A systematic review of plastic wastes as new adsorbents for dye removal in aqueous environments
AI summary Read the abstract
This review examined how plastic waste — particularly polyethylene terephthalate (PET) — can be repurposed as low-cost adsorbents to remove dyes from contaminated water, exploring how pH, temperature, and particle size affect adsorption efficiency. PET-derived carbon materials achieved a surface area of 2,530 m2/g and dye adsorption capacity of 2,874 mg/g, highlighting a circular economy approach to simultaneously addressing plastic waste and water pollution.
The harmful impact of plastic waste on various ecosystems has become a growing concern for researchers worldwide. Plastics can absorb different pollutants, and because they carry these contaminants, they increase ecological risks in aquatic environments. However, the ability of plastic waste to adsorb pollutants presents a valuable opportunity for water treatment. In this review, we explored several methods to synthesize carbon materials from plastic waste and assessed the effectiveness of recycled plastic as new adsorbents for removing dyes from water. We examined factors, such as salinity, pH, temperature, and physical–chemical properties, including particle size and surface area, to determine their effects on the dye adsorption efficiency of various plastics. Among the plastics analyzed, polyethylene terephthalate (PET) emerged as the most effective adsorbent, exhibiting a surface area of 2,530 m2/g and the highest dye adsorption capacity of 2,874 mg/g. This study emphasizes that adopting a circular economy approach by recycling plastic waste to effective adsorbents can help reduce environmental pollution and result in significant cost savings. This strategy minimizes the need for virgin raw materials and lowers waste management expenses, making water treatment processes more sustainable and economically efficient.

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
