Abstract:
Remediation in the environment is a measure for remediation of existing pollution in order to reduce the concentration of pollutants to a level that does not pose a threat to the environment. Bioremediation is basically a process which represents the ability of microorganisms to decompose different dangerous contaminants, and it has an increasingly key role in detoxification of contaminated soil and groundwater. These processes are getting their place owing to capacity of enzyme metabolism of microorganisms to transform organic contaminants into pollutants and less dangerous compounds. But, we shouldn’t forget that this method cannot always be applied. Among the available options for purification of contaminated soils, bioremediation is the best because it is less disturbing to environment and from the economic point of view-it costs less. Soil contamination occurs as a result of excessive discharge of hazardous substances and their "mixing" with substances that are naturally present in the soil. Disposal of waste to inadequately equipped landfills poses a potential threat to pollution of environment. Waste dumps can impair the quality of surrounding land, surface and underground water. Thus, the basic research questions are: what is worth keeping and preserving in an abandoned and underused industrial complex in the context of urban regeneration, what is meant by its identity and unique character of the site and how to formulate models of transformation of abandoned industrial complexes with the goal of preservation and enhancement its identity and achieving positive regeneration effects?
