Species Selection Greenhouse study
(Landfill leachate, Brisbane) 2000-2001
PhytoLink Australia managed this project for Brisbane City Council, which tested the growth and transpiration performance of a range of tree, shrub and grass types using leachate from the Roghan Road Landfill as the irrigation medium for the study. 70 species were tested over a ten month period to ascertain which of these could be used effectively as biopumps for
leachate control. 15 species have been considered successful both in terms of leachate tolerance and evapotranspiration ability and will be further studied in a Field Trial at the Nudgee Landfill commencing in September 2001.The research for this study was carried out by Dr. N. Ashwath and was advised by Dr. Ari Ferro, President of Phytokinetics Inc., a leading US company in the field of
phytoremediation. In overseas projects hybrid poplars and willows have been successful in soil remediation and in pumping, metabolising and transpiring contaminated
water. A central objective of this project (and PhytoLink Australia’s wider program) is to demonstrate the effectiveness of selected Australian natives against this international
standard. Phytoremediation strategy PhytoLink Australia contracted Phytokinetics Inc. to review Brisbane City Council’s wider landfill leachate problems and to prepare a strategy for implementing phytoremediation solutions. This strategy report was presented to Brisbane City Council in June 2001.
