Special Issue "Production and Utilization of Biogas"
Deadline for manuscript submissions: 31 July 2019
Biogas, although it is a mature renewable energy technology, still requires financial incentivization of commercial plants or end uses. Shortages of locally-available, very cheap digestible feedstocks restrain biogas productivity, so that biogas plants with a capacity greater than 1 MW are difficult to construct and operate in truly competitive markets. Research into innovations that could improve economic viability and resource flexibility of biogas technology is therefore needed. Potential improvements must be sought in the whole value chain of biogas: Cheaper feedstock production and collection including wastes, enhanced fermentation techniques, novel products that can be derived from feedstock processing or biogas, new end uses, integration with other technologies, market organization, etc. This Special Issue aims at encouraging researchers to address challenges associated with biogas production and utilization. It seeks research reports and innovative solutions that could contribute to the further development of biogas technology. In addition, the submission of review papers that systematically evaluate advances in biogass production and utilizaton with an emphasis on technological excellence and realistic commercial potential are also invited.Dr. Wojciech Budzianowski

Title: Production Techniques And Energetic Performance of Biogas In Rural Environment. A Review
Authors: Alvaro Ramirez Gomez; email: [email protected]
Abstract: The use of biogas produces a global benefit by reducing emissions of greenhouse gases such as CO2 and CH4. In rural areas, it is a substitute for conventional solid or liquid fuels such as kerosene or firewood, which contributes to the improvement of people's quality of life, and reduces the negative impact of the use of chemical fertilizers due to the accumulation of heavy metals in soil and groundwater.
The biogas has a calorific value between 16-20 MJ/m3 depending on the organic waste from which it is produced and the content of nutrients (proteins, fats, carbohydrates) in the substrates. It represents a low cost energy alternative, being used as fuel in kitchens, for heat generation and lighting in rural industries and production of electric power for small engines. Thus, for example, in countries such as China, India and Nepal, biogas is commonly used.
This work will present an exhaustive review of the factors that affect the performance of the process of generation and consumption of biogas in the rural environment. Aspects such as production rate and biogas quality per unit of potentially digestible material are addressed, depending on their composition, type of digester, pretreatments and operating conditions, as well as the performance obtained in its various applications for heating water, heating, steam generation and electricity production. We analyze the means used and available for the generation of biogas in rural areas, such as bags, buried drums and reactors, as well as operating variables such as temperature (optimum around 35 ºC), and maintenance of the acid-base balance during the digestion process (pH 6.6-7.6). In addition, the parameters of operation and energetic performance of rural consumption devices and domestic appliances (stoves and kitchens) are reviewed, conditioned by factors such as methane content (50-70%), relative density (0.7-0.9) of the biogas generated, as well as its supply pressure (around 10 bar).
