工安意外不斷 台塑到底出啥問題？
來賓：
台灣綠黨召集人 潘翰聲
作家 張曉風
台大職業醫學與工業衛生所副教授 吳焜裕
CALL-OUT 嘉義縣環保局長 沈弘文(1900~1935)
【工安意外不斷 台塑到底出啥問題？】
南亞嘉義二廠發生工安大火，延燒時將近十七個小時，終於在今天清晨撲滅。
台塑集團總裁王文淵今天也親自南下善後，並對嘉義縣民鞠躬道歉，表示南亞公司會負全責，也答應縣長張花冠的要求，在一半個月內完成，台塑在嘉義境內所有工廠的總體檢。
南亞塑膠二廠經過十幾個小時的大火，不僅造成當地居民恐慌，嘉義縣府也陸續接到民眾受害狀況，因此也決定成立申訴管道。到底有沒有毒？地方政府掌握情況？對人體有無傷害？對農作物及畜牧有無傷害？
而這場嘉義有史以來最大的火災，從白天燒到黑夜，南亞公司居然從頭到尾，都沒有打電話到消防局報案，所有的電話都是民眾打的，有沒有延遲通報的疏失，廠方如何解釋？
一向以管理嚴格著名的台塑企業，其中位在雲林的六輕，卻在今年發生了兩次爆炸，七月的大火更引來村民封廠圍街、縣長蘇治芬下跪的抗議場面。外界紛紛質疑，接連出事、問題頻傳，是因為王永慶死了？台塑螺絲鬆了？或是這個企業本來就是這樣？一切成本數據化，一切成本最低化？
惡名昭彰！為何之前都沒有媒體報導？地方政府與中央政府為何如此無力？
Eben Bayer: Are mushrooms the new plastic?
About this talk
Product designer Eben Bayer reveals his recipe for a new, fungus-based packaging material that protects fragile stuff like furniture, plasma screens -- and the environment.
Summary
Mycelium (plural mycelia) is the vegetative part of a fungus, consisting of a mass of branching, thread-like hyphae. The mass of hyphae is sometimes called shiro, especially within the fairy ring fungi. Fungal colonies composed of mycelia are found in soil and on or in many other substrates. Typically a single spore germinates into a monokaryotic mycelium which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or it may be extensive:
Is this the largest organism in the world? This 2,400-acre (9.7 km2) site in eastern Oregon had a contiguous growth of mycelium before logging roads cut through it. Estimated at 1,665 football fields in size and 2,200 years old, this one fungus has killed the forest above it several times over, and in so doing has built deeper soil layers that allow the growth of ever-larger stands of trees. Mushroom-forming forest fungi are unique in that their mycelial mats can achieve such massive proportions.
—Paul Stamets, Mycelium Running
It is through the mycelium that a fungus absorbs nutrients from its environment. It does this in a two stage process. Firstly the hyphae secrete enzymes onto the food source, which breaks down polymers into monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active transport.
Mycelium is vital in terrestrial and aquatic ecosystems for its role in the decomposition of plant material. It contributes to the organic fraction of soil and its growth releases carbon dioxide back into the atmosphere. The mycelium of mycorrhizal fungi increases the efficiency of water and nutrient absorption of most plants and confers resistance to some plant pathogens. Mycelium is an important food source for many soil invertebrates.
Sclerotia are compact or hard masses of mycelium.
So, I'd like to spend a few minutes with you folks today 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 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. Not like that. (Laughter) We're using mushrooms to create an entirely new class of materials, which perform a lot like plastics during their use, but are made from crop waste and are totally compostable at the end of their lives.
(Cheering)
But first, I need to talk to you about what I consider one of the most egregious offenders in the disposable plastics category. This is a material you all know is Styrofoam, but I like to think of it as toxic white stuff. 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 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. The EPA estimates, in the United States, by volume, this material occupies 25 percent of our landfills. Even worse is when it 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. They're not biologically 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 benzine, a known carcinogen. You'll find it inside of you.
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 feedstocks. Today, we use a single feedstock, petroleum, to heat our homes, 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. 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 going to cut it. We should be 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. Yet that packaging I got in the mail yesterday is going to last for thousands of years. 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 molecule 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. And this gets us back to the mushrooms. Because in nature, 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 grow materials with many of the same properties of conventional synthetics.
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 biomass -- and can transform them into a chitinous polymer, which you can form into almost any shape. In our process, we basically use it as a glue. 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, vapor-resistant -- materials that can absorb impacts, that can absorb acoustical impacts. But these materials are grown from agricultural byproducts, not petroleum. And because they're made of natural materials, they are 100 percent compostable in you own backyard.
