Special Session 1 

 Microbial Biomineralization : 
 From Fundamentals to Sustainable Construction and Geo Environmental Applications 

Session host: Cao Bin



Microbial biomineralization is the bio-chemical process by which solid minerals such as calcium carbonate are precipitated from the environment. Compared with conventional chemical processes for the formation of solid minerals, microbial biomineralization is more environmentally friendly and provides a promising technical route to low-carbon construction. In addition, microbial biomineralization also provides a solution to containing toxic environmental contaminants such as heavy metals and preventing their further spread to the surrounding environment. In this session, we invite submissions that tackle emerging challenges in all aspects of fundamentals and/or applications of microbial biomineralization. The relevant topics include, but not limited to,


  • Engineering biomineralization processes through synthetic biology and bioengineering approaches

  • Novel microbial or enzymatic processes for biomineralization

  • Applications in construction and geotechnical engineering

  • Applications in environmental remediation and resource recovery

  • Techno-economic analysis (TEA) and life cycle assessment (LCA) of microbial biomineralization in various applications

Special Session 2 

 Utilization of solid wastes and environmental applications 

Session host: Yi Yaolin and Fei Xunchang



A wide range of solid wastes has been generated due to the rapid growth of population and economy. Examples of solid wastes are construction and demolition wastes, municipal solid wastes, incineration bottom ash, incineration fly ash, mining and tailing waste, dredged river/marine sediment, steel slag, etc. Reusing solid wastes reduces the strain on natural resources, minimizes landfill waste, and conserves energy, contributing to a more sustainable and eco-friendlier environment. Given the wide variety of solid wastes, their environmental applications, impacts, health risks, and regulatory measures are yet to be fully understood and developed.


This sub-session aims to provide a forum for researchers to present and discuss the utilization of solid wastes and environmental applications, including 1) recycling and upcycling innovations, 2) circular economy strategies, 3) sustainable construction materials, 4) environmental impact and risk assessments and other related topics. The insights, pioneering research, and discussions on real-world applications by researchers will promise to enhance waste management practices, conserve resources, and promote a healthier environment.
