Summary: In this study, the immobilization of anaerobic sludge in sodium alginate (SA) with polyaniline (PANI) nanoparticles (NPs) was found to enhance the degradation of organic matter in dairy wastewater (DWW) and increase biohydrogen yield. The concentration of PANI NPs in SA directly affected the degradation in DWW and bio-hydrogen production.

Summary: In this study, three types of hydrogel materials combining MagFePC with SA, PAA, and AG were prepared for the removal of antibiotics in simulated wastewater. MagFePC/SA hydrogels showed good toughness, abundant pores, and the best Fenton activity. They effectively removed antibiotics under neutral conditions without leaching of iron ions, thus causing no secondary pollution. The main active species for the degradation of antibiotics were identified, and the materials demonstrated good stability and reusability. Furthermore, a simple automated unit for wastewater treatment was developed, which achieved complete degradation of antibiotics.

Summary: Traditional wastewater treatments are expensive, so researchers have developed a cost-effective immobilized enzyme technology for wastewater treatment. By immobilizing a thermostable alkaline lipase, they were able to significantly reduce chemical oxygen demand (COD) and lipid content in the wastewater, demonstrating the potential value of immobilized lipase as an effective biocatalyst for wastewater hydrolysis.

Summary: This paper provides evidence for the potential application of sodium alginate as a curative and accelerator in the healing of skin wounds through a systematic review method. The evaluation shows that the improvement of mechanical properties can be achieved by correctly processing and crosslinking sodium alginate, but the increase of crosslinking may cause limitations in mechanical properties and hydrophilic behavior.

Summary: This study demonstrated the suitability of biodegradable complexing agents for treating soil contaminated with heavy metals using electrokinetic remediation. Sodium alginate (SA) significantly improved the removal efficiency of Cu2+ and Zn2+, while chitosan (CTS) could complex metal ions and form crosslinked CTS gelations, migrating to the catholyte under the electric field.

Summary: Finding alternatives to reduce plastic pollution is a major challenge in modern life. Biodegradable polymers derived from bio- and fossil-based sources have emerged as one potential solution. The biodegradation process is complex and influenced by various factors, making it important to understand the mechanisms involved. This review provides a comprehensive overview of this process, discussing the impact of enzymes, biofilms, CO2 evolution, and metabolic pathways. It also highlights the need for innovative approaches and interdisciplinary research to minimize plastic persistence in the environment.

Summary: This study demonstrates that photo-catalytic oxidation is a promising technique for treating simulated oily wastewater. Factors such as initial oil concentration, catalyst dose, stirring speed, pH value, and hydrogen peroxide dose were investigated for their impact on the degradation rate. It was found that the optimal operating parameters for oil removal were an initial oil concentration of 1 g/L, stirring speed of 850 rpm, pH of 8, 3 mL of hydrogen peroxide, and 1.5 g/L of titanium dioxide, resulting in a removal percentage of 98.43% after 40 minutes of irradiation. The application of these parameters to industrial oily wastewater resulted in a 99% oil removal rate after 40 minutes of reaction time with the addition of 3 mL of hydrogen peroxide.
