bioremediation

Bioremediation is the use of microorganism metabolism to remove pollutants. Some examples of bioremediation technologies are phytoremediation, bioventing, bioleaching, landfarming, bioreactor, composting, bioaugmentation, rhizofiltration, and biostimulation.

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 bioremediation involves the removal of the contaminated material to be treated elsewhere.
