So, I'd like to spend a few minutes with you folks today
0
0
3000
我想和各位度過幾分鐘
00:18
imagining what our planet might look like in a thousand years.
1
3000
3000
想像我們一千年後的地球
00:21
But before I do that,
2
6000
2000
但，在這之前
00:23
I need to talk to you about synthetic materials like plastics,
3
8000
3000
我要說說有關合成材料的事
00:26
which require huge amounts of energy to create
4
11000
3000
創造合成材料需要消耗極大的能量
00:29
and, because of their disposal issues,
5
14000
2000
由於處置它們的問題
00:31
are slowly poisoning our planet.
6
16000
2000
我們的地球正漸漸遭受毒害
00:33
I also want to tell you and share with you
7
18000
2000
我也想告訴你們並和你們分享:
00:35
how my team and I
8
20000
2000
我和我的團隊
00:37
have been using mushrooms over the last three years.
9
22000
3000
在過去三年來，已使用蘑菇
00:40
Not like that. (Laughter)
10
25000
2000
不是利用它們的迷幻成份（笑聲）
00:42
We're using mushrooms to create an entirely new class of materials,
11
27000
3000
我們用蘑菇創造出一種全新的材料
00:45
which perform a lot like plastics during their use,
12
30000
3000
它用起來和塑膠相當
00:48
but are made from crop waste
13
33000
2000
但卻是由農作物廢料所製成的
00:50
and are totally compostable at the end of their lives.
14
35000
3000
而且在丟棄時可以完全分解
00:53
(Cheering)
15
38000
2000
（歡呼聲）
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
我必須告訴各位，在一次性塑料類別中
01:00
in the disposable plastics category.
18
45000
2000
我所認為最糟糕的東西是什麽。
01:02
This is a material you all know is Styrofoam,
19
47000
2000
這是你們都知道的材料: 發泡膠
01:04
but I like to think of it as toxic white stuff.
20
49000
3000
我認為它比較像一種有毒的白色物質
01:08
In a single cubic foot of this material --
21
53000
2000
每單位立方英尺的這種材料 --
01:10
about what would come around your computer or large television --
22
55000
2000
會出現在你的電腦或大電視的這一材料 --
01:12
you have the same energy content
23
57000
2000
能源的內容，大約相當於
01:14
of about a liter and a half of petrol.
24
59000
2000
1.5公升的石油
01:16
Yet, after just a few weeks of use,
25
61000
2000
然而，在幾個星期的使用後
01:18
you'll throw this material in the trash.
26
63000
3000
你會把這東西丟進垃圾桶
01:21
And this isn't just found in packaging.
27
66000
2000
它不只出現於包裝
01:23
20 billion dollars of this material is produced every year,
28
68000
2000
每年有價值 200 億美元的材料被製造出來
01:25
in everything from building materials to surfboards
29
70000
3000
從建築材料到衝浪板
01:28
to coffee cups to table tops.
30
73000
2000
從咖啡杯到桌子，包含了所有東西
01:30
And that's not the only place it's found.
31
75000
3000
這還不是你唯一能找到的地方
01:33
The EPA estimates, in the United States,
32
78000
2000
美國環境保護局估計，
01:35
by volume, this material occupies 25 percent of our landfills.
33
80000
3000
在美國，塑膠材料佔了 25% 的土地面積
01:39
Even worse is when it finds its way into our natural environment --
34
84000
3000
更糟的是，它們也出現於我們的自然環境中 -
01:42
on the side of the road or next to a river.
35
87000
2000
在路旁或在河邊
01:44
If it's not picked up by a human, like me and you,
36
89000
3000
它如果不被人撿起，比如你我
01:47
it'll stay there for thousands and thousands of years.
37
92000
2000
它就會在那裡待上千千萬萬年
01:49
Perhaps even worse
38
94000
2000
甚至，更糟的是
01:51
is when it finds its way into our oceans, like in the great plastic gyre,
39
96000
3000
它出現於我們的海洋中，比如太平洋環流區的龐大塑膠漩渦
01:54
where these materials are being mechanically broken
40
99000
2000
在那，這些材料破碎成
01:56
into smaller and smaller bits,
41
101000
2000
一片一片小塊
01:58
but they're not really going away.
42
103000
2000
但它們不是真正消失
02:00
They're not biologically compatible.
43
105000
2000
它們無法生物分解
02:02
They're basically fouling up
44
107000
2000
它們基本上加速了
02:04
Earth's respiratory and circulatory systems.
