Special Issue Information

Dear Colleagues,

The current state of development of nations is based on energy consumption, and developing countries naturally aspire to reach a state of development, which, by actual standards, demands huge amounts of energy. Not only is fossil-derived energy becoming scarce (in order to fulfil these needs), but also the related environmental impacts are the basis for climatic changes. This has pushed scientists and decision makers towards the development and implementation of renewable energy systems, as well as of more efficient energy systems.

Thus, attention has been directed to solve problems, such as the development of systems for the storage of surplus renewable energy, produced for later use, or its immediate use in the production of energy carriers, such as hydrogen or methane, or even the production of cleaner fuels for transportation in modern cities. On the other hand, the problems associated with environmental contamination due to waste and wastewater generation call for the valorization of wastes through the production of biofuels, valuables, and/or energy, through a biorefinery concept, and for the biological and chemical treatment of wastewater. The use of life cycle assessment tools allows one to better plan these systems.

The Paris Agreement, achieved in December 2015 by several countries, has set new and tighter targets for sustainable development, leaving each country the responsibility and the freedom to draw up their plans and to achieve them. Now is the time to explore emerging technologies and concepts in a collaborative way, bringing together engineers, researchers, and professionals from different areas.

This Special Issue, therefore, aims to contribute to the Sustainable Energy agenda through advanced scientific and multi-disciplinary knowledge, combined to improve renewable energy availability and control environmental pollution. We, therefore, invite papers on innovative technical developments, reviews, case studies, analytical, as well as assessments, from different disciplines, which are relevant to renewable and cleaner energy, and to environmental remediation and pollution control.

Reducing the levels of heavy metals in wastewaters below the permissible limits is imperative before they are discharged into the environment. At the same time, water treatment technologies should be not only efficient, but also affordable. In accordance with these principles, this study assessed the possibility of recovering iron-contaminated residues, resulting from the treatment of synthetic acid mine drainage, for the subsequent remediation of Cr(VI) polluted aqueous solutions. Bentonite, an inexpensive and available natural material, was used as an adsorbent for the removal of Fe(II) from synthetic acid mine drainage (AMD). Then, Fe(II)-contaminated bentonite, the residue generated during the treatment of AMD, was recovered and activated with sodium borohydride in order to convert the adsorbed Fe(II) to Fe(0). Subsequently, the Fe(0)-containing bentonite (Be-Fe(0)) was further used for the treatment of Cr(VI) contaminated aqueous solutions. Reactive materials investigated in this work were characterized by means of scanning electron microscopy-energy dispersive angle X-ray spectrometry (SEM-EDX), X-ray diffraction spectroscopy (XRD), point of zero charge, and image photographs. The effect of several important parameters (pH, temperature, metal concentration, and ionic strength) on both treatment processes was investigated and discussed. It was shown that the efficiency of Cr(VI) removal with Be-Fe(0) was much higher than with bentonite. On the basis of the present study it can be concluded that residues generated during the treatment of AMD with bentonite can be used as a cheap precursor for the production an Fe(0)-based reagent, with good Cr(VI) removal potential.
