Summary: Mining activities have economic benefits, but also environmental impacts on tailings generation and management. Biogeochemical processes, particularly microbial induced calcite precipitation (MICP), can modify the properties of tailings. MICP has potential for sustainable management of tailing deposits, with applications including removal or immobilization of heavy metals, creation of impermeable barriers, prevention of soil liquefaction, and control of windblown dust emissions. However, challenges remain in considering tailings' chemical composition, reducing urea requirements, determining optimal reagents dosage, evaluating long-term stability, and calculating associated costs.

Summary: Wind erosion is a significant natural calamity worldwide. This study evaluates the feasibility of using microbially induced calcium carbonate precipitation to mitigate wind-induced erosion in the Thar desert of India. The results show that the biocemented sand samples are more resistant to erosion compared to untreated sand, and longer treatment duration leads to thicker crust and higher surface strength.

Summary: The study investigated the application methods of Microbially Induced Calcite Precipitation (MICP) on different soil types for wind erosion prevention. It was found that the pouring method was suitable for medium sand, while the mixing method was more effective for other soil types. The presence of calcium reduced bacterial penetrability, impacting the effectiveness of MICP. Choosing the appropriate application method based on soil properties can help mitigate soil erosion.

Summary: The MICP technique utilizes ureolytic bacteria to decompose urea and generate carbonate ions for metal combination. It can remediate heavy metal-contaminated soils while maintaining or improving soil functions, but its efficiency in agricultural soil practical application still needs enhancement.

Summary: The study determined suitable chemical conditions to induce microbial-induced calcite precipitation (MICP) activity and explored its effectiveness in improving the mechanical properties of three types of natural fine-grained soils. The optimal chemical mixture helped increase the stiffness and shear strength of clay samples, but the improvements varied depending on the natural characteristics of the clay types.

Summary: The study found that compared to Sporosarcina pasteurii, the Staphylococcus equorum strain showed lower activity in microbial-induced calcite precipitation and copper removal. However, the halophilic feature of S. equorum was not considered, making it a promising bacterial strain for application in process water when seawater is used. Copper removal was insufficient, likely due to the formation of a copper-ammonia complex. Further research on the optimization of culture conditions for S. equorum in copper removal is needed for better performance in calcium, copper, or other metals precipitation.

Summary: Through fiber reinforcement and multiple MICP treatment, the performance of bio-bricks has been significantly improved, with increased flexural strength and strain. The optimal coconut coir fiber content is around 0.6%-0.9%. The multiple MICP treatment method can greatly enhance the resistance of bio-bricks against accelerated erosion.

Summary: Muskeg soil, which covers a significant portion of Canada, has high compressibility and low shear strength. This study investigates the application of microbially induced calcite precipitation (MICP) for enhancing the properties of muskeg soil. The results demonstrate that a bioslurry concentration of 0.4 mol/L exhibits the best compressibility properties.

Summary: This study explored the potential of MICP in reducing wind erosion of desert soil. The optimal cementation solution concentration and spraying volume were found to be 0.2 M and 4 L/m2, respectively. The results demonstrated that MICP significantly enhanced the soil bearing capacity and wind erosion resistance, with the sandy land showing maximum soil bearing capacity within three days and minimal wind erosion after 30 days.

Summary: Tailings are a significant type of hazardous waste, and their treatment is challenging and expensive. This study proposes a low-cost technique that combines microbially induced carbonate precipitation (MICP) and inorganic additives. Results show that CaO is the most effective additive, with an optimum dosage of 5%. The MICP-CaO coupled technique demonstrates high effectiveness in stabilizing heavy metals in tailings, with passivation rates 2%-866% higher than single techniques.

Summary: Climate change and desertification have led to increases in sandstorms and sand movements, causing health and economic losses. This study assessed the effect of microbially induced calcium carbonate precipitation (MICP) on the fixation of in situ dunes in northeast Iran, and found that the selection of soil stabilizers is crucial for dune fixation. Additionally, treating with MICP in conjunction with native plants positively affects the wind threshold detachment velocity.

Summary: In recent years, there has been a growing concern about the impact of anthropogenic noise from pile driving on underwater wildlife. Current guidelines for mitigating hydroacoustic effects rely on a simple transmission loss model, but it may not provide accurate results. A study using computational fluid dynamics found that geotechnical conditions may play a significant role in determining the sound loss during pile driving.

Summary: A new method for soil stabilization involving the combination of anionic surfactant and alkaline earth metals has been discovered. This method, known as surfactant-induced soil strengthening (SISS), improves soil strength by creating a matrix that binds soil particles together. The study focused on hand-mixing various combinations of sodium dodecyl sulfate and calcium chloride to strengthen beach sand. Results showed significant strength improvements, with an approximate optimization point determined based on pore volume. Additionally, surface percolation treatment was tested, but found to be less effective than hand mixing. Calcium mobilization was found to be more important than stoichiometric balance in terms of improving strength and reducing erosion.
