Abstract

Plastic waste pollution, including non-biodegradable landfills, leaching of toxic chemicals into soil and waterways, and emission of toxic gases into the atmosphere, is significantly affecting our environment. Conventional plastic waste recycling approaches generally produce lower value materials compared to the original plastic or recover inefficient heat energy. Lately, upcycling or the valorization approach has emerged as a sustainable solution to transform plastic waste into value-added products. In this review, we present an overview of recent advancements in plastic waste upcycling, such as vitrimerization, nanocomposite fabrication, additive manufacturing, catalytic transformation, and industrial biotechnology, envisaged with technical challenges, future developments, and new circular economy opportunities.

  • Recycling plastic waste to convert it into useful materials reduces the need for new resources and enhances the economic value of the waste.

    “Recycling plastic waste to convert it into useful materials is a more attractive strategy, as it not only reduces the need for new resources but also enhances the economic value of the waste [11].”

    From Transforming Plastic Waste into Value: A Review of Management Strategies and Innovative Applications in Sustainable Construction (2025) · cites this paper as [11]

    The Introduction (page unavailable) says recycling turns waste into useful products and upcycling creates products of higher value; the Conclusions likewise describe value-added products from plastic waste. But the paper distinguishes upcycling from conventional recycling, which it says generally yields lower-value materials, and it does not directly state that this strategy reduces the need for new resources.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
