As the world celebrates the 30th anniversary of Earth Day on April 22, Anheuser-Busch Companies (A-B), the world's largest brewer, based in St. Louis, Mo., celebrates the 30th anniversary of its own environmental program: A Pledge & A Promise. The program, which began in 1970 when then-chairman August A. Busch, Jr. promised that Anheuser-Busch would use its resources to work for a quality environment, extends throughout all Anheuser-Busch operations and subsidiaries.Today, Chairman and CEO August A. Busch III has encouraged employees to remember -- both at work and at home -- that, "Our environmental philosophy is based on the belief that the world we all share is given to us in trust. Every choice we make regarding the earth, air, and water around us is made with the objective of preserving these resources for all generations to come."Recently released figures show that Anheuser-Busch employees have embraced the philosophy with open arms, as the following 1999 data indicate: A-B breweries recycled:Spent Grains 3.526 billion poundsGlass Cullet 83.7 million poundsCorrugated Cardboard 51.9 million poundsAluminum 3.8 million poundsScrap Metal 6.2 million poundsPlastic Strapping 1.6 million poundsOffice Paper 1.5 million poundsMiscellaneous materials 11.4 million pounds
