NBC soil, also known as neutralization, bioremediation, and carbonation soil, is a type of soil treatment method used in environmental engineering to neutralize and remediate contaminated soils.
NBC soil employs a process that utilizes the principles of bioremediation, where naturally occurring bacteria present in the soil are stimulated to break down and degrade harmful contaminants found in the soil. The bacteria feed on the organic matter present in the soil, effectively digesting and transforming the hazardous substances into non-toxic compounds.
In addition to bioremediation, NBC soil also utilizes carbonation, a process that introduces carbon dioxide (CO2) into the soil. The carbon dioxide reacts with water and alters the soil's pH, making it more alkaline and helping to deactivate the contaminants. This chemical reaction promotes the precipitation and immobilization of heavy metals and other toxins, reducing their mobility and making them less harmful.
The NBC soil treatment method is commonly used to address soil contamination issues caused by various pollutants, such as petroleum hydrocarbons, heavy metals, pesticides, and industrial chemicals. This approach is particularly effective in treating soils contaminated with organic pollutants due to its ability to stimulate the growth of specialized bacteria that can degrade these substances.
Overall, NBC soil serves as an innovative and sustainable method for remediating contaminated soils, as it harnesses the power of natural processes to restore soil quality and protect the environment from hazardous substances.
