Bioremediation is a waste management technique
that involves the use of organisms to remove or
neutralize pollutants from a contaminated site. Bioremediation is a “treatment
That uses naturally occurring organisms to break
down hazardous substances into less toxic or non
toxic substances”. Technologies can be generally
classified as in situ or ex situ. In situ bioremediation
involves treating the contaminated material at the
site, while ex situ involves the removal of the
contaminated material to be treated elsewhere. Some
examples of bioremediation related technologies are
phytoremediation, bioventing, bioleaching ,
landfarming , bioreactor , composting,
bioaugmentation , rhizofiltration , and biostimulation .
