While the Mariners may be struggling this season, Safeco Field is leading the way when it comes to the greening of ballparks and sports arenas across the country. According to a recent article, just six years ago, 88 percent of the waste created at a Mariners game was sent to the landfill. But by the 2011 season, Seattle had streamlined its ballpark operations to the point where they were using less than 10 million kWh a season and diverting 82% of their trash to Cedar Grove Composting, which processed 123.75 tons of the 259.47 total tons of refuse produced during the 2010 season. Another 88.8 tons was paper and plastic and commingled recycling.
The money saved by the Mariners is nothing to scoff at. A 30 percent reduction in electricity use has saved the Mariners an average of $302,900 per year since the 2008 season even though commercial electric rates in Seattle increased 22% during that span.
