So, I'd like to spend a few minutes with you folks today

3000
我希望花几分钟时间和你们聊聊
00:18
imagining what our planet might look like in a thousand years.
1
3000
3000
想象下一千年以后我们的星球看起来会是怎样的？
00:21
But before I do that,
2
6000
2000
但在这之前，
00:23
I need to talk to you about synthetic materials like plastics,
3
8000
3000
我需要告诉你像塑料这样的花费巨大的
00:26
which require huge amounts of energy to create
4
11000
3000
人力物力来制造的合成材料，
00:29
and, because of their disposal issues,
5
14000
2000
因为它们存在的废弃处理问题，
00:31
are slowly poisoning our planet.
6
16000
2000
正在逐渐毒害我们的地球。
00:33
I also want to tell you and share with you
7
18000
2000
我也想与大家分享
00:35
how my team and I
8
20000
2000
我和我的团队
00:37
have been using mushrooms over the last three years.
9
22000
3000
如何在过去的三年中使用蘑菇。
00:40
Not like that. (Laughter)
10
25000
2000
不是那样子（笑声）
00:42
We're using mushrooms to create an entirely new class of materials,
11
27000
3000
我们正使用蘑菇来创造一种全新的材料。
00:45
which perform a lot like plastics during their use,
12
30000
3000
使用起来和塑料一样，
00:48
but are made from crop waste
13
33000
2000
但是是以农作物废料来制造的
00:50
and are totally compostable at the end of their lives.
14
35000
3000
并且在他们的使用寿命结束后完全降解于大自然中。
00:53
(Cheering)
15
38000
2000
（欢呼）
00:55
But first,
16
40000
2000
但首先，
00:57
I need to talk to you about what I consider one of the most egregious offenders
17
42000
3000
我需要和大家聊下我认为在
01:00
in the disposable plastics category.
18
45000
2000
可降解塑料中最差的品种。
01:02
This is a material you all know is Styrofoam,
19
47000
2000
你们都知道有一种叫做泡沫塑料的材料，
01:04
but I like to think of it as toxic white stuff.
20
49000
3000
我认为这种一种白色污染。
01:08
In a single cubic foot of this material --
21
53000
2000
当你购买电脑或者大尺寸的电视机
01:10
about what would come around your computer or large television --
22
55000
2000
大约会带有一立方英尺的泡沫塑料－
01:12
you have the same energy content
23
57000
2000
它们对能源的消耗相当于
01:14
of about a liter and a half of petrol.
24
59000
2000
一升半的石油。
01:16
Yet, after just a few weeks of use,
25
61000
2000
经过几周后的使用，
01:18
you'll throw this material in the trash.
26
63000
3000
你把这玩艺扔进了垃圾筒，
01:21
And this isn't just found in packaging.
27
66000
2000
它们不仅仅被用作包装材料。
01:23
20 billion dollars of this material is produced every year,
28
68000
2000
每年大约200亿美元的泡沫塑料被生产出来，
01:25
in everything from building materials to surfboards
29
70000
3000
用来制造各种产品包括建材，冲浪板
01:28
to coffee cups to table tops.
30
73000
2000
到咖啡杯和桌面。
01:30
And that's not the only place it's found.
31
75000
3000
它们也不仅仅只出现在这些产品中。
01:33
The EPA estimates, in the United States,
32
78000
2000
根据环保署的估算，在美国，
01:35
by volume, this material occupies 25 percent of our landfills.
33
80000
3000
按体积来算，这种材料占据了4分之一的垃圾填埋场。
01:39
Even worse is when it finds its way into our natural environment --
34
84000
3000
更糟糕的是当它进入我们的自然环境－
01:42
on the side of the road or next to a river.
35
87000
2000
出现在路边或者河边。
01:44
If it's not picked up by a human, like me and you,
36
89000
3000
如果不被人回收，比如我们，
01:47
it'll stay there for thousands and thousands of years.
37
92000
2000
它就会再那待上成千上万年。
01:49
Perhaps even worse
38
94000
2000
更坏的情况是
01:51
is when it finds its way into our oceans, like in the great plastic gyre,
39
96000
3000
当它们进入到海洋中，就好像太平洋上的庞大的塑料漩涡，
01:54
where these materials are being mechanically broken
40
99000
2000
这些材料被机械化地
01:56
into smaller and smaller bits,
41
101000
2000
粉碎成无数小碎片，
01:58
but they're not really going away.
42
103000
2000
但是它们并没有消失。
02:00
They're not biologically compatible.
43
105000
2000
它们也不与自然兼容。
02:02
They're basically fouling up
44
107000
2000
它们基本上就是在堵塞
02:04
Earth's respiratory and circulatory systems.
