Plastic pollution has escalated into a critical global issue, with production soaring from 2 million metric tons in 1950 to 400.3 2022. The packaging industry alone accounts for nearly 44% of this production, predominantly utilizing polyethylene terephthalate (PET). Alarmingly, over 90% the approximately 1 PET bottles sold every minute end up landfills or oceans, where they can persist centuries. This highlights urgent need sustainable management and recycling solutions mitigate environmental impact waste. To better understand PET's behavior promote its within circular economy, we examined chemical physical properties, current strategies most effective methods available today. Advancing economy framework by closing industrial loops demonstrated benefits such as reduced landfill waste, minimized energy consumption, conserved raw resources. end, identified various based on R-imperatives (ranging 3R 10R), focusing latest approaches aimed at significantly reducing waste 2040. Additionally, comparison (including primary, secondary, tertiary, quaternary recycling, along concepts "zero-order" biological techniques) was envisaged. Particular attention paid heterogeneous catalytic glycolysis, which stands out rapid reaction time (20-60 min), high monomer yields (>90%), ease catalyst recovery reuse, lower costs, enhanced durability. Accordingly, use highly efficient oxide-based catalysts glycolytic degradation is underscored promising solution large-scale applications.

Plastic pollution is an ever-escalating issue with detrimental effects on both the environment and human health. breaks down into smaller pieces, depending size they are called macroplastics, microplastics (MPs), nanoplastics (NPs). Some of these particles can easily enter food chain causing toxicity to many plants animals. The extensive use synthetic polymers such as polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), terephthalate (PET) poses substantial environmental concerns due their degradation-resistant characteristics. One ways microorganisms address this by producing enzymes. This review examines recent advancements in enzymatic degradation commercial-grade pure polymers, including effectiveness enzymes laccases, proteases, cutinases, PETase, MHETase, governing mechanisms across various plastic categories. Bioinformatic tools multi-omics, molecular docking, enzyme mining particularly useful identifying unconventional biocatalysts plastic-degrading microbes a culture-independent manner.
