Selected Papers from ICEER 2017: 2017 the 4th International Conference on Energy and Environment Research

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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. ChemEngineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
