Plastic Waste Upcycling: A Sustainable Solution for Waste Management, Product Development, and Circular Economy
AI summary Read the abstract
This review examined plastic waste upcycling as a sustainable alternative to conventional recycling, covering methods that transform plastic waste into value-added products and support circular economy goals while addressing environmental pollution.
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.

Recent advances in chemical recycling and upcycling of plastic waste into valuable materials, chemicals, and energy: a comprehensive review
AI summary Read the abstract
A comprehensive review cataloged advanced chemical recycling and upcycling pathways—including pyrolysis, gasification, hydrocracking, and solvolysis—capable of transforming mixed plastic waste streams into circular high-value chemicals, fuels, and energy carriers. These technologies are directly relevant to microplastic pollution research because scaling chemical recycling reduces the volume of plastic that degrades into environmental microplastics, addressing the problem at the source.
Value Addition and Up-Cycling of Plastic Waste: Technologies, Challenges and Sustainable Opportunities
AI summary Read the abstract
This review paper looks at new ways to turn plastic trash into valuable products—like fuel, building materials, and 3D-printing supplies—instead of just downgrading it into cheap, low-quality items like most recycling does today. This matters because less plastic waste sitting in landfills and oceans means less of it breaking down into microplastics that can end up in our water, food, and bodies. The authors note that combining these newer technologies with smart policies could help scale up these solutions, though challenges like contamination and cost still need to be worked out.
