Driven by escalating environmental concerns associated with polyethylene terephthalate (PET) waste accumulation, this review explores its chemical upcycling into metal-organic frameworks (MOFs). Upcycling of PET waste into MOFs is an effective solution, because MOFs are promising materials for various applications due to their tunable functionality, high surface area and adjustable porosity. This paper reviews different synthetic strategies that have been used to prepare PET-derived MOFs and stresses incorporation of principles of sustainable chemistry into the transformation to reduce environmental impacts. This review also presents a comparative analysis of PET-derived MOFs and conventionally synthesized MOFs in applications such as adsorption, catalysis and gas storage. The review evaluates the sustainability of this method in terms of the environment, and type of development needed to make it more feasible to scale-up and implement in industries. By highlighting the possibility of sustainable conversion of waste PET into MOFs, this review promotes the innovations in recycling equipment, enabling both waste reduction and the design of novel materials.
