Depolymerization to Decontamination: Transforming PET Waste into Tailored MOFs for Advanced Pollutant Adsorption
AI summary Read the abstract
This review examines how PET plastic waste can be chemically depolymerized into building blocks — terephthalic acid and ethylene glycol — then used to synthesize metal-organic frameworks (MOFs) for removing heavy metals, dyes, and emerging contaminants from wastewater, simultaneously addressing plastic pollution and water purification through a circular economy approach.
Plastic waste and water pollution demand circular economy-driven innovations. This review examines metal–organic framework (MOF) synthesis from polyethylene terephthalate (PET) waste for wastewater treatment. Depolymerized PET yields terephthalic acid and ethylene glycol—essential MOF precursors. We evaluate the following: (1) PET depolymerization (hydrolysis, glycolysis, ammonolysis) for monomer recovery efficiency; (2) MOF synthesis (solvothermal, microwave, mechanochemical) using PET-derived linkers; (3) performance in adsorbing heavy metals, dyes, and emerging contaminants. PET-based MOFs match or exceed commercial adsorbents in pollutant removal while lowering costs. Their tunable porosity and surface chemistry enhance selectivity and capacity. By converting waste plastics into functional materials, this strategy tackles dual challenges: diverting PET from landfills and purifying water. The review underscores the environmental and economic benefits of waste-sourced MOFs, proposing scalable routes for sustainable water remediation aligned with zero-waste goals.

Valorization of PET Waste Into Advanced Adsorbents for Pollutant Removal From Wastewater: A Review
AI summary Read the abstract
Scientists are turning plastic water bottles into powerful filters that soak up harmful pollutants—like pharmaceutical residues, hormone-disrupting chemicals, dyes, pesticides, and heavy metals—from contaminated water. This review paper summarizes existing research showing that instead of letting PET plastic waste pile up in landfills and oceans (where it can break down into microplastics), we can transform it into materials that actually clean up our water supply. This matters because it tackles two health concerns at once: reducing plastic pollution that ends up as microplastics in our environment, while also creating better tools to remove other danger
Metal-organic frameworks and plastic: an emerging synergic partnership
AI summary Read the abstract
This review examines how metal-organic frameworks (MOFs), a class of crystalline nanoporous materials, can be used to address plastic pollution in water. Researchers found that MOFs show promise as adsorbents for removing micro- and nanoplastic particles, especially when integrated into composite materials or membranes, achieving high removal efficiency and water flow rates. The study also highlights an emerging trend of producing MOFs from plastic waste like PET as a sustainable source of raw materials.

Researchers developed a process to synthesise metal-organic frameworks (MOFs) from waste PET plastic as a cost-effective feedstock for MOF-based water treatment materials, aiming to address both the low recycling rate of waste PET in countries like South Africa and the high production costs that limit MOF implementation.
Unlocking the Potential of MOFs for Waste Plastic Resource Utilization and Microplastic Pollution Control
AI summary Read the abstract
This review examines the potential of metal-organic frameworks (MOFs) — a class of highly porous, engineered materials — to serve as catalysts for both breaking down microplastic pollution and converting waste plastic into valuable chemical feedstocks. MOFs offer tunable structures and large surface areas that make them attractive for both degradation and upcycling applications. The review positions MOF-enabled catalysis as a tool for transitioning toward a circular plastics economy where waste plastic becomes a resource rather than a pollutant.
Beyond Disposal: Unleashing the Potential of Plastic and Metal Waste in Producing Metal Organic Frameworks (MOFs) for Environmental Revitalization
AI summary Read the abstract
Scientists are turning plastic bottle waste and toxic metal waste (like battery scraps and industrial sludge) into useful materials called MOFs — sponge-like structures that can filter pollutants out of water and soil. This matters because it tackles two big environmental problems at once: reducing plastic pollution that breaks down into microplastics, and safely reusing hazardous heavy metals instead of letting them contaminate our water supply. This is a review paper summarizing existing research on how these waste materials can be converted into pollution-fighting tools, rather than reporting new lab results.
