01/20

✤ So, I’d like to spend uh a few minutes with you folks today

[1. imagining] what our planet might look like in a thousand years.

✤ But before I do that, I need to talk to you about synthetic

materials like plastics, which require huge amounts of energy to create and, because of their disposal issues, are slowly [2. poisoning] our planet.

✤ I also want to tell you, and share with you, how my team

and I have been using mushrooms over the last three years.

Thursday, December 1, 2011

02/20

✤ Huh, not like that. (Laughter) We’re using mushrooms to

create an entirely new class of materials, which perform a lot like [3. plastics] during their use, but are made from crop waste and are totally compostable at the end of their lives.

✤ But first, I need to talk to you about what I consider one

• f the most egregious offenders in the disposable plastics
• category. This is a material you all know as Styrofoam,

but I like to think of it as [4. toxic] white stuff.

Thursday, December 1, 2011

03/20

✤ And in a single cubic foot of this material —about what

would come around your computer or large television — you have the same energy content of about a liter and a half of petrol. Yet, after just a few weeks of use, you’ll throw this material in the [5. trash]. And this isn’t just found in packaging. 20 billion dollars of this material is produced every year, in everything from building materials to surfboards to coffee cups to table tops. And that’s not the only place it’s found.

Thursday, December 1, 2011

04/20

✤ The EPA estimates, in the United States, by volume, this

material occupies 25 percent of our landfills. Even worse is when it [6. finds] its way into our natural environment —on the side of the road or next to a river. If it’s not picked up by a human, like me and you, it’ll stay there for thousands and thousands of years.

✤ Perhaps even worse is when it finds its way into our oceans,

like in the great plastic gyre, where these materials are being mechanically broken into smaller and smaller bits, but they’re not really going away.

Thursday, December 1, 2011

05/20

✤ They’re not biologically [7. compatible]. They’re

basically fouling up Earth’s respiratory and circulatory systems.

✤ And because these materials are so prolific, because

they’re found in so many places, there’s one other place you’ll find this material, styrene, which is made from [8. benzene], a known carcinogen. You’ll find it inside of you.

Thursday, December 1, 2011

06/20

✤ So, for all these reasons, I think we need better materials,

and there are three key principles we can use to guide these materials.

✤ The first is feed-stocks. Today, we use a single feed-stock,

petroleum, to heat our homes, [9. power] our cars and make most of the materials you see around you. We recognize this is a finite resource, and it’s simply crazy to do this, to put a liter and a half of petrol in the trash every time you get a package.

Thursday, December 1, 2011

07/20

✤ Second of all, we should really strive to use far less energy

in creating these materials. I say far less, because 10 percent isn’t gonna cut it. We should be [10. talking] about half, a quarter, one-tenth the energy content.

✤ And lastly, and I think perhaps most importantly, we should

be creating materials that fit into what I call nature’s recycling

• system. This recycling system has been in place for the last

billion years. I fit into it, you fit into it, and a hundred years tops, my body can return to the Earth with no preprocessing.

Thursday, December 1, 2011

08/20

✤ Yet that [11. packaging] I got in the mail yesterday is going

to last for thousands of years, right? This is crazy.

✤ But nature provides us with a really good model here.

When a tree’s done using its leaves —its solar collectors, these amazing [12 .molecular] photon capturing devices — at the end of a season, it doesn’t pack them up, take them to the leaf reprocessing center and have them melted down to form new leaves. It just drops them, the shortest distance possible, to the forest floor, where they’re actually upcycled into next year’s topsoil.

Thursday, December 1, 2011

09/20

✤ And this gets us back to the mushrooms. Because in

nature, [13. mushrooms] are the recycling system. And what we’ve discovered is, by using a part of the mushroom you’ve probably never seen —analogous to its root structure; it’s called mycelium —we can actually [14. grow] materials with many of the same properties

• f conventional synthetics.

Thursday, December 1, 2011

10/20

✤ Now, mycelium is an amazing material, because it’s a

self-assembling material. It actually takes things we would consider waste —things like seed husks or woody [15. biomass] —and can transform them into a chitinous polymer, which you can form into almost any shape. In

• ur process, we basically use it as a glue.

Thursday, December 1, 2011

11/20

✤ And by using mycelium as a glue, you can mold things just

like you do in the plastic industry, and you can create materials with many different properties: materials that are insulating, fire-resistant, moisture-resistant, [16. vapor- resistant] —materials that can absorb impacts, that can absorb acoustical impacts.

