About this Research Topic
Carbon dioxide (CO2) emission from fossil fuels combustion is one of the largest contributors to greenhouse climate effect. Compared with fossil fuels, biomass is a clean and renewable energy source with huge reserves. It is estimated that the annual global biomass yield, including municipal sewage, food waste, agricultural waste, and livestock manure, is approximately 150 billion metric tons. Anaerobic digestion of biomass can not only be in favor of achieving CO2 emission reduction but also produce biogas as alternative energy to supplement fossil fuels shortage. Thus recycling biomass waste is an effective way to turn “waste” into “wealth” and achieve a circular economy and sustainable development.
With the massive production of biomass around the world, proper biomass treatment has become the focus of attention at present. Anaerobic digestion is considered to be one of the most promising strategies for the high-quality utilization of biomass. However, how to achieve efficient bioresource conversions, such as anaerobic digestion to produce methane or other value-added chemicals, is still a key limiting problem to promoting waste recycling. Meanwhile, the effects of emerging pollutants contained in the substrate on anaerobic digestion should also be concerned. In addition, the biogas upgrading and reuse of liquid products (e.g., short, medium, and long chain fatty acids) are of great significance for the development of anaerobic digestion industrialization. More efforts can be made to accelerate technology transformation, overcome technical barriers, improve application efficiency, etc., to realize the full recycling of waste in the true sense.
This Research Topic is devoted to the latest research on the utilization of biomass, including:
• anaerobic digestion for methane and value added chemicals (e.g., medium and long chain fatty acids) production
• impact of pollutants on anaerobic digestion
• biogas upgrading
• application of methane
On the one hand, it is necessary to strengthen the methane production capacity of anaerobic digestion, promote the purification of biogas, increase the methane content and expand the application of biogas. On the other hand, find effective methods to promote anaerobic digestion to produce medium and long chain fatty acids. In short, we are interested in all types of manuscripts related to the above research directions.
