Description

Application

• Sustainable recycling of polyethylene terephthalate: Yang J. et al. discuss the recycling and upcycling of polyethylene terephthalate through biotic and abiotic pathways, focusing on sustainable practices that contribute to carbon neutrality. This research provides insights into environmentally friendly chemical processes that include the use of glycolic acid (Yang et al., 2024).
