“…Hydrochar has environmental applications as a soil amendment (Bargmann et al, 2014;Khosravi et al, 2022) and as a nutrient source (Becker et al, 2019;Fei et al, 2019). The physical and energetic properties of hydrochar make it suitable for use as a solid fuel (Marin-Batista et al, 2020;Ipiales et al, 2022), enhancer of anaerobic digestion (Kumar et al, 2021), CO 2 capture agent (Goel et al, 2021;Wang et al, 2021a), energy storage material in fuel cells, supercapacitors, and batteries (Arenas Esteban et al, 2020;Zhou et al, 2021;Arauzo et al, 2022), and as a precursor for adsorbents (Diaz et al, 2019;Román et al, 2020) and activated carbons (Belete et al, 2021;Kumar et al, 2020). The use of hydrochar as a solid biofuel is acquiring focus because 50-85 % of its energy is contained in the feedstock (Román et al, 2012;Ipiales et al, 2021).…”

“…The monolayer sorption capacity of P. nidulans (CB14) for that drug was 0.6157 mg/g. Among used models similar adsorption prediction accuracy (Langmuir > Freundlich > Redlich-Peterson) was obtained by Román et al [ 57 ], who also conducted research about ring structure pharmaceuticals sorption onto derived from nature sorbents.…”

Purpose Cytostatic drugs cannot be easily removed by conventional sewage treatment plants, resulting in their ultimate release into aquatic systems where they become a threat. Thus, new technologies which can be used to eliminate these drugs more effectively before they enter the environment are increasingly important. Fungal treatment of wastewaters is a promising and environmentally friendly technology for pharmaceutical remediation. The aim of this work is to examine the biosorption of two cytostatics, bleomycin and vincristine, in the aqueous solution by fungal biomass. Methods Five white-rot fungi were used in this study: Fomes fomentarius (CB13), Hypholoma fasciculare (CB15), Phyllotopsis nidulans (CB14), Pleurotus ostreatus (BWPH), and Trametes versicolor (CB8). Tests were conducted on different types of biomass (alive and dead – autoclaved) and in various physico-chemical conditions: varied drug concentrations (5, 10 and 15 mg/L), temperatures (from 15.4 to 29.6 °C), and pH (from 3.2 to 8.8). Results The results showed that among alive biomass, T. versicolor (CB8) had the greatest sorption ability for bleomycin and P. nidulans (CB14) worked best for vincristine. The tested sorption process could be described by a pseudo-second order kinetics model. Sorption equilibrium studies demonstrated that for bleomycin Redlich-Peterson, while for vincristine Langmuir model fitted best. The thermodynamic studies showed that the sorption process was endothermic chemisorption for bleomycin, and exothermic physisorption for vincristine. For both drugs the sorption ability increased with an increase of the pH value. Conclusion The biosorption on fungal biomass is a favorable alternative to conventional wastewater treatment processes for anticancer drug removal.

“…The antidepressant, fluoxetine, was found to be adsorbed on zeolite, olive stone, sunflower, and walnut shell with sorption capacity in the range of 10 to 44 mg g −1 [162]. The same sorbents were also reported to separate nicotinic acid and pharmaceutical compounds, with higher sorption capacity in the range of 57 to 92 mg g −1 .…”

Water is a very valuable natural resource. As the demand for water increases the presence of emerging contaminants in wastewater has become a growing concern. This is particularly true when one considers direct reuse of wastewater. Obtaining sufficient removal of emerging contaminants will require determining the level of removal for the various unit operations in the wastewater treatment process. Membrane bioreactors are attractive as they combine an activated sludge process with a membrane separation step. They are frequently used in a wastewater treatment process and can operate at higher solid loadings than conventional activated sludge processes. Determining the level of removal of emerging contaminants in the membrane bioreactor step is, therefore, of great interest. Removal of emerging contaminants could be by adsorption onto the biomass or membrane surface, biotransformation, size exclusion by the membrane, or volatilization. Given the fact that most emerging contaminants are low molecule weight non-volatile compounds, the latter two methods of removal are usually unimportant. However, biotransformation and adsorption onto the biomass are important mechanisms of removal. It will be important to determine if the microorganisms present at given treatment facility are able to remove ECs present in the wastewater.
