ClearA focused review on recycling and hydrolysis techniques of polyethylene terephthalate
This review examines techniques for recycling polyethylene terephthalate (PET), one of the most common plastics found as microplastic pollution. Chemical recycling through hydrolysis shows the most promise for breaking PET back into its original building blocks for reuse. Improving PET recycling is important because reducing plastic waste at the source is one of the most effective ways to decrease microplastic contamination in the environment.
