Associate Professor Justin Chalker: My name is Justin Chalker.

I’m an Associate Professor at Flinders University and our research focuses on sustainable chemistry.

My research interests centre on converting waste materials into valuable polymers that protect the environment.

These materials are useful in a variety of applications.

They can capture heavy metal pollution such as mercury. They can clean up oil spills. These materials serve as components of slow release fertilisers.

And they can also be used to capture valuable metals such as gold.
[Images move through to show Justin swishing a sample of mercury, a close view of the mercury sample, and then Justin adjusting different gauges on equipment in a laboratory]
The use of mercury in artisanal and small-scale gold mining is extraordinarily harmful to both the miners and the environment.

More than 20 million subsistence miners use mercury to extract gold from ore.
[Images move through to show Justin and a colleague squatting down and unpacking equipment out of a tackle box, and then a side view of Justin putting on a pair of waterproof waders]
Our team has developed a number of solutions to address this issue.
[Images move through to show Justin walking toward the river, views of Justin and his colleague taking a water sample, the colleague labelling a sample, and Justin and the colleague in discussion]
We have mercury and cyanide free methods to extract and recover gold in a safer way, and we’ve also developed materials to capture the mercury pollution that has resulted from artisanal and small-scale gold mining.

Clean Earth Technologies has invested heavily in South Australia to get a plan up and running to produce this material.
[Images move through of Justin talking to the camera, Justin and a researcher in discussion, another colleague looking at a piece of rubber, and then Justin watching a female colleague work]
They anticipate investing upwards of $5 million over the next five years to support this manufacturing in South Australia, as well as employ scientists and engineers in this technology.

Over the next year our research is focussing on entirely new applications of our key materials.
[Camera zooms in on Justin taking a sample of rubber out and looking at it while in discussion with a colleague in a laboratory and then image changes to show a Justin talking to the camera]
These include new recyclable rubber, new plastics, new types of building materials that can ensure a sustainable built environment.

It’s an honour to be the recipient of the 2020 Prize for New Innovators.
[Image shows Justin looking at a sunset view and then the image changes to show Justin talking to the camera]
This award is a very humbling recognition of our work to translate academic discoveries into commercial products and services.
[Image changes to show a rock waterfall and then the image changes to show a side view of Justin looking up at the waterfall and around him]
I’m passionate about science and research because of the thrill of the discovery, the hunt to find things out.
[Image changes to show a side view of Justin talking to the camera and then the image changes to show Justin scooping out a sample of sand and adding it to a liquid in a laboratory]
In my field of chemistry I’m particularly attracted to the idea of building molecules and materials that have never existed before and then using them in applications that benefit humanity.
[Image changes to show Justin talking to the camera]
For aspiring scientists I would encourage you to stay curious, explore the world, and enjoy those discoveries. These are the true hallmarks of science.
