Special Issue Information

Dear Colleagues, 

Biomass without appropriate treatment can cause substantial environmental problems, but proper treatment and disposal of organic biomass can be expensive. In this Special Issue, we focus on waste-to-energy (WTE) technology that can treat organic biomass and produce renewable energy in the form of gas, electricity, and/or heat through combustion, pyrolyzation, anaerobic digestion, landfill gas recovery, or gasification. WTE technology provides potential alternative fuel sources to fossil fuels and helps to reduce landfill disposal cost around the globe. There is a demand for new or innovative techniques to improve the efficacy of existing WTE technology and reduce the disposal cost, providing sustainable waste treatment options for a better future. 

This Special Issue aims to gather research papers on recent developments and innovation for WTE technology. We invite researchers to submit research and review articles that describe new insights on renewable energy production from biomass and its utilization processes to push forward the development of new efficient WTE technologies. The research can range from lab-scale to full-scale case studies. 

This topic will include a series of research and review articles covering, but not limited to, the following subjects:

  • Bioenergy production from biomass through anaerobic digestion, dark fermentation, photo fermentation, microbial fuel cell, and microbial electrolysis cell;
  • Biomass conversion to bioplastic and improvement in VFA production;
  • The use of innovative methods to improve energy production from alternative wastes;
  • Development of pretreatment processes to increase energy production from feedstocks;
  • Maximizing the energy production of solids wastes from pyrolysis, gasification, and combustion;
  • Improved wastewater treatment processes through integration with energy production.

Manuscripts can be submitted until the deadline. All papers will be 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. Sustainability 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 1900 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.

The world population maintains a growing trend and in turn, the amount of municipal waste is also increasing. Rising municipal waste quantity poses a challenge for human beings and the environment, therefore recycling becomes important for environmental sustainability and circular economy. This study explores the effects of municipal waste recycling and renewable energy on the environment sustainability proxied by CO2 emissions in EU member states over the period from 2004 to 2017 through panel cointegration and causality analyses. Recycling is considered an efficient way to reduce CO2 emission, but surprisingly our results indicate mixed findings. The causality analysis revealed no significant interaction among recycling rate, renewable energy and CO2 emissions. However, in the long run, the negative impact of recycling and renewable energy use on CO2 emissions were revealed but varied among the countries. Results indicate that increasing renewable energy consumption will play a significant role in reducing greenhouse gas emissions. These findings must raise awareness among policymakers that should focus on the adoption and implementation of different types of sustainable energy policies that can affect directly or indirectly renewable energy sector development.
