Special Issue Information

Dear Colleagues,

Sustainable and environmentally friendly polymers are important not only for their performance during use but also for their synthesis, service life, and end-of-life management, including disposal and the risk of secondary pollution. Conventional polymer synthesis often relies on toxic solvents and high energy input and generates significant waste. In contrast, green chemistry approaches aim to reduce hazardous by-products while enabling innovative functional materials.

This Special Issue will highlight advances in biodegradable polymers, cyclodextrin-based nanosponges, nanostructured drug carriers, hybrid polymer–nanoparticle systems, and polymeric adsorbents prepared through solvent-free or low-waste processes. Particular emphasis will be placed on the regeneration and reuse of adsorbents through eco-friendly strategies, which are crucial for sustainability. Beyond developing high-capacity adsorbents, current research increasingly focuses on safer, more stable, and efficient materials, alongside effective regeneration methods to minimize consumption and secondary waste.

Conventional techniques, such as thermal or solvent-based desorption, have limitations in efficiency and by-product formation. Therefore, innovative alternatives—including deep eutectic solvents (DESs), supercritical CO2, and other green solvents—will be explored as enabling tools for polymer synthesis, processing, and regeneration.

By bringing together contributions from materials science, chemical engineering, and applied chemistry, this Special Issue aims to provide an interdisciplinary platform for innovations in sustainable polymer design and applications. Topics include environmental remediation, drug delivery, catalysis, energy-related materials, and industrial processes, highlighting the broad potential of sustainable polymers to advance both science and technology.

Biopolymer-based materials have gained significant attention as sustainable alternatives for wastewater treatment due to their biodegradability, low toxicity, and high adsorption potential. Despite extensive research on individual materials such as chitosan, cellulose, and alginate, a comprehensive synthesis of global research trends integrating multiple biopolymers remains limited. This study addresses this gap through a large-scale bibliometric analysis of 13,720 publications indexed in the Scopus database from 1995 to 2025. The dataset was systematically analysed using VOSviewer to evaluate publication trends, leading journals, countries, institutions, collaboration networks, and keyword co-occurrence patterns. The results reveal a rapid growth phase after 2016, driven by increasing global demand for sustainable water treatment technologies. China, India, and the United States emerged as the most productive and influential contributors. Keyword analysis highlights adsorption, wastewater treatment, cellulose, and chitosan as dominant research themes, with growing emphasis on composite materials and functional modifications. Beyond descriptive metrics, this study identifies key research gaps, including limited focus on scalability, regeneration efficiency, and real-world application of biopolymer-based systems. The findings provide a comprehensive understanding of the evolution and current direction of the field, offering strategic insights for future research and development of high-performance, sustainable wastewater treatment materials.
