WYNDHAM’S WASTE WEAPON Our sculpture aims to progressively build a new topography on the existing site. We approach this in two ways: firstly, through community initiative, involvement and awareness; and secondly, distribution through technological advancement via a robotic system. It is a concept that demonstrates a deep understanding of the present day crisis of a downward spiral environment. We approach this project with a rational attitude: developing a design upon a self-evolving and transformed platform which is ecologically sound, environmentally self-sustaining, and financially cost effective and profitable. Let us use the benefits of technology- the artificial, to sustain and ensure the longevity of our planet- the organic. It is this symbiotic relationship that harnesses human ingenuity to transform harmful by-products to useful and beneficial outcomes: returning waste back to earth, mother nature. Philosophical underpinnings: designer/ architect losing control of, not determining the final outcome, once project enters implementation stage.
SHORT TERM GOAL
LONG TERM GOAL
To create a green waste facility: while Wyndham City Council continues working on one, we’re providing a temporary solution to this
Eventually project will reach maximum height; after that stage, new stage of plantation anticipated

VERY CURRENT ISSUE Green Waste Actions 2002 Strategy: Promote current user pays fortnightly 240L MGB green waste collection service. Investigate options regarding extending the service to all Wyndham residents. Promote use of Regional waste facility and ensure waste material is composted

^ Of rate payers money is spent annually on the current organic bin service
+Greater sensitivity and willingness to participate in sustainable principles
GENERATION
With 2411 tonnes per year of green waste being generated municipality-wide, our landscape would be completed in 4.84 years. 4.84 years x $216,990 spent per year on surrendering green waste to tip = $1,050,231.60 savings in total.
TECHNOLOGY
Google car would cost approximately $100,000 based (estimated figure). The mulching machine price varies from $39,000 to $275,000 depending on size and loading capabilties for one which could get the job done just fine in a larger amount of time
^ Used this service as at April 2010
^ Tones per year of garden waste collected
+In of Wyndham’s population in 2012 is made up of families
Assuming that a cubic metre of green waste will weigh around 150kg (the estimated figure for skip bin weight limitations), then 77,750 cubic metres x 150 kg = 11,662,000 divided by 1000 to get the amount of tonnes = 11,662 tonnes of green waste can fit on our site)
^ The garden waste collection service is currently optional. Residents pay a fee of above value for a fortnightly 240L green bin service
16,630 +In 2011, the most populous of any 5 year age group was zero to four years, with over sixteen thousands persons making up this age group. This is estimated to be approximately ten percent of the Wyndham’s population.
