Special Issue Information

Dear Colleagues,

This Special Issue, Waste Supermaterials: Engineered Multifunctional Composites for Dual Water-Waste Solutions, will spotlight the latest advancements in the development of multifunctional composite materials derived from waste resources. It will focus on innovative strategies that transform waste into high-performance materials capable of addressing two of the most pressing global challenges: water purification and waste management.

We welcome original research and review articles that explore the design, synthesis, and application of waste-derived supermaterials with dual-functionality. Topics of interest include, but are not limited to, advanced adsorbents, photocatalysts, and membrane materials from industrial, agricultural, or municipal waste; smart composites for wastewater treatment; and circular economy approaches that link waste valorization with water treatment technologies.

By bringing together multidisciplinary research from materials science, environmental engineering, and sustainable chemistry, this Special Issue will provide a comprehensive platform for novel solutions that contribute to cleaner water and a cleaner planet.

We look forward to your valuable contributions, which will help us to shape the future of sustainable materials and integrated environmental solutions.

The impact of milling process parameters on the physicochemical properties of waste plum stones was investigated to enable their further utilization as a functional material. The experiments were conducted using a planetary ball mill, with variations in milling duration (1–3 h), the ball-to-powder ratio (bpr) (10:1 and 20:1), and the rotation speed (250 and 500 rpm). Transformations of material in a function of process parameters were assessed by XRD, FTIR, and SEM analysis, revealing differences in particle size distribution, functional group composition, and surface morphology. Optimization of milling process parameters was focused on promoting fine particle formation and surface activation without causing significant material degradation. The best result was achieved with the PS-M10 sample, processed at a speed of 500 rpm and a bpr of 20:1 during a short milling time of 1 h. The milled sample demonstrated promising potential for further applications, particularly for heavy metal ion (Pb2+ and Cu2+) removal from aqueous solutions through adsorption. Full article