So I'd like to share with you the four basic steps required to make these materials. The first is selecting a feedstock, preferably something that's regional, that's in your area, right -- local manufacturing. The next is actually taking this feedstock 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, because the 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 building block. Our vision is local manufacturing, like the local food movement, for production. So we've created formulations for all around the world using regional byproducts. 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 want to share with you a quick video from our facility that gives you a sense of how this looks at scale. So what you're seeing here is actually cotton hulls from Texas, in this case. It's a waste product. And what they're doing in our equipment is going through a continuous system, which cleans, cooks, cools and 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. Because the manufacturing process is our organism. It'll actually begin to digest these 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.
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 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. 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 digest, actually become part of the final, physical composite. So in front of your eyes, this part just self-assembled. It actually takes a little longer. It takes five days. 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 maker 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. Best of all, when it gets to the customer, it's not trash. They can actually put this in their natural ecosystem without any processing, and it's going to improve the local soil.
So, why mycelium? The first reason is local open feedstocks. You want to 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. 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 spread all across the world. Biological yield is really important. And because 100 percent of what we put in the tool become the final product, even the parts that aren't digested become part of the structure, we're getting incredible yield rates.
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 ecosystems. They work great. And while, today, we can practically guarantee that yesterday's packaging is going to be here in 10,000 years, what I want to guarantee is that in 10,000 years, our descendants, our children's children, will be living happily and in harmony with a healthy Earth. And I think that can be some really good news.
Thank you.

Mycobond is a mycological bio-composite that can be used in a wide variety of applications. Instead of conventional manufacturing processes, Mycobond uses mycelium—which is essentially the root system of a mushroom—to transform loose aggregates into strong composites. This process can be varied by using different species of fungus and mixtures of aggregates in order to make a composite with an optimal density, strength, appearance, and performance for the specific application.
Additionally, Mycobond represents a low-embodied-energy manufacturing process as the material self assembles at room temperature and pressure in the dark. Furthermore, Mycobond upcycles resources like rice hulls, cotton burrs, and buckwheat hulls that are otherwise thrown away, transforming them into valuable products, including rigid board insulation and protective packaging buffers.

Mixing Mind and Metaphor
About this talk
Aphorism enthusiast and author James Geary waxes on a fascinating fixture of human language: the metaphor. Friend of scribes from Aristotle to Elvis, metaphor can subtly influence the decisions we make, Geary says.
Mixing Mind and Metaphor - Talk by James Geary, given at TED Global 2009 July. Prezi was co-created by James and Adam Somlai-Fischer.See the talk at http://www.ted.com/talks/james_geary_metaphorically_speaking.html
Metaphor lives a secret life all around us. We utter about six metaphors a minute. Metaphorical thinking is essential to how we understand ourselves, and others, how we communicate, learn, discover and invent. But metaphor is a way of thought before it is a way with words.
Now, to assist me in explaining this, I've enlisted the help of one of our greatest philosophers, the reigning king of the metaphorians, a man whose contributions to the field are so great that he himself has become a metaphor. I am, of course, referring to none other than Elvis Presley. (Laughter)
Now, "All Shook Up" is a great love song. It's also a great example of how whenever we deal with anything abstract ideas, emotions, feelings, concepts, thoughts, we inevitably resort to metaphor. In "All Shook Up," a touch is not a touch, but a chill. Lips are not lips, but volcanoes. She is not she, but a buttercup. And love is not love, but being all shook up.
In this, Elvis is following Aristotle's classic definition of metaphor as the process of giving the thing a name that belongs to something else. This is the mathematics of metaphor. And fortunately it's very simple. X equals Y. (Laughter) This formula works whereever metaphor is present.
Elvis uses it, but so does Shakespeare in this famous line from "Romeo and Juliet," Juliet is the sun. Now, here, Shakespeare gives the thing, Juliet, a name that belongs to something else, the sun. But whenever we give a thing a name that belongs to something else, we give it a whole network of analogies too. We mix and match what we know about the metaphor's source, in this case the sun, with what we know about its target, Juliet. And metaphor gives us a much more vivid understanding of Juliet than if Shakespeare had literally described what she looks like.
So, how do we make and understand metaphors? This might look familiar. The first step is pattern recognition. Look at this image. What do you see? Three wayward Pac Men, and three pointy brackets are actually present. What we see, however, are two overlapping triangles. Metaphor is not just the detection of patterns; it is the creation of patterns. Second step, conceptual synesthesia.
