The presence of pharmaceuticals or their active metabolites in receiving waters is a sign of the inefficient removal of bioactive substrates from wastewater. Adsorption seems to be the most effective and inexpensive method of their removal. Waste management aimed at sorbents is a promising way to sustain several sustainable development goals.

The application of waste-derived highly efficient adsorbent for organic pollutants removal from water and wastewater is presented. Highly porous carbon beads with radially aligned macrochannels were prepared from asphaltene. Well-ordered inwardly aligned macrovoids favored solute diffusion and maximized the liquid accommodation capacity.

Introduction: Biochar utilization for adsorption seems to be the most cost-effective, easy/fast approach for pollutants removal from water and wastewater. Due to the high adsorption properties, magnetic biochar proved to be efficient in the sorption of heavy metals and nutrients. Although there are several studies on development of magnetic biochars, there is a lack of research on development of high-performance magnetic biochar from food waste for removal applications.

The COVID-19 pandemic is the largest global public health outbreak in the 21st century so far. Based on World Health Organization reports, the main source of SARS-CoV-2 infection is transmission of droplets released when an infected person coughs, sneezes, or exhales. Viral particles can remain in the air and on the surfaces for a long time.

Hierarchically porous piezoelectric polymer nanofibers are prepared through precise control over the thermodynamics and kinetics of liquid-liquid phase separation of nonsolvent (water) in poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) solution. Hierarchy is achieved by fabricating fibers with pores only on the surface of the fiber, or pores only inside the fiber with a closed surface, or pores that are homogeneously distributed in both the volume and surface of the nanofiber. For the fabrication of hierarchically porous nanofibers, guidelines are formulated.

In a circular economy model the way we use the textiles needs to change at a fundamental level. A circular economy is an alternative to a traditional economy (fabrication, use and dispose) in which we keep resources in a loop for as much time as possible, try to maintain their value while in use, and repurpose for generation of new products at the end of utilization. The value of the global fashion industry is 3000 Billion dollars that accounts for more than 2% of the world's Gross Domestic Product (GDP) (https://fashionunited.

The development of high performance, sustainable and inexpensive catalyst for environmental applications is a highly innovative and promising approach to meet the increasing demands from society on water treatment and pollution remediation. Carbon microtube (CMT) synthesized from cotton waste was successfully developed by direct pyrolysis of cotton bundle in argon atmosphere in different carbonization temperature (900, 1100, 1300 and 1500 °C). Carbon microtubes have been used for removal of Bisphenol A (BPA) in wastewater and showed the optimum performance for CMT11 and CMT 13.

In this research, the mechanical properties and microstructure of Al-15 wt % TiC composite samples prepared by spark plasma, microwave, and conventional sintering were investigated. The sintering process was performed by the speak plasma sintering (SPS) technique, microwave and conventional furnaces at 400 °C, 600 °C, and 700 °C, respectively. The results showed that sintered samples by SPS have the highest relative density (99% of theoretical density), bending strength (291 ± 12 MPa), and hardness (253 ± 23 HV).
