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
WHY COMPOST?
VERY CURRENT ISSUE
To create a green waste facility: while Wyndham City Council continues working on one, we’re providing a temporary solution to this
• Currently an unused resource • Waste management strategy • Immeasurable environmental benefits
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
IMPROVES
LONG TERM GOAL Eventually project will reach maximum height; after that stage, new stage of plantation anticipated
REDUCES INCREASES
Other non recyclable 27%
Food organics 43%
PROTECTS
• • • •
Soil structure Nutrient holding capacity Root growth Water infiltration and drought tolerance
• Fertiliser requirements • Micro/Macro organism production
PROGRESS
10 ,124 Collections as at April 2010. Mandatory green waste collection service is supported by Council. Waiting for availability of facility in 2 years time *
• Plants from disease

PERSPECTIVE VIEWS
+Birth rate increase over the past twenty years in Wyndham
+Increase over ten years, with a 6.7% growth rate per year.
42.9% +In of Wyndham’s population in 2012 is made up of families
CURRENT STRATEGIES
+Over the next ten years, it is forecased that there will be this number of children born to Wyndham mothers.
+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.
WHAT DOES THIS MEAN? +Greater sensitivity and willingness to participate in sustainable principles
^ Cubic meters of bundled branch collection occurs twice annually
^ Of rate payers money is spent annually on the current organic bin service
^ The garden waste collection service is currently optional. Residents pay a fee of above value for a fortnightly 240L green bin service
^ Tones per year of garden waste collected
^ Used this service as at April 2010
^ Of waste currently sent to landfill comprises of food and garden organics

DESIGN PROPOSAL SPECIFICATIONS 25, 916.63 square meters X 3 meters height = 77,750 cubic meters
HOW MUCH OUR PROPOSAL WILL SAVE YOU
$413,000 $700,000
SCALE
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)
Savings per year
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
Savings from tip fees
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