Now, synesthesia is the experience of a stimulus in once sense organ in another sense organ as well, such as colored hearing. People with colored hearing actually see colors when they hear the sounds of words or letters. We all have synesthetic abilities. This is the Bouba/Kiki test. What you have to do is identify which of these shapes is called Bouba, and which is called Kiki. (Laughter)
If you are like 98 percent of other people, you will identify the round, amoebiod shape as Bouba, and the sharp, spiky one as Kiki. Can we do a quick show of hands? Does that correspond? Okay, I think 99.9 would about cover it. Why do we do that? Because we instinctively find, or create, a pattern between the round shape, and the round sound of Bouba, and the spiky shape, and the spiky sound of Kiki.
And many of the metaphors we use everyday are synesthetic. Silence is sweet. Neckties are loud. Sexually attractive people are hot. Sexually unattractive people leave us cold. Metaphor creates a kind of conceptual synesthesia, in which we understand one concept in the context of another.
Third step is cognitive dissonance. This is the Stroop test. What you need to do here is identify as quickly as possible the color of the ink in which these words are printed. You can take the test now. If you're like most people, you will experience a moment of cognitive dissonance when the name of the color is printed in a differently colored ink. The test shows that we can not ignore the literal meaning of words even when the literal meaning gives the wrong answer.
Stroop tests have been done with metaphor as well. The participants had to identify, as quickly as possible, the literally false sentences. They took longer to reject metaphors as false than they did to reject literally false sentences. Why? Because we cannot ignore the metaphorical meaning of words either.
One of the sentences was, "Some jobs are jails." Now, unless you're a prison guard, the sentence "Some jobs are jails" is literally false. Sadly, it's metaphorically true. And the metaphorical truth interferes with our ability to identify it as literally false. Metaphor matters because it's around us every day, all the time. Metaphor matters because it creates expectations.
Pay careful attention the next time you read the financial news. Agent metaphors describe price movements as the deliberate action of a living thing, as in, "The NASDAQ climbed higher." Object metaphors describe price movements as non-living things, as in, "The Dow fell like a brick."
Researchers asked a group of people to read a clutch of market commentaries, and then predict the next day's price trend. Those exposed to agent metaphors had higher expectations that price trends would continue. And they had those expectations because agent metaphors imply the deliberate action of a living thing pursuing a goal. If, for example, house prices are routinely described as climbing and climbing, higher and higher, people might naturally assume that that rise is unstoppable. They may feel confident, say, in taking out mortgages they really can't afford. That's a hypothetical example of course. But this is how metaphor misleads.
Metaphor also matters because it influences decisions by activating analogies. A group of students was told that a small democratic country had been invaded and had asked the U.S. for help. And they had to make a decision. What should they do? Intervene, appeal to the U.N., or do nothing? They were each then given one of three descriptions of this hypothetical crisis. Each of which was designed to trigger a different historical analogy: World War II, Vietnam, and the third was historically neutral.
Those exposed to the World War II scenario made more interventionist recommendations than the others. Just as we can not ignore the literal meaning of words, we can not ignore the analogies that are triggered by metaphor. Metaphor matters because it opens the door to discovery. Whenever we solve a problem, or make a discovery, we compare what we know with what we don't know. And the only way to find out about the latter is to investigate the ways it might be like the former.
Einstein described his scientific method as combinatory play. He famously used thought experiments, which are essentially elaborate analogies, to come up with some of his greatest discoveries. By bringing together what we know and what we don't know through analogy, metaphorical thinking strikes the spark that ignites discovery.
Now metaphor is ubiquitous, yet it's hidden. But you just have to look at the words around you and you'll find it. Ralph Waldo Emerson described language as "fossil poetry." But before it was fossil poetry language was fossil metaphor. And these fossils still breathe.
Take the three most famous words in all of Western philosophy: "Cogito ergo sum." It is routinely translated as, "I think, therefore I am." But there is a better translation. The Latin word "cogito" is derived from the prefix "co," meaning "together," and the verb "agitare," meaning "to shake." So, the original meaning of "cogito" is to shake together. And the proper translation of "cogito ergo sum" is "I shake things up, therefore I am." (Laughter)
Metaphor shakes things up, giving us everything from Shakespeare to scientific discovery in the process. The mind is a plastic snow dome, the most beautiful, most interesting, and most itself, when, as Elvis put it, it's all shook up. And metaphor keeps the mind shaking, rattling and rolling, long after Elvis has left the building. Thank you very much. (Applause)
Aphorism enthusiast and author James Geary waxes on a fascinating fixture of human language: the metaphor. Friend of scribes from Aristotle to Elvis, metaphor can subtly influence the decisions we make, Geary says.