45
109000
2000
地球的呼吸循環系統
02:06
And because these materials are so prolific,
46
111000
3000
另外，由於這些材料太大量了
02:09
because they're found in so many places,
47
114000
2000
由於它們覆蓋了太廣泛的地方
02:11
there's one other place you'll find this material, styrene,
48
116000
3000
你可以在一個地方發現這材料，苯乙烯
02:14
which is made from benzene, a known carcinogen.
49
119000
2000
由石油醚所構成，一種致癌物質
02:16
You'll find it inside of you.
50
121000
3000
你會發現它也會出現於你體內
02:19
So, for all these reasons,
51
124000
2000
基於這些原因
02:21
I think we need better materials,
52
126000
2000
我想我們需要更好的材料
02:23
and there are three key principles we can use to guide these materials.
53
128000
3000
我們可以依據三種原則使用這些材料
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
現今我們使用單一原料: 石油
02:32
to heat our homes, power our cars
56
137000
2000
以石油作為屋內暖氣來源、車用燃料、
02:34
and make most of the materials you see around you.
57
139000
3000
並且使用絕大多數的材料做成你周遭的物品
02:37
We recognize this is a finite resource,
58
142000
2000
我們認識到這是一種有限的資源
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
而且每一次當你拿到一個包裝，
02:42
every time you get a package.
60
147000
2000
就是把1.5公升的汽油丟到垃圾桶裡，這實在是一件很瘋的事
02:44
Second of all, we should really strive to use far less energy
61
149000
2000
第二，我們實在應該盡可能地大量減少使用能源
02:46
in creating these materials.
62
151000
2000
在製造這些材料上
02:48
I say far less, because 10 percent isn't going to cut it.
63
153000
3000
我說大量減少，因為 10% 是沒什麼作用的
02:51
We should be talking about half, a quarter,
64
156000
2000
我們應該討論是否降低一半、四分之一、
02:53
one-tenth the energy content.
65
158000
3000
至十分之一的能源含量
02:56
And lastly, and I think perhaps most importantly,
66
161000
3000
最後，我想這可能是最重要的
02:59
we should be creating materials
67
164000
2000
我們應該創造一種材料
03:01
that fit into what I call nature's recycling system.
68
166000
3000
一種可以融入自然回收系統的材料
03:04
This recycling system has been in place for the last billion years.
69
169000
3000
這個自然回收系統已存在了幾十億年
03:07
I fit into it, you fit into it,
70
172000
2000
我適應，你也適應
03:09
and a hundred years tops, my body can return to the Earth with no preprocessing.
71
174000
3000
一百年來，我的身體無須任何前置作業即可回歸地球
03:12
Yet that packaging I got in the mail yesterday
72
177000
2000
然而，我昨天拿到的郵件包裹
03:14
is going to last for thousands of years.
73
179000
2000
卻會存留上千年
03:16
This is crazy.
74
181000
2000
這太瘋狂了
03:18
But nature provides us with a really good model here.
75
183000
3000
但自然在這裡提供我們一個相當棒的模型
03:21
When a tree's done using its leaves --
76
186000
2000
當一棵樹用完它的葉子後 --
03:23
its solar collectors, these amazing molecular photon capturing devices --
77
188000
3000
它的太陽能集熱器，這些了不起的分子光子捕捉裝置 --
03:26
at the end of a season,
78
191000
2000
在季節終了的時候
03:28
it doesn't pack them up, take them to the leaf reprocessing center
79
193000
3000
並不是把它們包起來，丟到樹葉處理中心去
03:31
and have them melted down to form new leaves.
80
196000
2000
讓它們溶化解體，形成新葉
03:33
It just drops them, the shortest distance possible,
81
198000
3000
而就只是使樹葉落地，以最短的距離
03:36
to the forest floor,
82
201000
2000
掉落森林地面
03:38
where they're actually upcycled into next year's topsoil.
83
203000
2000
在那，它們實際上循環再造了下一年的表土
03:40
And this gets us back to the mushrooms.
84
205000
3000
這帶我們回到了蘑菇
03:44
Because in nature,
85
209000
2000
因為在大自然中
03:46
mushrooms are the recycling system.
