A plastic that recycles itself

Recycling electronic gadgdets is really difficult because it is not easy to separate their plastic components and dangerous to burn them.
Now researchers have invented new plastics which can be degraded exposing them to ultraviolet light. These new plastics dissolve into a clear solution after this exposition. Their small components can be used again to make other plastics, therefore we generate less waste and we reduce raw materials.
Researchers have to check if the use of light influences the properties of plastics, for instance, their strength or durability.
