Addressing the Sustainability Conundrums and Challenges within the Polymer Value Chain
AI summary Read the abstract
This review critically examines sustainability challenges across the polymer value chain, including misconceptions about biobased and biodegradable plastics. Researchers analyze the emergence of bioplastics, compare plastic products against their alternatives, and assess greenwashing in the fashion industry. The study highlights the growing importance of addressing microplastics contamination and urges the research community to scrutinize superficial sustainability claims.
Sustainability is a buzzword across numerous industries, and the polymer value chain is no exception. Due to the ubiquitous nature of polymer products, the conundrums and misconceptions revolving around them are universal too. In this review, we attempt to meticulously undertake some of the polymer-based sustainability conundrums and challenges, driven by technical knowledge and supported by facts. Four major topics of relevance are selected and reviewed without any bias. A basic understanding of all sustainability-related jargon is examined at the beginning to provide the necessary fundamental awareness. Thereafter, the emergence of biobased polymer products is critically analyzed against its distinct biodegradability conundrums. This is followed by an outlook and comparison of plastic products versus their alternatives. Greenwashing in the fashion industry is also reviewed in depth. Among the challenges, issues related to microplastics are assessed owing to their importance currently. It is critical that readers can understand the actual scenario and call out product propaganda with superficial claims. A meticulous overview of the existing literature and information is conducted to summarize all the conundrums, challenges, and future aspects. This examination of pertinent topics is carried out in the hope of spreading knowledge, enabling a higher critique within the polymer research community and a sustainable environment.

The hidden costs of biodegradable plastics: Environmental persistence, microplastic toxicity, and implications for sustainable development
AI summary Read the abstract
"Biodegradable" doesn't always mean it actually breaks down quickly in the real world, this review of existing research finds that many so-called eco-friendly plastics still break into tiny micro- and nanoplastic particles that can stick around in the environment for a long time. These particles have been linked to inflammation, hormone disruption, and cell damage in animals, meaning the "green" label on some products may be giving people false confidence about their safety and environmental impact.
Bioplastics and the environment: Solution or Green Illusion?
AI summary Read the abstract
This review critically evaluates whether bioplastics are genuinely environmentally friendly alternatives to conventional plastics, finding that many bioplastics degrade incompletely under real-world conditions, form persistent microplastic fragments, and may pose ecological risks comparable to conventional plastics.
