How can a long term phytoremediation project be realised despite changing future political interests at White Bay?
...more than an ecological solution to realise a long-term phytoremediation project?

In Australia, “There are somewhere between 40,000 and 80,000 contaminated sites. We spend about $300-million a year managing and remediating them. The overwhelming majority of that goes on the managing, using dig and dump to take the pollutants

Different phytoremediation and bioremediation techniques have been applied to the polluted plots where crops are grown for material and energy production whilst also cleaning the soil. In some cases, the level and type of pollution has permitted temporary activities to take place on the plots while bioremediation continued, opening up flexible development options

“Landscape Architecture should no longer be about the Landscape architect as a master architect, where we do funky design and we say this is how it should be...
it should be more of a gardening approach; intervening, letting things take their time, stepping back, testing, failure and error, working with the land...”
