An interesting article showcasing the efficient and cost efficient degradation of polystyrene which reached a production level of 15.4 micro tons in 2022 and is continuously increasing. Globally 33% of material waste deposited in landfills contains polystyrene and only 1% is recycled. This recycling method could be highly beneficial by producing  monomeric benzoyl products that can be used as starting materials in chemical processes as well as some short polymer chains. In addition, a useful side reaction during the degradation process is the production of hydrogen.
