More than 30 retailers that sell the E15 ethanol blend will be donating money to the National Breast Cancer Foundation in October. The retailers will donate 3 cents per gallon of E15 (15 percent ethanol) sold during the “Pretty in Pink” campaign. "As a breast cancer survivor, I encourage everyone to make a difference in someone's life by choosing to use E15 and reduce the cancer-causing pollutants in our environment. It’s easy, it’s simple, it can save the life of someone you love,” said Kathy Buckman Gibson, president of Buckman Laboratories International, which provides biofuels plants with technologies and tools to reduce energy and water use. See the list of participating retailers.