45
109000
2000
地球的呼吸循环系统。
02:06
And because these materials are so prolific,
46
111000
3000
这些材料的量太大了，
02:09
because they're found in so many places,
47
114000
2000
它们几乎无所不在，
02:11
there's one other place you'll find this material, styrene,
48
116000
3000
还有一个地方你会发现这种材料，苯乙烯
02:14
which is made from benzene, a known carcinogen.
49
119000
2000
它是由苯制成，一种已知的致癌物。
02:16
You'll find it inside of you.
50
121000
3000
你会在你自己的身体里发现它。
02:19
So, for all these reasons,
51
124000
2000
由于这些原因，
02:21
I think we need better materials,
52
126000
2000
我认为我们需要更好的材料，
02:23
and there are three key principles we can use to guide these materials.
53
128000
3000
对这些材料我们有三个关键的原则。
02:27
The first is feedstocks.
54
132000
2000
首先是原料。
02:29
Today, we use a single feedstock, petroleum,
55
134000
3000
今天我们使用单一的原料，石油，
02:32
to heat our homes, power our cars
56
137000
2000
来加热房间，驱动车辆
02:34
and make most of the materials you see around you.
57
139000
3000
制造绝大多数你周围的东西。
02:37
We recognize this is a finite resource,
58
142000
2000
我们明白这是一种有限的资源，
02:39
and it's simply crazy to do this, to put a liter and a half of petrol in the trash
59
144000
3000
而每次你拿到一个包装就把一升半的
02:42
every time you get a package.
60
147000
2000
石油扔进垃圾筒也很疯狂。
02:44
Second of all, we should really strive to use far less energy
61
149000
2000
第二，我们真的需要大量减少
02:46
in creating these materials.
62
151000
2000
用来制造这些材料的能源。
02:48
I say far less, because 10 percent isn't going to cut it.
63
153000
3000
我说大量减少，因为10％不会起什么大作用。
02:51
We should be talking about half, a quarter,
64
156000
2000
我们应该起码讲一半，或者四分之一，
02:53
one-tenth the energy content.
65
158000
3000
甚至十分之一。
02:56
And lastly, and I think perhaps most importantly,
66
161000
3000
最后，我认为可能最重要的是，
02:59
we should be creating materials
67
164000
2000
我们应该创造能够适合
03:01
that fit into what I call nature's recycling system.
68
166000
3000
自然循环系统的材料。
03:04
This recycling system has been in place for the last billion years.
69
169000
3000
这循环系统已经存在了上亿年的时间。
03:07
I fit into it, you fit into it,
70
172000
2000
我能溶解于其中，你也可以，
03:09
and a hundred years tops, my body can return to the Earth with no preprocessing.
71
174000
3000
一百年以后，我的身体可以不用处理就回归到地球。
03:12
Yet that packaging I got in the mail yesterday
72
177000
2000
而我昨天收到的邮件包装
03:14
is going to last for thousands of years.
73
179000
2000
则会待上千年。
03:16
This is crazy.
74
181000
2000
这太夸张了。
03:18
But nature provides us with a really good model here.
75
183000
3000
但是自然给我们提供了一个非常好的模范。
03:21
When a tree's done using its leaves --
76
186000
2000
当一个树使用了它的叶子－
03:23
its solar collectors, these amazing molecular photon capturing devices --
77
188000
3000
它的太阳能收集器，这些了不起的分子大小的光子捕获设备－
03:26
at the end of a season,
78
191000
2000
在季末的时候，
03:28
it doesn't pack them up, take them to the leaf reprocessing center
79
193000
3000
它没有把叶子包装好，送到一个树叶处理中心
03:31
and have them melted down to form new leaves.
80
196000
2000
溶解它们来制造新的树叶。
03:33
It just drops them, the shortest distance possible,
81
198000
3000
它仅仅是让叶子掉落，
03:36
to the forest floor,
82
201000
2000
这是到达地面最短的距离，
03:38
where they're actually upcycled into next year's topsoil.
83
203000
2000
在那里它们会再循环进入明年的表层土壤。
03:40
And this gets us back to the mushrooms.
84
205000
3000
让我们回到蘑菇。
03:44
Because in nature,
85
209000
2000
因为在大自然中，
03:46
mushrooms are the recycling system.
86
211000
2000
蘑菇是循环系统。
03:48
And what we've discovered
87
213000
2000
我们发现的是
03:50
is, by using a part of the mushroom you've probably never seen --
88
215000
2000
使用蘑菇身上你可能从来没看见过的一部分－
03:52
analogous to its root structure; it's called mycelium --
89
217000
3000
类似它的根结构，叫做菌丝体－
03:55
we can actually grow materials
90
220000
2000
我们可以生长出和传统
03:57
with many of the same properties of conventional synthetics.
