Sustainability Assessment of MICP for Ground Improvement

Microbially Induced Calcite Precipitation (MICP) is a promising ground improvement technique that has attracted meaningful consideration recently, because of its potential to enhance soil properties and reduce the environmental impact of conventional soil stabilization techniques. However, the sustainability of this technique needs to be evaluated in terms of economic, environmental, and social factors. Economically, the cost-effectiveness of MICP needs to be assessed, taking into consideration the initial investment, maintenance, and long-term benefits of the technique. Environmental sustainability needs to be evaluated by analyzing the carbon footprint and other environmental impacts of the process. Also, the feasibility of using locally available materials for the process needs to be assessed to reduce the environmental impact of transportation and associated carbon emissions. Social sustainability needs to be assessed in terms of the potential health risks associated with the use of microbial agents, as well as the impact of the process on local communities. A comprehensive sustainability assessment should also consider the ethical implications of using biotechnology for ground improvement purposes. Hence, the sustainability assessment of MICP for ground improvement requires a multi-disciplinary approach that considers, economic, environmental, and social factors. The results of such an assessment can help in developing sustainable and resilient solutions for ground improvement.
