Design an Eco-Friendly Plastic Photodegrador

[totoykabute]

i was thinking of a good thesis topic involving enviro-friendly touch and i came up with this: plastic photodegrador! the concept was from the idea that plastic degrades easily in the ocean, so i am planning to design an equipment that will make plastics degrade fast. the design is somehow like a solar cooker (pls see the attached image).
the plastic will be cut into fine pieces before putting it in my photodegrador. i hope you got the concept.

but i am not satisfied with the design, will someone help me modify my design? or is there any problem with my design? comments are badly needed. thank you!

Didn't get idea of your design.
Do you mean particular types of plastic, to test, whether it will degrade in open ocean environment?