91
222000
3000
合成材料有着相同属性的材料。
04:00
Now, mycelium is an amazing material,
92
225000
2000
菌丝体是一种很棒的材料，
04:02
because it's a self-assembling material.
93
227000
2000
因为它是一种自我组合材料。
04:04
It actually takes things we would consider waste --
94
229000
2000
它将被我们认为是废料的－
04:06
things like seed husks or woody biomass --
95
231000
3000
比如种子外壳或者木质生物质－
04:09
and can transform them into a chitinous polymer,
96
234000
2000
转化成角质状的聚合物，
04:11
which you can form into almost any shape.
97
236000
2000
这种聚合物可以被加工成任何形状。
04:13
In our process,
98
238000
2000
在我们的流程中，
04:15
we basically use it as a glue.
99
240000
2000
我们把它当作黏合剂来使用。
04:17
And by using mycelium as a glue,
100
242000
2000
通过使用菌丝体作为黏合剂，
04:19
you can mold things just like you do in the plastic industry,
101
244000
3000
就可以像在塑料行业一样把东西塑造成任何形状，
04:22
and you can create materials with many different properties,
102
247000
3000
可以创造许多种不同属性的材料，
04:25
materials that are insulating, fire-resistant,
103
250000
3000
隔音的，防火的，
04:28
moisture-resistant, vapor-resistant --
104
253000
3000
防潮的，防蒸汽的－
04:31
materials that can absorb impacts, that can absorb acoustical impacts.
105
256000
3000
防震的，还有消音的材料。
04:34
But these materials are grown from agricultural byproducts,
106
259000
3000
不过它们全都是从农作物副产品中生长出来的，
04:37
not petroleum.
107
262000
2000
而不是石油，
04:39
And because they're made of natural materials,
108
264000
3000
因为它们是用天然材料制成，
04:42
they are 100 percent compostable
109
267000
2000
它们是百分之百可以
04:44
in you own backyard.
110
269000
2000
在你的后院降解的。
04:47
So I'd like to share with you the four basic steps
111
272000
2000
我想要和大家分享制造这些材料
04:49
required to make these materials.
112
274000
2000
所需的4个基本步骤。
04:51
The first is selecting a feedstock,
113
276000
2000
首先是选择原料，
04:53
preferably something that's regional, that's in your area, right --
114
278000
2000
最好是本地的，在你的区域就可以获得－
04:55
local manufacturing.
115
280000
2000
本地制造。
04:57
The next is actually taking this feedstock and putting in a tool,
116
282000
3000
下一步把这些原料放进一个工具，
05:00
physically filling an enclosure, a mold,
117
285000
2000
把它们填进一个模具，
05:02
in whatever shape you want to get.
118
287000
2000
可以是你希望的任何形状。
05:04
Then you actually grow the mycelium through these particles,
119
289000
3000
接着就从这些粒子中生长出菌丝体，
05:07
and that's where the magic happens,
120
292000
2000
这就是魔法发生的地方，
05:09
because the organism is doing the work in this process,
121
294000
2000
因为这个过程中主要是这些生物自己在工作，
05:11
not the equipment.
122
296000
2000
而不是设备，
05:13
The final step is, of course, the product,
123
298000
2000
最后一部，当然就是形成最终产品，
05:15
whether it's a packaging material, a table top, or building block.
124
300000
3000
无论它是包装材料，桌面，还是建材。
05:18
Our vision is local manufacturing,
125
303000
2000
我们的愿景是本地化的制造，
05:20
like the local food movement, for production.
126
305000
2000
就像本地食物运输那样生产。
05:22
So we've created formulations for all around the world
127
307000
2000
我们开发了利用全世界各地的不同的
05:24
using regional byproducts.
128
309000
2000
农作副产品的生产模式。
05:26
If you're in China, you might use a rice husk
129
311000
3000
如果你在中国，你可以使用稻壳
05:29
or a cottonseed hull.
130
314000
2000
或者棉籽壳。
05:31
If you're in Northern Europe or North America,
131
316000
2000
如果你在北欧或者北美，
05:33
you can use things like buckwheat husks or oat hulls.
132
318000
3000
可以用荞麦皮或者燕麦皮。
05:37
We then process these husks with some basic equipment.
133
322000
3000
接着利用一些基本的设备来处理这些谷壳。
05:40
And I want to share with you a quick video from our facility
134
325000
2000
我想与你们分享一段在我们的厂房拍摄的短片
05:42
that gives you a sense of how this looks at scale.
