This summer, you can help clean up the environment while your family cleans up with savings and fun at Six Flags amusement park. Polly-O String Cheese and Twists along with the recycling company, TerraCycle, Inc., have partnered with Six Flags Theme Parks for a summer recycling drive that can earn you big discounts on admission prices.| At the Baltimore-area Six Flags, at 13710 Central Ave. in Upper Marlboro, you can participate in the program by taking specially marked Polly-O String Cheese and Twists packaging to the park entrance. Through Oct. 10, 2011, each specially marked Polly-O package is good for one free Kid’s Ticket (for children under 10 years old) with the purchase of a general admission ticket on weekdays, or for $15 off a general admission on any day of the week.. The park collects the packaging, which is otherwise either non-recyclable or hard to recycle, and sends it to TerraCycle, where it is converted into a wide range of products and materials. This summer’s recycling/discount program is available at the Baltimore-area Six Flags as well as Six Flags locations in Atlanta, Springfield, Mass., Jackson, N.J., and Lake George, N.Y.
