Microbial induced carbonate precipitation (MICP) as biotechnology is extensively regarded to benefit the sustainable development of civil engineering, mining engineering. MICP can improve the engineering characteristics of soil, rock, and concrete (including strength, rigidity, seepage, durability, thermal conductivity, and expansibility). MICP can be applied for the surface protection and crack reparation of buildings and structures, the enhancement of civil engineering materials, permeability reduction of the dam, and underground engineering by bio-grouting, the improvement of foundations with liquefiable soil or expansive soil, and polluted soil restoration.

However, there is still an uneven distribution of carbonate induced MICP in soil and rock, lack of catalytic controlling methods for MICP processes, and occasional large engineering applications of MICP. A general agreement regarding how to address the engineering challenges has not yet been reached. Biotechniques are promising tools for civil engineering, traffic engineering, and mining engineering. Research focussing on MICP and other biotechnologies are urgently needed to find solutions.

The aim of this Special Issue is to collate original research articles investigating new MICP technologies, especially those related to novel biotechniques, and outstanding applications (e.g., in civil engineering, traffic engineering, etc.). Review articles discussing the state of the art are also welcome.

Potential topics include but are not limited to the following:

• Numerical simulation of MICP mechanism
• Applications of MICP in engineering
• Novel biotechniques in civil and mining engineering
• MICP improvements in special soils such as calcareous soil, expansive soil, and soft soil
• MICP applications in environmental geotechnical engineering
• MICP applications in rock engineering
• MICP applications in mining engineering such as petroleum and gas exploitation, and mine restoration
• Microbial cement and its applications
• MICP application in crack reparation of buildings and structures
• Catalytic controlling methods in MICP processes
• Biotechnology products in civil and mining engineering
• Artificial intelligence-based techniques in solving problems related to MICP application engineering
• Swarm-based models for optimising MICP applications in civil and mining engineering
• MICP micro-scale to MICP macro-scale properties
• New characterisation methods for MICP process
