About this Research Topic
In the context of dual-carbon targets, conventional pollutant treatment and recycling technologies face major challenges, such as reducing energy consumption and greenhouse gas emissions. Recently, the first wastewater resource recovery factory (WRRF) in China, the Yixing Concept WRRF, was put into operation, promoting the new concept of "wastewater is a resource and a wastewater treatment plant is a resource factory". Other technologies for simultaneous waste treatment and energy recovery (e.g. bioelectricity, hydrogen and methane) and dealing with new pollutants, novel biotechnologies in soil/water have attracted widespread interest. However, in order to expand the applications of these novel concepts, related research should be conducted systematically, which is addressed in this proposed research topic. In general, technological breakthroughs and innovative concepts can help us achieve efficient waste/water treatment and recycling, and eventually contribute to net-zero emissions.
This Research Topic will focus on the bioprocess and bioengineering for waste treatment and recycling. The main research topics are listed as follows (but not limited to), and submissions of original research, short communication, review, and perspective are welcome.
• Novel technologies and the mechanisms for biological waste treatment and recycling.
• Bioelectrochemical systems for waste/water treatment and resource recovery, electroactive microbiology and its scaling-up applications.
• Sustainable wastewater treatment processes in the context of dual-carbon goals.
• Biodegradation of emerging pollutants, such as personal care products, pharmaceuticals, industrial compounds, etc.
• Bioplastic and biosolids (e.g., microplastics, starch, cellulose, and organic matter) management in the water environment, and waste treatment processes.
• Bioremediation and biotransform of soil pollutants, including organic compounds, heavy metals, and pesticides via in-situ or ex-situ methods.
• Other low-carbon bioprocesses and bioengineering technologies proposed for waste/water treatment and recycling.
