Topic: Bioplastics and Microplastics: Mechanisms, Toxicity and Future Prospects

The global plastic crisis has triggered an urgent search for sustainable alternatives as conventional plastics persist in environmental pollution. Bioplastics, derived from renewable resources and distinguished by their biodegradability, have emerged as potential game-changers. However, the story of bioplastics is intricate, with concerns surrounding microplastic formation, potential toxicity, and their true environmental impact casting doubt on their promise. This Special Issue of Water Emerging Contaminants & Nanoplastics (WECN) delves deep into the complex world of bioplastics, shedding light on their mechanisms, toxicity, and future prospects.

We invite researchers and academics across diverse disciplines to submit original manuscripts that provide critical insights into various aspects of bioplastics, including:

● Bioplastics types and mechanisms: Explore the diverse range of bioplastics, from plant-based to bacterial polymers, and delve into their biodegradation pathways and environmental fate;

● Micro-/nanoplastic formation and release: Investigate the mechanisms by which bioplastics break down into microplastics, including fragmentation during use, composting, and wastewater treatment;

● Toxicity assessment: Evaluate the potential toxicological impacts of bioplastics and associated microplastics on human health and environmental ecosystems. This includes analyzing the leaching of chemicals, adsorption of pollutants, and potential effects on organisms;

● Life cycle analysis: Conduct comprehensive life cycle assessments of bioplastics, comparing their environmental footprint with conventional plastics across production, use, and disposal stages;

● Innovation and future directions: Explore cutting-edge advancements in bioplastics research, including bioplastics with enhanced biodegradability, improved functionalities, and strategies for mitigating microplastic release;

● Policy and economic considerations: Analyze the economic viability and policy frameworks needed to facilitate the widespread adoption and sustainable management of bioplastics.

By bringing together diverse perspectives and cutting-edge research, this Special Issue aims to address the critical questions surrounding bioplastics and inform their responsible development and implementation. A comprehensive understanding of their mechanisms, potential risks, and promising future directions is crucial for navigating the complex path towards a plastic-free future.

We encourage researchers and academics with expertise in bioplastics, biodegradation, microplastics, environmental toxicology, life cycle analysis, and related fields to submit their original manuscripts for consideration. We anticipate insightful contributions that will advance our understanding of bioplastics and shape their trajectory towards a truly sustainable future.