Mixing Mind and Metaphor - Talk by James Geary, given at TED Global 2009 July. Prezi was co-created by James and Adam Somlai-Fischer.See the talk at http://www.ted.com/talks/james_geary_metaphorically_speaking.html
Metaphor lives a secret life all around us. We utter about six metaphors a minute. Metaphorical thinking is essential to how we understand ourselves, and others, how we communicate, learn, discover and invent. But metaphor is a way of thought before it is a way with words.
Now, to assist me in explaining this, I've enlisted the help of one of our greatest philosophers, the reigning king of the metaphorians, a man whose contributions to the field are so great that he himself has become a metaphor. I am, of course, referring to none other than Elvis Presley. (Laughter)
Now, "All Shook Up" is a great love song. It's also a great example of how whenever we deal with anything abstract ideas, emotions, feelings, concepts, thoughts, we inevitably resort to metaphor. In "All Shook Up," a touch is not a touch, but a chill. Lips are not lips, but volcanoes. She is not she, but a buttercup. And love is not love, but being all shook up.
In this, Elvis is following Aristotle's classic definition of metaphor as the process of giving the thing a name that belongs to something else. This is the mathematics of metaphor. And fortunately it's very simple. X equals Y. (Laughter) This formula works whereever metaphor is present.
Elvis uses it, but so does Shakespeare in this famous line from "Romeo and Juliet," Juliet is the sun. Now, here, Shakespeare gives the thing, Juliet, a name that belongs to something else, the sun. But whenever we give a thing a name that belongs to something else, we give it a whole network of analogies too. We mix and match what we know about the metaphor's source, in this case the sun, with what we know about its target, Juliet. And metaphor gives us a much more vivid understanding of Juliet than if Shakespeare had literally described what she looks like.
So, how do we make and understand metaphors? This might look familiar. The first step is pattern recognition. Look at this image. What do you see? Three wayward Pac Men, and three pointy brackets are actually present. What we see, however, are two overlapping triangles. Metaphor is not just the detection of patterns; it is the creation of patterns. Second step, conceptual synesthesia.
Now, synesthesia is the experience of a stimulus in once sense organ in another sense organ as well, such as colored hearing. People with colored hearing actually see colors when they hear the sounds of words or letters. We all have synesthetic abilities. This is the Bouba/Kiki test. What you have to do is identify which of these shapes is called Bouba, and which is called Kiki. (Laughter)
If you are like 98 percent of other people, you will identify the round, amoebiod shape as Bouba, and the sharp, spiky one as Kiki. Can we do a quick show of hands? Does that correspond? Okay, I think 99.9 would about cover it. Why do we do that? Because we instinctively find, or create, a pattern between the round shape, and the round sound of Bouba, and the spiky shape, and the spiky sound of Kiki.
And many of the metaphors we use everyday are synesthetic. Silence is sweet. Neckties are loud. Sexually attractive people are hot. Sexually unattractive people leave us cold. Metaphor creates a kind of conceptual synesthesia, in which we understand one concept in the context of another.
Third step is cognitive dissonance. This is the Stroop test. What you need to do here is identify as quickly as possible the color of the ink in which these words are printed. You can take the test now. If you're like most people, you will experience a moment of cognitive dissonance when the name of the color is printed in a differently colored ink. The test shows that we can not ignore the literal meaning of words even when the literal meaning gives the wrong answer.
Stroop tests have been done with metaphor as well. The participants had to identify, as quickly as possible, the literally false sentences. They took longer to reject metaphors as false than they did to reject literally false sentences. Why? Because we cannot ignore the metaphorical meaning of words either.
One of the sentences was, "Some jobs are jails." Now, unless you're a prison guard, the sentence "Some jobs are jails" is literally false. Sadly, it's metaphorically true. And the metaphorical truth interferes with our ability to identify it as literally false. Metaphor matters because it's around us every day, all the time. Metaphor matters because it creates expectations.
Pay careful attention the next time you read the financial news. Agent metaphors describe price movements as the deliberate action of a living thing, as in, "The NASDAQ climbed higher." Object metaphors describe price movements as non-living things, as in, "The Dow fell like a brick."
Researchers asked a group of people to read a clutch of market commentaries, and then predict the next day's price trend. Those exposed to agent metaphors had higher expectations that price trends would continue. And they had those expectations because agent metaphors imply the deliberate action of a living thing pursuing a goal. If, for example, house prices are routinely described as climbing and climbing, higher and higher, people might naturally assume that that rise is unstoppable. They may feel confident, say, in taking out mortgages they really can't afford. That's a hypothetical example of course. But this is how metaphor misleads.
Metaphor also matters because it influences decisions by activating analogies. A group of students was told that a small democratic country had been invaded and had asked the U.S. for help. And they had to make a decision. What should they do? Intervene, appeal to the U.N., or do nothing? They were each then given one of three descriptions of this hypothetical crisis.
