Summary: This study presents an integrated approach for the complete utilization of pepper sauce waste (PSW), extracting valuable by-products and ingredients while minimizing environmental hazards. Through laboratory and pilot-scale extraction processes, various valuable by-products including hot red pepper oil, no-heat pepper residue, no-heat red pepper oil, capsaicinoids, and capsaicin were obtained. Optimal processing and isolation conditions were determined for maximum utilization of the waste materials.

Summary: This study investigated the potential of developing biocomposites using a combination of poly lactic acid, polybutylene adipate terephthalate, and micro cellulose from different agricultural residues to produce biodegradable kitchenware suitable for food serving and other culinary applications. The results showed that the developed kitchenware exhibited desirable physical properties and biodegradability, providing an effective solution to environmental issues caused by single-use non-biodegradable plastic-based kitchenware.

Summary: In this study, a non-activated carbon derived from waste yerba mate was used as a matrix for the development of a carbon-sulfur composite cathode. The composite showed a remarkable initial capacity and high reversible capacity at a low charge/discharge rate. It also demonstrated good rate capability even when subjected to an increased C-rate during long cycling.

Summary: We analyzed textile fiber waste as a potential material to produce multilayer cotton fiber biocomposite. The properties of the products were superior to current particleboards and fiberboards in terms of strength and water resistance. We found that the four-layer waste cotton fiber composite had the best overall performance, with a dense structure and enhanced hardness and stiffness. The use of waste cotton fiber to prepare biocomposite with desirable properties is feasible and has potential applications in various industries.

Summary: Bio-based composites, including hemp shives, corncob, sawdust, are potential materials for insulation. This research examined the properties of new composite materials made of sawdust, corncobs, styrofoam granules, lime, and gypsum. The best composite material for thermal and sound insulation was found to be a 5 cm thick biocomposite composed of ground corncobs, styrofoam, lime, and gypsum.

Summary: This study investigated the synergy between industrial waste sulfur and urban waste waste cooking oil to enhance sustainability of the built environment. By binding sulfur to hydrocarbon derivatives in waste cooking oil, improvements in bitumen performance properties were achieved. Computational modeling and spectroscopic analysis confirmed the formation of sulfur-carbon bonds within the bitumen matrix, leading to enhanced rheological properties.

Summary: According to the waste hierarchy, waste prevention is better for the environment than recycling or recovery. However, the evaluation of waste prevention strategies is hindered by limitations. This study developed a systematic approach combining material flow analysis and life cycle assessment to assess the environmental impact of waste prevention activities and identified factors crucial to the evaluation. The approach revealed potential for improvement in waste prevention scenarios, such as reusing clothing locally and implementing take-back schemes for furniture.

Summary: The accumulation of petroleum-based plastic waste is a growing environmental concern. This study developed an effective plastic waste recycling scheme by creating ABS/paper biocomposites using waste ABS plastics and paper, with the addition of calcium carbonate to improve material properties. The experimental results showed that ABS/paper (CaCO3) 4:6 exhibited high mechanical strength, while ABS/paper (CaCO3) 7:3 had low water absorption. The study found that high-temperature melted ABS effectively filled the voids in the cellulose and the addition of calcium carbonate enhanced the flame retardancy of the material.

Summary: Modern technology allows for the extraction of nanocellulose from plant-based fibers, and its application in sustainable materials is a growing trend. While water is typically detrimental to nanocellulose-based materials, it plays an important role in plants, and many nanocellulose applications already incorporate or rely on water. This review presents a comprehensive assessment of the interaction between nanocellulose and water, covering various research areas such as physical chemistry, chemical modification, materials applications, and analytical methods.

Summary: In this study, a simple spray technique was introduced to prepare a superhydrophobic surface using rGO with Ni-S system (rGO-Ni) by using NiSO4 catalyst under microwave irradiation. The addition of nickel to rGO produced a quasi-periodic spike structure, increasing the superhydrophobicity of the coated glass. It is emphasized that the proposed simple spray coating using rGO-Ni provides a more favorable option for industry application in obtaining superhydrophobic surfaces.