86
211000
2000
蘑菇就是回收系統
03:48
And what we've discovered
87
213000
2000
我們所發現的是
03:50
is, by using a part of the mushroom you've probably never seen --
88
215000
2000
藉由一部份你可能從未見過的蘑菇 --
03:52
analogous to its root structure; it's called mycelium --
89
217000
3000
類似它的根結構。它被稱作菌絲體 --
03:55
we can actually grow materials
90
220000
2000
事實上，我們可以和許多相同傳統屬性的合成纖維
03:57
with many of the same properties of conventional synthetics.
91
222000
3000
一起長出材料來
04:00
Now, mycelium is an amazing material,
92
225000
2000
菌絲是一種異乎尋常的材料
04:02
because it's a self-assembling material.
93
227000
2000
因為它是一種可以自行組合的材料
04:04
It actually takes things we would consider waste --
94
229000
2000
事實上，我們可以考慮一些廢棄材料
04:06
things like seed husks or woody biomass --
95
231000
3000
比如種子外皮或木質生物質
04:09
and can transform them into a chitinous polymer,
96
234000
2000
把轉化成它們成幾丁質聚合物
04:11
which you can form into almost any shape.
97
236000
2000
你可以把它們轉化為任何形態
04:13
In our process,
98
238000
2000
在我們的過程中
04:15
we basically use it as a glue.
99
240000
2000
基本上，我們把它當成膠水
04:17
And by using mycelium as a glue,
100
242000
2000
利用菌絲體作為粘著劑
04:19
you can mold things just like you do in the plastic industry,
101
244000
3000
你可以塑造出你想要的東西，就像在塑膠產業裡
04:22
and you can create materials with many different properties,
102
247000
3000
你可以做出許多不同屬性的材料
04:25
materials that are insulating, fire-resistant,
103
250000
3000
絕緣的、耐火的、
04:28
moisture-resistant, vapor-resistant --
104
253000
3000
耐潮濕、耐水氣的、
04:31
materials that can absorb impacts, that can absorb acoustical impacts.
105
256000
3000
可以吸收聲響的材料
04:34
But these materials are grown from agricultural byproducts,
106
259000
3000
但是這些材料是從農作物生長出來的副產品
04:37
not petroleum.
107
262000
2000
不是石油
04:39
And because they're made of natural materials,
108
264000
3000
此外，由於它們是由自然物質所構成
04:42
they are 100 percent compostable
109
267000
2000
它們可以 100% 分解於
04:44
in you own backyard.
110
269000
2000
你家後院
04:47
So I'd like to share with you the four basic steps
111
272000
2000
我想和你們分享四個
04:49
required to make these materials.
112
274000
2000
製作這些材料的基礎步驟
04:51
The first is selecting a feedstock,
113
276000
2000
首先是選擇原料
04:53
preferably something that's regional, that's in your area, right --
114
278000
2000
最好是地方性的材料，在你周遭附近的材料 --
04:55
local manufacturing.
115
280000
2000
本地製造
04:57
The next is actually taking this feedstock and putting in a tool,
116
282000
3000
接著是把這些材料置於工具中
05:00
physically filling an enclosure, a mold,
117
285000
2000
完全地塞進一個
05:02
in whatever shape you want to get.
118
287000
2000
你想要的形狀的模具裡
05:04
Then you actually grow the mycelium through these particles,
119
289000
3000
接著，你使菌絲體成長，通過這些顆粒
05:07
and that's where the magic happens,
120
292000
2000
在這兒，魔法開始發生了
05:09
because the organism is doing the work in this process,
121
294000
2000
因為在這個過程中，是有機物質在運作著
05:11
not the equipment.
122
296000
2000
而不是設備
05:13
The final step is, of course, the product,
123
298000
2000
最後一個步驟，當然是產品
05:15
whether it's a packaging material, a table top, or building block.
124
300000
3000
無論它是包裝材料、書桌、或建築磚頭
05:18
Our vision is local manufacturing,
125
303000
2000
我們的眼光是本地製造
05:20
like the local food movement, for production.
126
305000
2000
就如同本地食材運動，而這是製造業方面的
05:22
So we've created formulations for all around the world
127
307000
2000
我們為全世界開發了
05:24
using regional byproducts.
128
309000
2000
使用在地農作副產品的方程式
05:26
If you're in China, you might use a rice husk
129
311000
3000
如果你在中國，你可能會使用稻殼
05:29
or a cottonseed hull.
130
314000
2000
或棉籽殼
05:31
If you're in Northern Europe or North America,
131
316000
2000
如果你在北歐或北美
05:33
you can use things like buckwheat husks or oat hulls.
