Bioremediation: An Alternative to Conventional Remedial Technologies
Advances in technology and industrialization, bring with them, their unpleasant partners, pollution and degradation of the environment. The effects on the environment connected with industrial activities are mainly related to the production of industrial wastes. Management of these wastes is evolving with time and complexity of the problem. The conventional techniques used for remediation have been to dig up contaminated soil and remove it to a landfill, or to cap and contain the contaminated areas of a site. The methods have some drawbacks. A better approach than these traditional methods is to completely destroy the pollutants if possible, or at least to transfer them to innocuous substances. Bioremediation, or the use of organisms for the removal of contamination or pollutants has become a popular option. Bioremediation is an option that offers the possibility to destroy or render harmless various contaminants using natural biological activity. As such, it uses relatively low-cost, low-technology techniques, which generally have a high public acceptance and can often be carried out on site.
