Summary: Reduced TiO2 nanotube arrays (r-TNAs) have emerged as promising environmental materials for efficient treatment of persistent organic pollutants (POPs) resistant to conventional biological treatment. r-TNAs possess superior conductivity and solar light absorption, as well as well-organized open channel structures for efficient mass transfer. Additionally, r-TNAs can be grown directly on substrates without the use of adhesives, improving their durability and reusability. This paper provides a comprehensive review of r-TNAs in advanced oxidation processes (AOPs), including their fabrication techniques, appealing properties, and potential applications.

Summary: Sewage sludge is a dual-purpose by-product of wastewater treatment plants, serving as both a pollutant and a resource. Utilizing sewage sludge to produce biochar-based catalytic materials for water catalysis provides a novel approach for sludge reduction and resource utilization. These materials possess abundant raw materials, excellent pore structure, dispersed active sites, controllable surface chemical groups, and high specific surface area, making them widely applicable in advanced oxidation processes and catalysis fields. This paper describes the modification method for sludge biochar-based catalyst materials and explores the structure-activity relationship between the physical and chemical properties of these materials and their catalytic performance in water environments.

Summary: Different eco-friendly processes were studied to treat olive mill wastewater for the European 2024 zero-waste plan. The application of advanced oxidation processes, flocculation, and filtration proved to be effective in obtaining high-quality regenerated water. However, the increase in total iron content resulted in toxicity, which was resolved through subsequent flocculation and filtration steps. The optimized process achieved regenerated water suitable for irrigation with improved quality parameters.

Summary: The aim of this study is to design and optimize the process of functionalization of cellulose fibers using low-pressure microwave plasma discharge with hexamethyldisiloxane precursor to prepare a hydrophobic filler for composites with nonpolar thermoplastic matrices. The plasma treatment in oxygen process gas resulted in the functionalization of cellulose fibers without degradation, leading to highly hydrophobic cellulose with water contact angle up to 143 degrees. Treated cellulose allowed for a homogeneous mixture with polypropylene powder due to significantly lower agglomeration tendency of the functionalized fibers.

Summary: Environmental monitoring studies often miss a large portion of contaminants of emerging concern (CECs), but by analyzing archived samples from environmental specimen banks, new CECs can be identified. In this study, non-targeted high-resolution mass spectrometry was used to analyze white-tailed sea eagle muscle tissue samples collected over several decades. Through statistical analysis and molecular formula assignment, potential harmful compounds, including some of anthropogenic origin, were tentatively identified. This study demonstrates the feasibility of prioritizing new CECs in archived biological samples using univariate statistical approaches.

Summary: Organic micropollutants pose potential threats to environmental ecosystems and human health. This study investigated the uptake of perfluoroalkyl substances (PFASs), pharmaceuticals, and paraben by edible oyster mushrooms. The results showed a negative correlation between PFAS uptake and perfluorocarbon chain length. The presence of micropollutants had an impact on fungal colonization but did not affect the production of fruiting bodies in oyster mushrooms. The potential human risk from ingestion of micropollutants was evaluated based on acceptable daily intake (ADI).

Summary: This study examined the characteristics of anaerobic digestate based on food waste from three biogas plants in Sweden, including heavy metals, chemicals of emerging concern, and food-borne pathogens. The results showed that the concentrations of bacteria and heavy metals in the anaerobic digestate were below the maximum accepted levels, but spore-forming Bacillus cereus was present at high levels. The biofertilizers from different biogas plants had similar chemical profiles, which could help regulators establish priority lists of chemicals of top concern. Risk estimation indicated low environmental risks associated with the application of biofertilizers for food crop production.

Summary: This study focuses on the hygrothermal and mechanical properties of an insulating composite made from flax straw. Flax straw, an organic agricultural waste, has high moisture absorption capacity and low thermal conductivity due to its natural porosity. The research suggests that this material could be used in "green" construction, especially in rural areas, and liquid glass is proposed as a binder. The optimal composition of the filler, binder, and surface mapping were investigated, and the material exhibited low thermal conductivity and even binder distribution on the surface.
