The need to safeguard our planet by reducing carbon dioxide emissions has led to a significant development of research in the field of alternative energy sources. Hydrogen has proved to be the most promising molecule, as a fuel, due to its low environmental impact. Even if various methods already exist for producing hydrogen, most of them are not sustainable. Thus, research focuses on the biological sector, studying microalgae, and other microorganisms’ ability to produce this precious molecule in a natural way. In this review, we provide a description of the biochemical and molecular processes for the production of biohydrogen and give a general overview of one of the most interesting technologies in which hydrogen finds application for electricity production: fuel cells.

“…In parallel, the highest detected concentration was for carbamazepine (4.4199 μg/L), followed by amoxicillin (1.53 μg/L), clarithromycin (0.00898 μg/L), omeprazole (0.00156 μg/L), metformin and erythromycin (below detection limit). Even though several studies have investigated the pharmaceuticals levels in wastewaters [1], it is known that such contaminants are actually dependent on several factors including the plant dimension, operational conditions and daily water flow, as well as the inhabitant serving and the local drugs consumption [30][31][32]; therefore, a comparison with the literature data is not possible [33]. However, the findings of this study are consistent with those of many reports in the literature, where low concentrations (in the range of μg/L) of pharmaceuticals have been found in municipal wastewater [12].…”

Pharmaceuticals constitute one of the most important emerging classes of environmental pollutants. A three‐phase solvent system of water, water containing 0.1% of formic acid and acetonitrile was successfully used to separate, by liquid chromatography with mass spectrometry (LC‐MS), polarity‐matched pharmaceuticals, that is, carbamazepine, clarithromycin, and erythromycin, as well as amoxicillin and metformin. Despite of polarity similarities, these pharmaceuticals were completely resolved in the analytical run time of 15 min. The optimized three‐phase solvent system based‐method was validated for the simultaneous analysis of six matched‐polarity pharmaceuticals in wastewater samples. Good linearity (coefficient of determination more than 0.993) and precision (relative standard deviation less than 15.66%) were achieved. Recovery of analytes from the wastewater was between 0.70 and 1.18. Limits of detections ranged from 0.0001 to 0.5114 µg/L. No significant matrix effect, evaluated by post extraction addition, was observed in the electrospray ionization (ESI) source. Then, this methodology has been successfully applied to environmental study of pharmaceutical residues occurring in influent and effluent wastewater samples, from the main wastewater treatment plant in Potenza (Basilicata, Southern Italy).

Due to the impact of methane, carbon dioxide and nitrous oxide on global warming, the quantity of these greenhouse gases (GHG) emissions from municipal wastewater treatment plants (WWTPs) has attracted more and more attention. Consequently, GHG emssions from the two popular treatment technologies: anaerobic/ anoxic/ oxic (AAO) process and sequencing batch reactor (SBR) should be properly identified and discussed toward the current situation in developing countries. Direct and indirect carbon dioxide (with and/or without including in Intergovernmental Panel on Climate Change (IPCC) report) are all discussed in this article. This literature study observed that a quantity of total carbon dioxide emissions from SBR (374 g/m 3 of wastewater) was double that of AAO whilst ten per cent of these was direct carbon dioxide. Methane emitted from an SBR was 0.50 g/m 3 wastewater while 0.18 g CH 4 /m 3 wastewater was released from an AAO. The level of nitrous oxide from AAO and SBR accounted for 0.97 g/m 3 wastewater and 4.20 g/m 3 wastewater, respectively.Although these results were collected from different WWTPs and where influent was in various states, GHGs emitted from both biological units and other treatment units in various processes are significant. The results also revealed that aerated zone is the major contributing factor in a wastewater treatment plant to the large amount of GHG emissions.
