One of the most interesting ways the Twins achieved LEED certification was through its rain water collection system. Its Rain Water Recycle System was provided by Pentair and allows any rainwater that falls onto the grass to trickle down and be collected and purified by the system. The stadium has recycled over 680,000 gallons of rainwater, and is mainly used to clean the seating area for now. The Twins hope that they can use this recycled water to water the playing field in the future.
One of the most admirable efforts by the stadium is their ongoing effort to reduce food waste and help the community by donating any unused food to local charities. In one season, they donated over 7,500 tons of food, including hot dogs, hamburgers, and chicken breasts. All of the food was packaged but untouched and, of course, uneaten by baseball fans.
The ballpark earned its LEED certification from USGBC and was named "The Greenest Ball Park in America." In 2011 it became the first professional sports franchise to be awarded both LEED-Silver certification for New Construction as well as for Existing Buildings: Operations and Maintenance.
