You will hear part of a discussion between two textile students about their research into sustainable fashion.
...:
First, you have some time to look at questions 21 to 24.
...:
Now listen carefully and answer questions 21 to 24.
STUDENT 1:
Shall we go through our research for our sustainable fashion project?
STUDENT 2:
I think I've done enough reading now.
STUDENT 1:
I've learnt such a lot about what sustainability actually means.
STUDENT 2:
Mmm, same for me with ethical fashion.
STUDENT 2:
I didn't really appreciate the difference between that and sustainable fashion before doing this research.
STUDENT 1:
Most people use these terms interchangeably, but in fact, the difference is quite distinct when you think about it.
STUDENT 1:
Sustainable relates to the environment, and ethical relates more to the way workers or animals are treated.
STUDENT 2:
I totally understand why people get confused, though.
STUDENT 2:
There are so many other terms used, like eco-friendly, which is actually quite meaningless.
STUDENT 1:
And the way companies use these terms when describing their products doesn't help.
STUDENT 1:
They're often deliberately vague, I think, and don't provide enough information about how their products are made.
STUDENT 1:
It was interesting to read about the debates surrounding wool production, and how ethical and sustainable that is.
STUDENT 1:
It's generally considered to be sustainable because it's a natural product.
STUDENT 2:
And it also lasts a long time and can be recycled.
STUDENT 2:
All very positive.
STUDENT 2:
But I wasn't convinced by the argument that wool production is sustainable because it doesn't use many chemicals.
STUDENT 2:
What about all the fungicides and insecticides used in sheep farming?
STUDENT 1:
And I couldn't find any evidence for the claim about sheep farming being better for the environment than cattle farming.
STUDENT 2:
No, they're both really bad.
STUDENT 2:
I read different reports about how unethical it is to even shear sheep.
STUDENT 2:
Some people say it's cruel, but as long as the sheep are kept in good condition, I can't see anything wrong with it.
...:
Before you hear the rest of the discussion, you have some time to look at questions 25 to 30.
...:
Now listen and answer questions 25 to 30.
STUDENT 2:
Shall we talk about some of the semi-synthetic new fabrics now?
STUDENT 1:
OK, let's do that.
STUDENT 2:
Let's start with lyacell.
STUDENT 2:
I've been reading about that.
STUDENT 1:
Yeah, that's the one produced from the pulp of eucalyptus trees, isn't it?
STUDENT 2:
And what happens with that is really impressive.
STUDENT 2:
Over 99% of dissolving agents used in the manufacturing process are used again.
STUDENT 1:
Now, there are a few semi-synthetic fabrics that I'd never heard of, like cupro, for example.
STUDENT 2:
Made from byproducts of the cotton industry to create a kind of vegan silk.
STUDENT 2:
But I'm not sure how sustainable this really is, as there are so many reports of pollution caused by the manufacturing process.
STUDENT 1:
It doesn't compare favorably with all the other sustainable fabrics we've looked at, no.
STUDENT 2:
Bamboo is one fabric we're all familiar with, but I didn't know that it was only organic bamboo that's truly sustainable.
STUDENT 1:
Apparently, the manufacturing process for a significant proportion of bamboo is chemically quite intensive, which obviously can be quite damaging.
STUDENT 2:
Ecoviral is an example of a semi-synthetic fabric which is becoming really popular.
STUDENT 1:
Probably because manufacturing causes 50% fewer emissions and takes up half as much energy as conventional fabrics.
STUDENT 1:
That saves production costs as well as being better for the environment.
STUDENT 2:
I think demand for cork will continue to grow.
STUDENT 2:
It works really well in vegan shoes and bags.
STUDENT 1:
And it's the only fabric that's fundamentally sustainable.
STUDENT 1:
The cork trees it comes from are renewable, and the product itself is both recyclable and biodegradable, which is unique.
STUDENT 2:
And the harvesting process is actually good for the trees.
STUDENT 2:
There are no downsides to using this source at all.
STUDENT 1:
Hemp is another really good sustainable fabric from a natural source.
STUDENT 2:
Did you know that clothes made from hemp protect the wearer from the sun?
STUDENT 2:
And it's also antibacterial.
STUDENT 1:
But I did read that it's quite hard to grow, so perhaps that's why it's not as common as you'd think.
STUDENT 2:
I'm sure that'll change.
STUDENT 2:
Then there are...
...:
That is the end of Part 3.

You now have 30 seconds to check your answers to Part 3.
