The Dr Pepper Snapple Group has teamed up with actors Woody Harrelson and Edward Norton to improve wastewater treatment at its bottling plant in Houston. The beverage-maker bought an on-site processing system from Baswood, a company that Harrelson founded and Norton chairs, in a bid to reduce costs and pollution. "This was a clear opportunity to reduce the costs associated with treating our wastewater," said Tim Gratto, vice president of sustainability at DPS. "But as with many decisions that are cost-driven, installing this system had clear environmental benefits."
