Headphones Made Of Fungus Could Change How We Use Plastic And Leather

August 29, 2019

These might be the most
groundbreaking headphones of all time. But not for the reasons you might expect. We’re not talking about audio capabilities or Bluetooth functionality, but rather what they’re made of. Fungus, bacteria, and yeast. It turns out, mushrooms and a whole
lot of other microbes can produce materials that
rival plastics and even leather. And there is a team of scientists and designers in Finland doing just that. So, how did they take such unusual materials and turn them into something
that could seriously shake up the world of product design? Nina Pulkkis: The Korvaa project started actually with frustration. Narrator: That’s Nina Pulkkis. She’s the one who started Korvaa, this whole headphone project. Pulkkis: I was filming for a documentary about microbes and synthetic biology. But I was really frustrated because I didn’t have very good samples of what you can actually do with microbes. Narrator: So she set out on a mission to see what could be made with them. She gathered a team of scientists, researchers, and designers to make it happen. Pulkkis: So, first of
all, we started to think, what kind of a product should we make. Géza Szilvay: There was
an idea about making a pair of headphones. Narrator: Headphones worked
for a couple of reasons. First, they are an instantly
recognizable product. Everyone has them. Second, they require lots of leathers and different kinds of plastics, and those aren’t always
sustainable materials. That’s because oil and natural gas are two of the main raw materials
used to make plastics. And in 2017, 368 million headphones
were sold worldwide, a number that’s expected to keep growing. That means a ton of plastic, leather, and synthetic leathers,
materials that rely heavily on nonrenewable,
nonbiodegradable resources. Korvaa’s process is a little different. To start out, the headband
is made of bioplastic. To make that bioplastic, the team uses plain old baker’s yeast. Through chemical processes,
they turn that yeast into a bioplastic substance. That substance gets
3D-printed and hardened. Next, the cushioned ear cups. These are made from fungal proteins and other plant-based
materials grown in the lab. Those materials get injected
right into this mold. And when they’re dry, they
look and feel just like foam. Szilvay: Then the ear-cup covers are made from fungal, leatherlike material. It’s made of mycelium. One could think of it as
root structure of mushrooms. Merja Penttilä: Fungi grow in so-called hyphal filamentous forms, so they form long, long stretches. So the material, in a way, grows itself. Narrator: And those
long stretches of roots will take the shape of
whatever you encourage them to. The result? Something similar to leather. To make the inner mesh part, the team created synthetic spider silk. Spider silk is superstrong,
lightweight, and elastic. But spiders can’t spin enough of it. So they make silk in the lab, without harming any
eight-legged creatures. By electro-spinning that silky
material onto a flat surface, they create a mesh material. Then, all those parts get pieced together to form a one-of-a-kind headset. Manuel Arias Barrantes: I think people have this perception that fungi is something, like, dangerous or, like, gross, because it grows on food also, that it’s rotten. But I think this is
slowly changing as more designers and companies are developing materials from natural sources. Saku Sysiö: For a lot of the materials, we didn’t know how to use them and how to make them work in this project. So that made it quite
challenging and interesting. Pulkkis: So it’s really exciting to see how this kind of small project grew into something really much, much bigger just by teaming up all
kinds of different people with different competencies and completely different backgrounds. Narrator: That team plans to commercialize these unique materials so they can be used in all sorts of products. Would you wear these fungus headphones?

  • Reply Nathan Woo August 28, 2019 at 10:33 am

    New renewable plastics are good but the reason we use fossil fuels is because they’re water proof, strong and light weight. We have pla but it lacks rigidity. And plant or kombucha leather seems more viable than fungus leather considering the labor and scale involved.
