Special Issue Information

Dear Colleagues,

The present Special Issue deals with wastes, their reduction, and their potential use as substrates to transform chemical energy into electrical energy. The main purpose is to promote measurements to implement a more sustainable circular economy and reduce the carbon footprint. Moreover, the 2030 Agenda for Sustainable Development aims to protect the environment and, particularly, goals 6 (Ensure availability and sustainable management of water and sanitation for all) and 7 (Ensure access to affordable, reliable, sustainable, and modern energy for all) aim at the need to accelerate sustainable electricity production technologies. There is an increasing concern about the role of both producers and customers in the role of generation and disposal of wastes, going from a delegated responsibility to a shared responsibility, which affects the commitment of the producers and generates a chain of responsibility that tries to minimize the waste produced by converting it into valuable products.

In particular, the topics of interest in this Special Issue include (but are not limited to):

  • Recent advances in the treatment of wastes and energy production;
  • Microbial fuel cells for sustainable energy production;
  • Waste-to-bioenergy processes;
  • Additive manufacturing for wastewater and bioelectricity generation.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly 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 2600 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.

This study aimed to estimate the bioelectricity production process using a vinasse solution through the application of Plackett–Burman and Box–Behnken designs. An electrochemical cell was constructed using Arduino to measure the potential difference between an anode and cathode immersed in a vinasse solution, which is a byproduct of wine production containing organic compounds and ions that undergo redox reactions. The Plackett–Burman design identified the most influential variables among eight previously selected (concentration of the electrolyte, pH, temperature, stirring, addition of NaCl, yeast dose and electrode:solution ratio). The results showed that the most influencing variables were the vinasse concentration and stirring and a peak of 306 mV could be observed for a 100 mL experiment. The third most influential variable regarding the process was NaCl addition, which showed its high influence at larger times. Based on these results, the Box–Behnken design was used to determine the possible ranges of variation of the independent variables (vinasse concentration, stirring and NaCl dose) to maximize the bioelectricity production. Therefore, with the combination of the intermediate concentrated vinasse (1:3 v/v ratio) and stirring, a peak of 431.1 mV could be observed when adding 2% NaCl after 15 min of the experiment. In what concerns the instant bioelectricity, measured after 1 min of the experiment, values up to 437.9 mV could be observed although yeast and/or NaCl are necessary at short times. This study provides insights into the bioelectricity production process from vinasse, contributing to the understanding and potential for sustainable energy generation. Full article