135
327000
3000
能让你感受一下实际的规模。
05:45
So what you're seeing here is actually cotton hulls from Texas, in this case.
136
330000
3000
你所看见的实际上是德州的棉籽壳。
05:48
It's a waste product.
137
333000
2000
这些是生产废料。
05:50
And what they're doing in our equipment
138
335000
2000
它们在这些设备中，
05:52
is going through a continuous system,
139
337000
2000
经过一个连续的系统，
05:54
which cleans, cooks, cools
140
339000
3000
清洁，烧煮，冷却，
05:57
and pasteurizes these materials,
141
342000
2000
对其使用使用巴氏消毒法消毒。
05:59
while also continuously inoculating them with our mycelium.
142
344000
3000
并不断将它们与我们的菌丝体接种。
06:02
This gives us a continuous stream of material
143
347000
2000
这个流程提供给我们一个持续性的材料源
06:04
that we can put into almost any shape,
144
349000
2000
我们可以把它放进任何形状，
06:06
though today we're making corner blocks.
145
351000
2000
今天我们所做的是角块。
06:08
And it's when this lid goes on the part,
146
353000
2000
当把盖子掀开的时候，
06:10
that the magic really starts.
147
355000
3000
魔法便开始了。
06:13
Because the manufacturing process is our organism.
148
358000
3000
因为这个加工过程是这些生物。
06:16
It'll actually begin to digest these wastes
149
361000
2000
它们开始消化这些废料
06:18
and, over the next five days,
150
363000
2000
然后在接下来的五天里面，
06:20
assemble them into biocomposites.
151
365000
3000
将它们组织成生物复合材料。
06:23
Our entire facility
152
368000
2000
我们整个厂房
06:25
is comprised of thousands and thousands and thousands of these tools
153
370000
3000
由千千万万这样的工具组成。
06:28
sitting indoors in the dark, quietly self-assembling materials --
154
373000
3000
它们在黑暗中安静地进行着材料地自我组装－
06:31
and everything from building materials
155
376000
2000
所有材料，从建筑材料到
06:33
to, in this case,
156
378000
2000
在这个案例中，
06:35
a packaging corner block.
157
380000
2000
包装用的角块。
06:37
So I've said a number of times that we grow materials.
158
382000
3000
我几次提到我们是生长材料。
06:40
And it's kind of hard to picture how that happens.
159
385000
2000
不过具体发生了什么还有点难以描述。
06:42
So my team has taken five days-worth of growth,
160
387000
2000
所以我的团队
06:44
a typical growth cycle for us,
161
389000
2000
把典型的5天生长周期，
06:46
and condensed it into a 15-second time lapse.
162
391000
3000
压缩到一段15秒的短片中。
06:49
And I want you to really watch closely
163
394000
2000
我希望大家仔细地看
06:51
these little white dots on the screen,
164
396000
2000
这些屏幕上的白色小斑点，
06:53
because, over the five-day period,
165
398000
2000
因为在5天里面，
06:55
what they do is extend out and through this material,
166
400000
3000
它们将扩展至整个材料，
06:58
using the energy that's contained in these seed husks
167
403000
2000
利用这些谷壳里所包含的能量
07:00
to build this chitinous polymer matrix.
168
405000
2000
来建造这个角质聚合物。
07:02
This matrix self-assembles,
169
407000
2000
这种混合物会自行组合，
07:04
growing through and around the particles,
170
409000
2000
在这些白点周围生长，
07:06
making millions and millions of tiny fibers.
171
411000
3000
生成数百万的微小的纤维。
07:09
And what parts of the seed husk we don't digest,
172
414000
3000
而没有消化掉的种壳，
07:12
actually become part of the final, physical composite.
173
417000
3000
最终也变成了复合物的一部分。
07:15
So in front of your eyes, this part just self-assembled.
174
420000
2000
所以大家眼前看到的，是这部分刚刚完成自我组合。
07:17
It actually takes a little longer. It takes five days.
175
422000
3000
实际过程会长一点，需要5天。
07:20
But it's much faster than conventional farming.
176
425000
3000
但是比传统的农业耕作要快很多。
07:23
The last step, of course, is application.
177
428000
2000
最后一步，当然就是应用了。
07:25
In this case, we've grown a corner block.
178
430000
2000
在这个例子中，我们生长出了一个角块。
07:27
A major Fortune 500 furniture maker
179
432000
3000
一个财富500强的家具商
07:30
uses these corner blocks to protect their tables in shipment.