132
318000
3000
你可用蕎麥皮或燕麥殼這些東西
05:37
We then process these husks with some basic equipment.
133
322000
3000
然後，我們以一些基本設備理處理這些稻殼
05:40
And I want to share with you a quick video from our facility
134
325000
2000
我想與你們快速分享一段關於我們設備的影片
05:42
that gives you a sense of how this looks at scale.
135
327000
3000
可以瞭解一下它的規模
05:45
So what you're seeing here is actually cotton hulls from Texas, in this case.
136
330000
3000
所以你們在這裡看到的，事實上是來自德州的棉殼
05:48
It's a waste product.
137
333000
2000
它是廢棄產品
05:50
And what they're doing in our equipment
138
335000
2000
他們在機具裡做的
05:52
is going through a continuous system,
139
337000
2000
是一個持續的系統
05:54
which cleans, cooks, cools
140
339000
3000
可以潔淨、調理、冷卻、
05:57
and pasteurizes these materials,
141
342000
2000
加熱殺菌這些原料
05:59
while also continuously inoculating them with our mycelium.
142
344000
3000
同時他們還不斷與我們的菌絲接種
06:02
This gives us a continuous stream of material
143
347000
2000
這給我們一個連續的材料源
06:04
that we can put into almost any shape,
144
349000
2000
使我們得以做出任何形狀
06:06
though today we're making corner blocks.
145
351000
2000
雖然今天我們正做著角塊
06:08
And it's when this lid goes on the part,
146
353000
2000
當這部份的蓋子掀開後
06:10
that the magic really starts.
147
355000
3000
魔法便開始了
06:13
Because the manufacturing process is our organism.
148
358000
3000
因為製造過程是我們的有機生物
06:16
It'll actually begin to digest these wastes
149
361000
2000
它事實上開始消化這些廢棄物
06:18
and, over the next five days,
150
363000
2000
而且，在接下來的五天
06:20
assemble them into biocomposites.
151
365000
3000
會把它們組織成生物複合材料
06:23
Our entire facility
152
368000
2000
我們的全部設備
06:25
is comprised of thousands and thousands and thousands of these tools
153
370000
3000
都是由這些上千的工具所組成
06:28
sitting indoors in the dark, quietly self-assembling materials --
154
373000
3000
待在黑暗之中，靜靜地自行組合材料
06:31
and everything from building materials
155
376000
2000
所有來自建材的東西
06:33
to, in this case,
156
378000
2000
在這個案例中
06:35
a packaging corner block.
157
380000
2000
是一個一包裝角塊
06:37
So I've said a number of times that we grow materials.
158
382000
3000
所以我已說了許多次，我們種出材料
06:40
And it's kind of hard to picture how that happens.
159
385000
2000
要描述這是如何發生的多少有點難度
06:42
So my team has taken five days-worth of growth,
160
387000
2000
於是我的團隊收取五天的成長
06:44
a typical growth cycle for us,
161
389000
2000
一個典型的成長循環
06:46
and condensed it into a 15-second time lapse.
162
391000
3000
把它濃縮為十五秒的間隔攝影
06:49
And I want you to really watch closely
163
394000
2000
我們想要更清楚地觀看
06:51
these little white dots on the screen,
164
396000
2000
這些在螢幕前的細小點點
06:53
because, over the five-day period,
165
398000
2000
因為，五天的時間裡
06:55
what they do is extend out and through this material,
166
400000
3000
他們所做的是延長這種材料，
06:58
using the energy that's contained in these seed husks
167
403000
2000
並且使用那些蘊藏在種子殼中的能源
07:00
to build this chitinous polymer matrix.
168
405000
2000
建造出這種幾丁質的聚合物
07:02
This matrix self-assembles,
169
407000
2000
這個混合物會自行組合
07:04
growing through and around the particles,
170
409000
2000
在粒子的周圍生長
07:06
making millions and millions of tiny fibers.
171
411000
3000
製造出好幾百萬的微小纖維
07:09
And what parts of the seed husk we don't digest,
172
414000
3000
而關於那些我們無法消化的種子殼，
07:12
actually become part of the final, physical composite.
173
417000
3000
實際上成了最終物理複合材料的一部份
07:15
So in front of your eyes, this part just self-assembled.
174
420000
2000
因此現在各位眼前的，是自行組合的一部份
07:17
It actually takes a little longer. It takes five days.
