Addressing the Sustainability Conundrums and Challenges within the Polymer Value Chain

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.
