And you may have thrown a bit of a clue in there, Claire, around decarbonising things.


So what were the innovation questions that you were trying to get around? And The supplementary question is why Australia versus Europe or other parts of the world who I assume have similar challenges?

And so globally, there is an organisation called the Global Cement and Concrete Association.

And these are definitely conversations that are happening at that inter-country level.

Why is this urgency around the climate crisis that we're facing at the moment.

So concrete is classified as a heavy industry and that's specifically because of the production of cement.

For anyone who was on my journey, just to tell you quickly, cement is the grey powder that you mix into the wet concrete mix and concrete is then what dries to form the structures.

So the process is that we quarry limestone and then we burn that limestone in a kiln at 1450 degrees.

So that's kind of problem number one is we need to generate heat at that temperature.

At the moment, the only way that we have to generate that temperature is by burning things.

But then the next issue is that when this clinkerization process happens, when you burn that limestone and then it goes into quicklime, which turns into cement, it actually releases the CO2.
