Special Issue Information

Dear Colleagues,

Given the challenging decarbonization goals established by Europe for 2050, there is an urgent need to replace fossil fuels-based energy with renewable energy technologies. Industries are responsible for around 1/3 of the total global greenhouse gas (GHG) emissions, of which 90% is contributed by the top 10 industries. For example, in 2014, Energy Intensive Industries (EIIs) were responsible for over one-third of the EU's greenhouse gas emissions, totaling more than 508 million metric tons of CO2 equivalent.

The aim of this Special Issue is to compile relevant research that address the substitution of fossil fuel-based energy with waste-derived energy, particularly focusing on the sustainability of the transition processes. We invite submissions of original research articles and reviews, in areas that may include (but are not limited to) the following:

  • Biomethane as a renewable source of energy in EIIs;
  • Renewable syngas production optimization to substitute fossil fuel-based energy;
  • Biomass as a renewable and sustainable substitute of fuels in EIIs;
  • New value chains from waste to produce different energy carriers;
  • Life cycle assessment in waste value chains;
  • Green hydrogen from waste as a source of energy for EIIs.

We look forward to receiving your contributions.

Best regards,

Dr. Carmen Bartolomé

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. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

The importance of small- and medium-sized enterprises (SMEs) from economic, social, and environmental point of views and the crucial role of energy efficiency are widely recognized. However, the development of effective policies and their analysis are still challenging topics, for which research is relatively scarce. The main reasons for this are the high heterogeneity of SMEs, their low energy impact compared with energy-intensive enterprises, the lack of quantitative in-formation on the energy consumption of SMEs, and the low awareness of SMEs on energy topics. The structural paradigm change in the energy markets has underlined the importance of EE in SMEs. Several studies have been devoted to analyzing EE policies, using different methods and targets, not necessarily with a focus on SMEs or quantitative figures. This study presents a scoping review aimed at mapping the scientific literature on this topic, assessing its volume, nature, characteristics, type of evidence available, key concepts, and possible gaps. The existing contributions were systematized on three assessment levels regarding the EE policies for SMEs: general framework for their classification; comprehensive analysis of contributions providing qualitative information; in-depth analysis of evaluation studies including quantitative information. This study highlights the need for a good balance between economic and supportive mechanisms and the crucial role of energy audits. The analyzed contributions show that despite SMEs’ efforts to develop EE policies, there are still important barriers to be addressed. Moreover, there is an important lack of quantitative analyses, which are necessary for the development a harmonized policy evaluation approach. Based on a synthesis of the review findings, key learnings for the better design, implementation, and evaluation of EE policies for SMEs are provided. Full article