✤ But these materials are grown from agricultural by-

products, not made out of petroleum. And because they’re made of natural materials, they are 100 percent compostable in you own backyard.

Thursday, December 1, 2011

12/20

✤ So I’d like to share with you the four basic steps required to

make these [17. materials]. The first is selecting a feed-stock, preferably something that’s regional, that’s in your area, right —local manufacturing. The next is actually taking this feed-stock and putting in a tool, physically filling an enclosure, a mold, in whatever shape you want to get. Then you actually grow the mycelium through these particles, and that’s where the magic happens, ’cause the [18. organism] is doing the work in this process, not the equipment. The final step is, of course, the product, whether it’s a packaging material, a table top, or a building block.

Thursday, December 1, 2011

13/20

✤ Our vision is local manufacturing, like the local food

movement, for production. So we’ve created formulations for all around the world using regional [19. by-products].

✤ If you’re in China, you might use a rice husk or a

cottonseed hull. If you’re in Northern Europe or North America, you can use things like buckwheat husks or oat

• hulls. We then process these husks with some basic
• equipment. And I wanna [20. share] with you a quick video

from our facility that gives you a sense of how this looks at scale.

Thursday, December 1, 2011

14/20

✤ So what you’re seeing here is actually cotton hulls from

Texas, in this case. So [it’s] a waste product. And what they’re doing in our equipment is going through a continuous system, which cleans, cooks, cools and [21. pasteurizes] these materials, while also continuously inoculating them with our mycelium. This gives us a continuous stream of material that we can put into almost any shape, though. Today we’re making corner

• blocks. And it’s when this lid goes on the part, that the

magic really starts.

Thursday, December 1, 2011

15/20

✤ Because the main manufacturing [22. process] is our

• rganism. It’ll actually begin to digest these ag— wastes

and, over the next five days, assemble them into

• biocomposites. Our entire facility is comprised of

thousands and thousands and thousands of these tools sitting indoors in the dark, quietly self-assembling materials —and everything from building materials to, in this case, a packaging corner block.

Thursday, December 1, 2011

16/20

✤ So I’ve said a number of times that we grow materials. And

it’s kind of hard to picture how that happens. So my team has taken five days-worth of growth, a typical growth [23. cycle] for us, and condensed it into a 15-second time lapse.

✤ And I want you to really watch closely these little white

dots on the screen, because, over the five-day period, what they do is extend out and through this material, using the energy that’s contained in these seed husks to build this chitinous polymer matrix.

Thursday, December 1, 2011

17/20

✤ This matrix self-assembles, growing through and around the

particles, making millions and millions of tiny fibers. And what parts of the seed husk we don’t [24. digest], actually become part

• f the final, physical composite. So in front of your eyes, this part

just self-assembled. It actually takes a lot —a little longer. It takes five days. Uh but it’s much faster than conventional farming.

✤ The last step, of course, is application. In this case, we’ve grown a

corner block. A major Fortune 500 furniture —a maker [25. uses] these corner blocks to protect their tables in shipment. They used to use a plastic packaging buffer, but we were able to give them the exact same physical performance with our grown material.

Thursday, December 1, 2011

18/20

✤ Best of all, when it gets to the customer, it’s not trash,

right? They can actually put this in their natural ecosystem without any processing, and it’s goinna [26. improve] the local soil.

✤ So, why mycelium? The first reason is local open feed-

• stocks. You wanna be able to do this anywhere in the

world and not worry about peak rice hull or peak cottonseed hulls, because you have multiple choices.

Thursday, December 1, 2011

19/20

✤ The next is self-assembly, because the organism is

actually doing most of the work in this process. You don’t need a lot of equipment to set up a production

• facility. So you can have lots of small facilities [27.

spread] all across the world.

✤ Biological yield is really important. And because 100

percent of what we have put in the tool become the final product, even the parts that aren’t digested become part

• f the structure, we’re getting [28. incredible] yield rates.

Thursday, December 1, 2011

20/20

✤ Natural polymers —well, I think that’s what’s most important,

because these polymers have been tried and tested in our ecosystem for the last billion years, in everything from mushrooms to crustaceans. They’re not going to clog up Earth’s [29. ecosystems]. They work great. And while, today, we can practically guarantee that yesterday’s packaging is going to be here in 10,000 years, and what I wanna guarantee is that in 10,000 years, our descendants, our children’s children, will be living happily and in harmony with the healthy Earth.

✤ And I think that can be [30. some] really good news. Thank you.

(Applause)
