Progress and Challenges in Polystyrene Recycling and Upcycling

The Cover Feature shows how chemistry, logistics, packaging design, law, policy and other factors affect the effectiveness and efficiency of plastic recycling. Converting PS waste into valuable chemicals can surpass the low-value approaches of producing fuel or regenerated plastics. In this illustration, the signposts highlight the important roles of “policy”, “design” and “logistics”. The world map underscores the urgent need for a joint global effort to address the plastic pollution crisis. More information can be found in the Research Article by G. Liu and co-workers.
