If you're a fan of KRAFT String Cheese and Twists and you also like Six Flags Discovery Kingdom, TerraCycle Inc. may have a summer recycling program for you. KRAFT and TerraCycle have partnered with Six Flags parks across the United States to offer $15 discounts on general admission tickets to visitors who bring specially marked KRAFT cheese packaging to the park entrance any day through Oct. 10. The packaging will be sent to TerraCycle to be recycled into eco-friendly products.
