability can become part of the daily routine and be baked into every part of campus life—feeding both students and the planet.
