Special Issue Information

Dear Colleagues,

The requirements of sustainable and appropriate waste management are becoming an international challenge and a priority for the global community. Although the waste management sector is advanced, efficient, innovative, and economically viable technologies are needed. The priority is to save energy and care for the protection of the natural environment. The solutions sought should be in line with the sustainable development, bioeconomy, circular economy, material and energy recycling, support renewable energy technologies and reduce greenhouse gas emissions to the atmosphere due to the combustion of fossil fuels. An important research field is therefore the bio-energy production.

Bioenergy is one of many diverse resources available to help meet our demand for energy. It is a form of renewable energy that is derived from recently living organic materials known as biomass, which can be used to produce transportation fuels, heat, electricity, and products. More specifically, the feedstocks for bioenergy production include the waste streams from food processing industries, forestry and agricultural sectors, pulp and paper mills and many others, which turns waste into valuable energy and helps the transition toward a circular and sustainable economy.

This Special Issue aims to present and disseminate the latest achievements related to theoretical assumptions, results of scientific and implementation research, design, modelling and optimization of technological systems, as well as control and monitoring of solutions related to sustainable Bio-Energy Production. Therefore, this Special Issue will focus on current biomass pretreatment methods and technologies for energy recovery, the current status and technologies for obtaining biofuels from biomass, including pyrolysis products; pellets, briquettes and tablets, biogas, biohydrogen, biodiesel, bioethanol, biochitan and syngas, biorefineries, the modeling and optimization of the technologies for energy recovery from biomass and also techno-economic analysis (TEA) and life cycle assessment (LCA) for converting biomass and organic waste into bioenergy.

We invite you to publish original scientific contributions and review papers summarizing the achievements to date in this research field and indicate the strengths and weaknesses of the available technologies. The critical analysis of this will allow us to indicate directions for further development.

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. Energies 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.

The disposal of municipal biowaste is associated with the formation of malodorous and frequently hazardous volatile compounds. The composition of volatile pollutants formed during composting of mechanically sorted organic fraction of municipal solid waste (ms-OFMSW), sewage sludge (SS), food waste (FW), and wood waste (WC) during 28 days in a laboratory setup was analysed using electrochemical measurements, gas chromatography, and solid phase microextraction. Despite the close biodegradation intensity of SS+WC, ms-OFMSW, and FW+WC, the average temperature values were 57.0, 51.7, and 50.6 °C. The emission of volatile substances per day were: CO2 0.64, 0.68, and 0.64 g/kg, NH3 22.3, 93.1, and 4.9 µg/kg, CH4 5.3, 1.5 and 8.7 mg/kg, H2S 5.0, 3.3 and 1.8 µg/kg organic matter. The ratios of emission from SS+FW, ms-OFMSW and FW+WC for inorganic substances were 1.0, 1.1, and 1.0, and for organic compounds (VOC) were 1, 24, and 123. A total of 121 VOC was identified. The 12 N-containing compounds detected at the beginning of composting, some of which are highly toxic, ranged from 3.2 to 21.0% of the total VOC and belonged to amines with a very low olfactory thresholds and heterocyclic compounds. The results of this research help to optimise the systems used to remove pollutants from exhaust air. Full article

Since the impending warning of fossil fuel inadequacy, researchers’ focus has shifted to alternative fuel generation. This resulted in the use of a wide variety of renewable biomass sources for making biofuels. Biofuels made from biomass are seen as the most promising long-term strategy for addressing issues associated with conventional energy sources, atypical climate change, and greenhouse gas emissions. Hydrocarbons may be efficiently extracted from biomass, which contains a lot of sugars. Biofuels including bioethanol, biodiesel, biohydrogen, and biogas can be produced from biomass for widespread usage in transportation, industry, and households. In recent years, there have been numerous reports of breakthroughs in the manufacturing of biofuels and biogas. This paper examines the big picture of biogas generation, with an emphasis on the many forms of biomass utilization in both commercial and residential settings in rural areas. Full article
