Phytoremediation

Phytoremediation is fixing environmental problems through the use of plants. The name comes from the Greek φυτο, phyto meaning "plant" and Latin remedium meaning to "restore balance".

A type of this is phytomining, which is a method of extraction. Some plants absorb copper compounds through their roots. They concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds.
