Phytoremediation is a technique that uses plants to remedy areas contaminated with heavy metals. This technique has great advantage due to the high diversity of vegetables that can be found in nature. This work aimed to make a technological survey of the phytoremediation methods used in the recovery of environments impacted by heavy metals. The research was carried out in the patent databases of the European Patent Office (Espacenet®) and the National Institute of Industrial Property (INPI), using the keywords: remediation, plant, soil, heavy metal, recovery and phytoremediation, and codes the B09C1/00 and A01H5/00 of the International Patent Classification. China was the highlight in this research, presenting the main inventors and universities holding patents, having the peak of deposit in the year 2009. The phytoremediation technique that is being more used is phytoextraction. Phytoremediative technologies are proving to be very promising for a market that is increasingly demanding and concerned about environmental impacts.
