Review of polymer technologies for improving the recycling and upcycling efficiency of plastic waste.

Chemosphere, 2023
Human society has become increasingly reliant on plastic because it allows for convenient and sanitary living. However, recycling rates are currently low, which means that the majority of plastic waste ends up in landfills or the ocean.
