Sustaining the shrinking footprint

Industry has increased its efficiency from what it was in the past, to the point where its current ecological footprint is a fraction of what it used to be.

Now imagine an industry sector that produces zero waste, is carbon neutral and husbands the earth’s resource endowment for future generations.

Algae that make biofuels and hydrogen

IMB_Ben_with_algaeAn Australian researcher is leading an international team of scientists developing a clean source of energy from microalgae. The team have developed one algae that not only makes oil for biodiesel production but also generates hydrogen. Commercial hydrogen production uses fossil fuels and produces carbon dioxide.

Australia’s place in the nanotechnology race

CSIRO_CliveD_GloveboxCSIRO researchers are applying nanotechnology to drug delivery, medical body imaging, nerve repair, smart textiles and clothing, medical devices, plastic solar cells (see From plastic money to plastic electricity) and much more.

“Nanotechnology is not an industry—it is an enabling technology,” says Clive Davenport, leader of CSIRO’s Future Manufacturing Flagship.

Eucalypts: the fuel of the future

Robert Henry is leading a project to use eucalypts and other non-food crops as a source of biofuel.

Up to 30 per cent of the fuel needed for Australia’s road transport and the aviation industry could be generated through biofuels, creating tens of thousands of jobs and adding $5 billion to Australia’s economy.

And one of the prime sources of biofuel, according to Southern Cross University’s Centre for Plant Conservation Genetics, could be eucalypts.