175
422000
3000
事實上會花上更長的時間，它需要五天
07:20
But it's much faster than conventional farming.
176
425000
3000
但是卻比傳統的耕種來得迅速許多
07:23
The last step, of course, is application.
177
428000
2000
最後一個步驟，當然是應用的部份了
07:25
In this case, we've grown a corner block.
178
430000
2000
在這個案例中，我們種植一個角塊
07:27
A major Fortune 500 furniture maker
179
432000
3000
財經雜誌全球500大企業中一間家具製造商
07:30
uses these corner blocks to protect their tables in shipment.
180
435000
3000
用這些角塊保護在裝運過程中的桌子
07:33
They used to use a plastic packaging buffer,
181
438000
2000
他們以前習慣使用塑膠包裝
07:35
but we were able to give them the exact same physical performance
182
440000
3000
但我們可以用我們長出來的材料
07:38
with our grown material.
183
443000
2000
給予他們相同的物理性能
07:40
Best of all, when it gets to the customer,
184
445000
3000
最重要的是，當它送達的客戶手裡時
07:43
it's not trash.
185
448000
2000
它不是垃圾
07:45
They can actually put this in their natural ecosystem without any processing,
186
450000
2000
事實上，他們可以把這放到自然生態系統裡，無須任何處置
07:47
and it's going to improve the local soil.
187
452000
2000
而且還可以增進當地的土壤效益
07:49
So, why mycelium?
188
454000
2000
那麼，為什麼是菌絲體呢?
07:51
The first reason is local open feedstocks.
189
456000
2000
第一個原因，它是本地的開放原料
07:53
You want to be able to do this anywhere in the world
190
458000
2000
你要可以在全世界各地製造
07:55
and not worry about peak rice hull or peak cottonseed hulls,
191
460000
2000
而不必擔心稻殼或棉籽的高價
07:57
because you have multiple choices.
192
462000
2000
因為你有多樣的選擇
07:59
The next is self-assembly,
193
464000
2000
接著是自行組合
08:01
because the organism is actually doing most of the work in this process.
194
466000
3000
因為實際上，有機物在這一過程中做了絕大部份的工作
08:04
You don't need a lot of equipment to set up a production facility.
195
469000
3000
你不需要裝設許多機具作為生產設備
08:07
So you can have lots of small facilities
196
472000
2000
所以你可以擁有很多小設施
08:09
spread all across the world.
197
474000
2000
散播到世界各地
08:11
Biological yield is really important.
198
476000
2000
生物產量是非常重要的
08:13
And because 100 percent of what we put in the tool become the final product,
199
478000
3000
而且，我們100%的投入都成為成為最終產品
08:16
even the parts that aren't digested
200
481000
2000
即使那些未被消化的部分
08:18
become part of the structure,
201
483000
2000
也成為結構的一部份
08:20
we're getting incredible yield rates.
202
485000
2000
我們得到驚人的收益率
08:22
Natural polymers, well ... I think that's what's most important,
203
487000
3000
天然聚合物，我認為這是最重要的
08:25
because these polymers have been tried and tested
204
490000
2000
因為這些聚合物
08:27
in our ecosystem for the last billion years,
205
492000
2000
已在我們的生態系統中經歷了億萬年的考驗
08:29
in everything from mushrooms to crustaceans.
206
494000
3000
無論是從蘑菇到甲殼類動物等任何東西
08:32
They're not going to clog up Earth's ecosystems. They work great.
207
497000
3000
它們不會堵塞地球的生態系統，它們一直做得很好
08:35
And while, today,
208
500000
2000
而今天
08:37
we can practically guarantee that yesterday's packaging
209
502000
2000
我們實際上可以保證，昨天的包裝
08:39
is going to be here in 10,000 years,
210
504000
2000
會留在這裡一萬年
08:41
what I want to guarantee
211
506000
2000
我想要保證的是
08:43
is that in 10,000 years,
212
508000
2000
在接下來的一萬年
08:45
our descendants, our children's children,
213
510000
2000
我們的子孫
08:47
will be living happily and in harmony
214
512000
3000
將會幸福和樂地
08:50
with a healthy Earth.
215
515000
2000
住在健康的地球
08:52
And I think that can be some really good news.
216
517000
2000
而我想那應該是個真正的好消息
08:54
Thank you.
217
519000
2000
謝謝
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.