180
435000
3000
用这些角块来保护装运过程中的桌子。
07:33
They used to use a plastic packaging buffer,
181
438000
2000
过去它们使用的是一种塑料缓冲包装，
07:35
but we were able to give them the exact same physical performance
182
440000
3000
不过用我们的材料可以提供
07:38
with our grown material.
183
443000
2000
与这些塑料一样的物理性能。
07:40
Best of all, when it gets to the customer,
184
445000
3000
最棒的是，当顾客收到产品，
07:43
it's not trash.
185
448000
2000
它们也不是垃圾。
07:45
They can actually put this in their natural ecosystem without any processing,
186
450000
2000
它们可以无需任何处理就放进当地生态系统中，
07:47
and it's going to improve the local soil.
187
452000
2000
改善当地土壤质量。
07:49
So, why mycelium?
188
454000
2000
那么，为什么是菌丝体？
07:51
The first reason is local open feedstocks.
189
456000
2000
第一个原因是在本地开放性地获取原料。
07:53
You want to be able to do this anywhere in the world
190
458000
2000
我们希望能在全世界任何地方开展生产
07:55
and not worry about peak rice hull or peak cottonseed hulls,
191
460000
2000
而不用担心稻壳或棉籽壳价格攀升，
07:57
because you have multiple choices.
192
462000
2000
因为有多种选择。
07:59
The next is self-assembly,
193
464000
2000
第二是自我组合，
08:01
because the organism is actually doing most of the work in this process.
194
466000
3000
因为有机微生物担任着整个过程中的绝大部分工作。
08:04
You don't need a lot of equipment to set up a production facility.
195
469000
3000
你不需要太多的设备来建立一个生产中心。
08:07
So you can have lots of small facilities
196
472000
2000
所以我们可以在全世界
08:09
spread all across the world.
197
474000
2000
设立许多小的厂房。
08:11
Biological yield is really important.
198
476000
2000
生物产量是很重要的，
08:13
And because 100 percent of what we put in the tool become the final product,
199
478000
3000
因为所有我们放进工具的原料都变成了最终产品，
08:16
even the parts that aren't digested
200
481000
2000
甚至没有消化的部分
08:18
become part of the structure,
201
483000
2000
也变成了结构的一部分，
08:20
we're getting incredible yield rates.
202
485000
2000
因此我们获得了惊人的收益率。
08:22
Natural polymers, well ... I think that's what's most important,
203
487000
3000
天然聚合物，我认为这是最最重要的，
08:25
because these polymers have been tried and tested
204
490000
2000
因为这些聚合物已经在过去的10亿年里，
08:27
in our ecosystem for the last billion years,
205
492000
2000
在我们的生态系统中经历过考验，
08:29
in everything from mushrooms to crustaceans.
206
494000
3000
从蘑菇到甲壳类的任何生物。
08:32
They're not going to clog up Earth's ecosystems. They work great.
207
497000
3000
它们不会堵塞地球的循环系统，它们一直都很适用。
08:35
And while, today,
208
500000
2000
与此同时，今天，
08:37
we can practically guarantee that yesterday's packaging
209
502000
2000
我们能很肯定的说过去的包装
08:39
is going to be here in 10,000 years,
210
504000
2000
会持续10000年之久，
08:41
what I want to guarantee
211
506000
2000
我想保证的是
08:43
is that in 10,000 years,
212
508000
2000
在10000年里，
08:45
our descendants, our children's children,
213
510000
2000
我们的后代，我们的孩子的孩子
08:47
will be living happily and in harmony
214
512000
3000
会快乐和谐地生活在
08:50
with a healthy Earth.
215
515000
2000
一个健康地地球上。
08:52
And I think that can be some really good news.
216
517000
2000
而且我觉得这会是非常好的消息。
08:54
Thank you.
217
519000
2000
谢谢
08:56
(Applause)

ABOUT THE SPEAKER
Eben Bayer - Green designerEben Bayer is co-inventor of MycoBond, an organic (really -- it's based on mycelium, a living, growing organism) adhesive that turns agriwaste into a foam-like material for packaging and insulation.
Why you should listen
As co-founder of Ecovative, Eben Bayer co-invented MycoBond, a technology that uses a filamentous fungi to transform agricultural waste products into strong composite materials. Or, as CNN put it: "In non-scientific terms, they grind up seed husks and glue the small pieces together with mushroom root." Their products include packaging and styrofoam substitute and the now-in-development Greensulate rigid insulation board for builders. Both products require less energy to create than synthetics like foam, because they're quite literally grown. Equally compelling, at the end of their useful life, they can be home-composted or even used as garden mulch.
