Summary

This study investigated microplastic distribution in coral reef sediments and reef-building coral tissues, documenting plastic particle accumulation in a biodiversity hotspot. The findings reveal that microplastics concentrate in reef systems and are ingested by corals, potentially interfering with filter feeding and causing tissue inflammation.

Polymers

PET

This review outlines chemical recycling of PET to virgin PET or novel materials via depolymerization-repolymerization and direct conversion. Advanced catalysts and novel recycling processes offer environmental and economic advantages.
