is a term given to a group of plants whose main characteristics consist of their ability to 'accumulate', to draw heavy metal residues from the soil. Research into these plants opens up a number of new possibilities of cleansing polluted soil.


are improved versions of the 'hyperaccumulator' plants. Developed jointly with the US, France and Germany, they represent a major leap in their capacity to draw large quantities of heavy metals from the soil. The implications of this project should be understood in terms of time, implying a more realizable, human scale dimension to the overall duration of a soil-cleansing project.
Today the new breed of plants are all becoming highly guarded, privately owned 'brands', therefore gaining access to these plants for research is difficult and costly.
