The grass isn’t the only thing that’s green at Safeco Field.
The Mariners have made a long-term commitment to sustainability, making Safeco Field one of the greenest ballparks in baseball.
The Mariners have increased the recycling rate for Safeco Field from 13% in 2006 to almost 87% in 2015.
Safeco Field has been recycling compostables since 2007, resulting in the diversion of 9.4 million pounds of food and yard waste from the landfill. The food scraps and grass clippings are mingled with organic matter collected from businesses, restaurants, and homeowners across the greater Seattle area and transformed by Cedar Grove into compost that is prized by gardeners across the Northwest.
On Tuesday, the first 5,000 fans leaving the game against the Houston Astros game will receive nine-quart bags of official Safeco Field soil, courtesy of Cedar Grove Compost.
Safeco Field Sustainability
Safeco Field is one of the most sustainably operated facilities in the world. Almost 87% of all waste generated at the ballpark was recycled or composted last year, diverting almost 3,000,000 pounds of recyclable material from the waste stream.
Every year since 2010, the Mariners have been honored by Major League Baseball as American League Recycling Champions.
Additionally, Safeco Field has the lowest “energy intensity” of any ballpark in Major League Baseball. Energy intensity is a measure of a facility’s energy efficiency. In 2015, the Mariners became the first MLB team to install LED lights to illuminate the playing field. The LED lights use 60%-70% less energy than old-technology metal halide lamps.
