This machine is churning out leather - but instead of animal skin, it's made from pineapple skin.
Fashion students at London's Royal College of Art are showcasing their sustainable collection - featuring handbags made of ice cube trays (SOUNDBITE) (English) STUDENT DESIGNER, ANDREW BELL, SAYING: "Fashion and sustainability have to now be one.
You have to be thinking in different ways.
Fashion has been doing the same thing for so long.
We've created the same black top and the same black jeans, and we're constantly calling them new - the same white T-shirts.
There's actually nothing new about these items, and that's what's really exciting about the RCA, it's about challenging what can be new, what are new ways, new methodologies of making." One of the ways these young designers want to cut waste is by reducing the number of materials they use... (SOUNDBITE) (English) STUDENT DESIGNER, MARGOT VAADERPASS, SAYING: "So what's the value in designing with more of the same material in some piece?
It's that it's more recyclable and it's also more biodegradable than that (other) garment." This student has a vision for people growing their own garments with slime mould.
The living organism is applied on his pre-designed patterns, and can grow up to a centimeter per hour.
(SOUNDBITE) (English) STUDENT DESIGNER PIERO D'ANGELO, SAYING: "We designed a 3D printed prototype and if you can see on the prototype there are holes and that's the place where we put food sources so once we apply the slime mould it will just grow, spread all over, connecting each one of those holes." Larger big name fashion houses have been pushing their environmental creds in recent years.
So while you might not be rushing to grow your own slime jacket just yet, some of these ideas could be part of the future of sustainable fashion.
