We are especially grateful for ABM's efforts to continually improve the efficiency of the day-to-day operation." - Mike Rock, Vice President, Ballpark Operations

Challenge

The Diamondbacks needed a partner with the expertise and staffing capacity to deliver consistent cleaning processes, including detail work, post-event cleaning, and pressure washing. The leadership team sought out a partner they could trust to deliver consistent janitorial services throughout the stadium and meet their high standards, so they could focus on strategic work instead of operational oversight.

The Diamondbacks also wanted to pursue forward-looking environmental programs aligned with MLB's sustainability focus and Arizona's desert conservation needs. Achieving these goals required a strategic, innovative partner offering stadium cleaning services in Arizona that could scale alongside ambitious environmental targets.

Solution

ABM implemented a comprehensive event-based janitorial strategy that addressed immediate operational needs while creating capacity for sustainability innovation.

ABM assumed full oversight responsibility, relieving client leadership of post-event cleaning management duties. The team established structured pre-event, event-time, and post-event cleaning processes with proper bowl-washing protocols. ABM also developed a scalable staffing model leveraging regional labor partnerships across three Phoenix venues, reinforcing its role as a trusted provider of arena cleaning services throughout the region.

Multi-year sustainability initiatives

With operational stability established, ABM partnered with the Diamondbacks to expand venue sustainability programs:

• Year 1: The Diamondbacks were the first MLB team to launch a reusable cups program. In partnership with the Diamondbacks and its food and beverage partner, ABM began with a pilot in the All You Can Eat Suites and Cantina Bar with the goal of expanding across the entire suite level.
• Year 2: ABM implemented a water conservation initiative across the stadium using a data-driven bowl washing strategy. The program relies on heat mapping and third-inning visual verification for targeted cleaning in high-use zones.
• Year 2: The team also launched a smart restroom technology program using the KOLO coreless paper system that ensures full roll depletion before replacement. ABM staff rely on automated alerts to keep restrooms properly stocked.
• Year 3: ABM worked with the Diamondbacks and its food and beverage partner to expand the stadium's recycling and waste diversion program by transitioning to grab-and-go aluminum beverages to increase recyclable volume. There is now a dedicated recycling pick in the seating bowl. Data is tracked through MLB's sustainability software platform. Looking ahead, ABM will begin sorting waste in the stadium.

Benefits

ABM's stable staffing model and improved post-event process execution have eliminated the operational oversight burden on Diamondbacks leadership. The ability to successfully manage 200+ events annually with 150-170 team members per event demonstrates scalable capacity ABM's cleaning services at Arizona's stadiums.

The Diamondbacks are assigning ABM project work that their in-house team would typically handle, with potential future opportunity for expanding scope.

Sustainability programs have delivered meaningful results:

• The water conservation program delivers significant impact in Arizona's desert climate. In the first month alone, the program resulted in 198,000 gallons of water saved and an approximately $2,500 reduction in costs.
• Smart restroom technology reduced paper waste to 8% (below the typical average of 15-20%).
• In two seasons, the reusable cup program has diverted over 42,000 single-use cups equaling 3,430 lbs. of waste from landfills. For the 2025 season, the return rate reached 82%.

“ABM has been a crucial asset to the success of our Ballpark Operations department. They’re collaborative, proactive, and handle their operations with excellence. One thing that really stands out to me is the authentic care that ABM has for all they do. We love being on their team and having them on ours." - Rae Ehmann, Diamondbacks Manager, Events Services

By assuming full cleaning oversight and delivering consistent event execution, ABM freed the Diamondbacks to pursue ambitious sustainability goals. The result is a model that other MLB venues can follow as the league increases its environmental focus.
