Lead is present everywhere in the environment and has been defined as one of the greatest threats to the human health. In this paper, attempts have been made to study a way of recycling the lead produced from waste usage and disposed of in such a way as to avoid degrading the surrounding environment. In order to contain the waste, recycled asphalt material is mixed with the lead and then heated with microwave energy. This is an attempt to solidify and reduce the lead contaminants and use the final product as sub-base material in road pavement construction. The microwave heating of the specimens is carried out with 30%, 50%, 80% and 100% of power at 800W. The optimum power mode is used to compare with the conventional heating of asphalt with sulfur additive. The results are characterized by compact density, permeability, and subjected to toxicity test with regards to lead concentration. A mechanical test to evaluate the stability is also performed on the three methods of solidification and to prove that microwave zapping method allow to convert into an environmentally stable material for recycling without having to be deposited in a landfill site.

Party 25 involved the conception and public launch of a radically new form of political party during that year’s Australian general election. The entire project was also intentioned as a conceptual artwork. Party 25 avoided conventional party-political approaches and was neither a protest group nor an advocacy organisation, but rather a new form of political association that confronted what we understood as the debilitating limits and impotence of contemporary parliamentary democracies in transitioning our societies towards ecological sustainability.----- Party 25 was based on responding to one fundamental question which all of its policies served - “how does humanity get to the 25th century?” By basing itself on a dramatically long-term approach uncommon within conventional politics it raised the proposition that humanity does not have an assured future. Party25 therefore shaped its agendas around the idea that any future now lies in human hands and so how humanity treats the ecologies on which it depends innately determines the quality of the inseparable relationship between its being, and the being of the biophysical world.----- The project was conceived through a number of discussion papers, workshops and creative works and was launched publicly at the Judith Wright Centre Brisbane accompanied by a full length showing of evocative imagery, text and sound, a series of speeches and the launch of a succinct web presence. Through the website and this party launch a community of interested participants and creative practitioners was sought who then would form the basis of a nascent community of change.

Fundamental Sounds was a live, intercultural and multidisciplinary concert that presented a new synthesis of music, performance & visual arts addressing the imperative of sustainability in a new and evocative form. The outcome was a ninety-minute concert, performed at a major concert hall venue, involving four live musicians, numerous performers & large-scale projections. The images and the concert were scripted in three key phases that spoke to three epochs of human evolution identified by ontological designer and futurist Tony Fry - ‘Pre-Settlement’, ‘Settlement’ and the era that he suggests that we have now entered – ‘Unsettlement’ (in mind body and spirit). The entire work was professionally recorded for presentation on DVD and audio CD.----- Fundamental Sounds achieved a new synthesis between quality performance forms and cogent critical ideas, engendering an increasingly reflective position for audiences around today’s “era of unsettlement” – an epoch Fry has recognized that we must now move to quickly displace through adopting fundamentally sustainable modes of being and becoming.----- The concert was well attended and evoked a range of strong, reflective reactions from its audiences who were also invited to join and participate within a subsequent ‘community of change’ initiated at that time.
