Earth Day Weekend - one of the greenest clubs in major league baseball teams up with BASF, The Chemical Company, to inspire its fans to follow its lead and start striking out landfills at home. Well on their way to batting 1.000 in their zero-waste program, the Seattle Mariners currently divert more than 80 percent of their waste stream away from landfills into composting and recycling centers.

The Saturday, April 21 Mariners-Chicago White Sox matchup marks the launch of “Sustainable Saturdays, a season-long program at Safeco Field to promote the kind of environmentally-conscious practices that have earned the club the prized position of number one in energy efficiency and number two in recycling in Major League Baseball.

The first 10,000 fans to arrive at the ballpark on Earth Day Weekend will receive a free “Kitchen Catcher” compost kit, compliments of BASF, Ecosafe, and Seattle Public Utilities (SPU). Inside are five compostable bags produced with BASF’s Ecovio® biodegradable polymers.

This weekend’s game also marks the launch of the BASF Kid Compost Trivia game where fans compete for a chance to win an Amazon Kindle Fire and appear live on the centerfield video board at the end of the seventh inning.

“When we realized that the bulk of what we were sending to the landfill was organic matter, the answer was obvious,” says Scott Jenkins, Vice President of Ballpark Operations for the Seattle Mariners. “Turn it back into topsoil. Our zero-waste program has gone from batting .120 just five years ago to .810 today. To help fans follow our lead this Earth Day Weekend, we’re giving away 10,000 kitchen compost kits including everything they need to get going. With the help of our fans, we aim to make 2012 the most sustainable Mariners’ season ever.”

The Kitchen Catcher will include a countertop container, five Ecosafe compostable liners, SPU coupons for Cedar Grove compost and savings towards the purchase of Ecosafe bags -- plus simple steps to help fans follow the team’s green lead.
