Summary: A microbial-driven approach is being used to treat, recycle, and manage pharmaceutical and personal care products (PPCPs) in order to mitigate water contamination. PPCPs are emerging contaminants that pose risks to ecosystems and human health. Bioremediation techniques using mixed cultures of bacteria, algae, and other microbes are effective in removing PPCPs from effluent.

Summary: In this study, torrefied wheat straw and oat hulls were combined with kaolinite and chitosan to obtain pelletized adsorbent materials. The composites were compared to spent coffee grounds as a reference biomass system. IR and C-13 NMR spectroscopy were used for structural characterization, and a cationic dye probe was employed to evaluate the adsorption properties. The results showed that crosslinking notably reduced the adsorption capacity for torrefied biomass composites, while greater uptake occurred for the spent coffee grounds composites. A cost-benefit analysis indicated that the torrefied wheat straw composites are competitive adsorbents per dollar material cost compared to the spent coffee grounds composites. Pelletized adsorbent technology with torrefied biomass offers lower chemical input costs and sustainability.

Summary: This paper presents a new method for Fenton treatment of complex wastewater using a novel bioelectrode system. The new system eliminates the need for additional dosing of Fe(II) and H2O2, prevents iron-sludge accumulation, and reduces consumption of pH regulators. The experimental results demonstrate that the method is efficient in removing dissolved organic carbon and specific recalcitrant organics.

Summary: Most households and healthcare facilities dispose of contaminated, unused, or expired medicines with municipal wastes. Different techniques are used for managing solid, semi-solid, and liquid pharmaceutical wastes, but their sustainability and ecofriendliness profiles are subjective and controversial. This comprehensive review aims to bridge the knowledge gaps in pharmaceutical waste management by objectively evaluating the techniques and proposing integration strategies to make the existing models sustainable, circular, and eco-friendly.

Summary: The increasing trend of industrialization leads to the release of industrial effluents. Waste water treatment is important for waste disposal and sustainability. Sustainable and energy efficient treatment methods are attractive, but existing technologies have sustainability issues. Conventional and advanced technologies are implemented for wide range of effluents, but secondary sludge generation is unaddressed. Biochar is effective for certain contaminants. Nanotechnology and membrane technology are promising for waste water treatment. Carbon nano structures, nano filters, graphene, and nano magnets are potential candidates.

Summary: Wastewater generated from various sources poses significant threats to the environment and human health. Conventional treatment methods are inefficient, while non-conventional bioremediation techniques offer cost-effective and eco-friendly solutions. Phycoremediation, utilizing algal diversity, shows promise in removing hazardous contaminants and producing value-added products. Future research should focus on developing and conserving hyperaccumulator microalgal strains to achieve sustainable wastewater treatment.

Summary: Nanofiltration is an effective method for removing emerging pharmaceuticals from waste-water to improve water quality and mitigate environmental impacts. However, the low separation efficiency of current nanofiltration membranes has hindered their development. In this study, a thin film composite membrane was prepared by stacking covalent organic framework (COF) nanosheets on a ceramic hollow fibre, showing high rejection for environmentally persistent pharmaceuticals. The COF-based nanofiltration membranes have a small footprint and can be easily integrated into existing water treatment systems, making them a promising option for mitigating the environmental impacts of emerging pharmaceuticals in wastewater.

Summary: An innovative approach involving direct sodium silicate-sodium hydroxide (Na2SiO3-NaOH) collaborative technology is proposed for the safe disposal of electrolytic manganese residue (EMR). This approach effectively treats EMR without hazardous effects using Na2SiO3 as the solidifying agent and NaOH as the activator. The study provides insights into the kinetics of Mn2+ leaching under the effect of Na2SiO3-NaOH and demonstrates the potential of this co-treatment technology for sustainable waste management.

Summary: For the first time, an integrated approach combining life cycle assessment (LCA) and life cycle cost (LCC) analysis was used to evaluate the performance of three wastewater treatment methods. The results showed that the trickling filter (TF) system was more cost-effective and the use of produced biogas led to significant reductions in toxicity potentials and ecosystem impact.
