Core to the new partnership is a Closed Loop Recycling Program through which the Philadelphia Union will work in conjunction with Braskem to promote the collection and recycling of polypropylene (PP) cups and caps used at the Talen Energy Stadium. The program is aimed at diverting thousands of pounds of PP cup usage annually at the stadium. Through the Closed Loop Recycling program, all plastic beverage cups sold in the stadium will be made of PP, which is fully recyclable and identified with the number "5" consumer recycling identification code. PP cups and caps will be collected at all events taking place at Talen Energy Stadium.
