Wombat:
All right. We're in Eco Town with ECO Block. I've got Daz. We're going to have a little bit of a chat about polystyrene and what you guys use it for, because I've got my little polystyrene poo, which I carry around with me. So this stuff here is actually the same as the sheeting that you guys use and it's melted down and this is how they recycle it. But I want to know what you guys use it for in the way of building side of things.

Daz:
We use it as a stay in place formwork, for reinforced concrete. So the panels are the formwork and a connector that goes in between, we can vary that connector to place our concrete. As you can see, we've got the steel in here, which is reinforcing that concrete. So we can engineer this to be a cyclone rated product or retaining walls or whatever.

Wombat:
So it's concrete on the inside.

Daz:
On the inside, yes.

Wombat:
Foam block on the outside.

Daz:
Correct.

Wombat:
So a bit different from SIPS panel, because it's foam on the inside and then then a sheeting on the outside.

Daz:
Yeah, that's right. Correct.

Wombat:
So you've actually got concrete foundation wall on the inside.

Daz:
Yes. It's the structural integrity of the building that is coming from that concrete.

Wombat:
And then what do you skim it with? I see you got a little bit of a display here.

Daz:
Sure. This is a polymer render that goes on to... It's actually a sand and cement bagged render that has a polymer in it, which actually sticks like [inaudible 00:01:16] to the polystyrene. So because it doesn't absorb moisture, it's a chemical bond from that to the polystyrene. But we're not limited to just rendering because our system has this web system that goes cast into the polystyrene in the manufacturing process, we can screw fix into this. So therefore we can clad these walls with cement sheet, corrugated iron, weatherboards.

Wombat:
Oh, really? So you can stick anything on the outside?

Daz:
Anything. And then that relates back onto the inside where we just screw and glue plasterboard.

Wombat:
Oh yeah. Finish it off.

Daz:
Because all those webs are every 200 millimetres along the block.

Wombat:
So the biggest thing I'm interested in, we had a bit of a chat about it already, and it's the amount that you can reduce what's going into the skip bin, because 45% of our landfill is actually building waste.

Daz:
Yes. All of my off cuts, which is very, very limited. It's only because of the architectural design that we might have a different size window. We'll have an off cut. Now, those offcuts, we put them in the bags and they go back to our refuse tip and they get melted down and re-processed so nothing is going into landfill. We've done homes here where they're two and three story homes with no skip bin onsite.

Wombat:
Really?

Daz:
No builder's bin on site.

Wombat:
That's awesome.

Daz:
Yes, because we're taking that away to the recycling and it's getting reprocessed again.

Wombat:
And that's why you have eco in front of block.

Daz:
Exactly. Exactly.

Wombat:
No worries, mate. Thanks for the chat.

Daz:
Thank you.

Wombat:
Cheers.

Daz:
Thank you. Lovely to meet you. Cheers.
