CLEAN : Scientists to harness the sun to break down plastic

The video discusses a process to convert ocean-polluting plastics into useful chemicals using sunlight, aiming for a renewable method. Challenges include scaling up, requiring more manpower and funding, and recovering catalysts without extra energy. A proposed system could be used in water treatment plants, utilizing sunlight to process plastics over several days.

What is the ultimate goal of the process being discussed in the text?

Describe the envisioned setup for the system in relation to water treatment or waste treatment plants.
