Phytoremediation is not new the use of plant material as well for anerobic digestion is new and requires as you are aware cutting more frequently at 3-5 feet so we have some primary use either in bioenergy or wind use. All interesting here is the Selectra 6/6pr!

Giant King Grass can be used as a windbreak to prevent dust from spreading and to prevent soil erosion. The subsurface root system will add organic matter and help create soil from the crushed rock. The Giant King Grass may take up heavy metal contaminants from the slimes dams and contribute to remediation. Food crops are not possible because of the contamination in the soil. Selectra's goal is to use the Giant King Grass as a feedstock for either anaerobic digestion or direct combustion to produce electricity and therefore create value from these slimes dams for themselves and their partner gold mining company. It may be possible to remove
the heavy metal contaminants from the anaerobic digestate as well.

Selectra Commercial Director Dwight Rosslee reports, "Giant King Grass is growing well on the slimes footprint and we are pleased with the results so far. We are entering a critical phase of the tests as we need to model plant growth during our winter months and the early signs are most encouraging as the plants have continued to grow under the frost covers. In this regard we have extended the trial to December 2013 and thereby having almost 12 months data." Rosslee attributes the success of the trials to Giant King Grass' unique properties coupled with Selectra's proprietary soil treatments - "the slimes footprint where the tests are taking place are very unhospitable towards crop establishment with just about no organic loading, no nutrients and is acidic with an average pH of 4."
