No Technology is Truly Green: A guest post from Alyssa J. Pasquale
Before you invest in that new "green" computer or purchase those fun solar deck lights, read this insider's perspective from Fake Plastic Fish reader Alyssa J. Pasquale and consider whether buying new technology is ever truly green. If you have an idea for a guest post, please email me at beth[at]fakeplasticfish[dot]com and let me know. I'd love to feature more of your ideas here!
I would first like to thank Beth for allowing me to write this guest post. My name is Alyssa and I am a PhD candidate at a very large university in Boston. I work in electrical engineering and have a focus on photonic devices. These are generally nanometer-scale devices that use light to do something cool. Some people in my department work on biological sensors, some on solar cells, some on lasers, and some on LEDs.
I’ve been doing research for a long time (I started as an undergrad) and one thing that’s prevalent in my work is lots and lots of waste. As I told Beth, I find it awfully ironic that the technology that is being hailed by many as able to save the world is such a large producer of toxic waste. And people who don’t work in R&D or in high tech industry might not be aware of what goes into your LED flashlight or the laser that does your eye surgery.
Being a PhD candidate can be disillusioning in many ways. Not only are you constantly surrounded by many of extremely intelligent people who know more than you, but you learn about all of the limitations of everything. LEDs will always consume power. Solar cells will never be 100% efficient. Lasers will never be perfectly coherent. In other words, nothing comes for free.
My work brings me into a class 1000 clean room quite often. (A class 1000 clean room means that there are 1000 particles of dust allowed in any cubic foot of airspace. It doesn’t necessarily mean that it’s clean!) This is probably the area of my research that creates the most waste, and much of it is plastic. What follows is a list of the plastic things that I interact with in the clean room, as well as whether or not it’s reusable, disposable, or can be reused.
(Shown in photo: two bouffant caps, four nitrile gloves, a few strips of Parafilm, one small wiper, one petri dish with lid, one gel pack sample holder.)
REUSABLE (Routinely reused.)
o Gowns, booties & hoods – It is mandatory to wear a gown when you enter a clean room. It is not to protect you from chemicals; it is to protect the clean room from all of your skin cells! The ones in my lab are made of 99% polyester and 1% carbon. (I don’t know why they have carbon in them.) These are washed once a week and are returned individually shrink-wrapped in plastic disposable baggies (to keep dust out during transit, presumably).
o Goggles – These are likely made from polycarbonate.
o Face shield – Probably made from polycarbonate, these are important to wear when working with dangerous chemicals. The last thing you want to get is acid splashing on your face. They’re also a joy to wear when you have on glasses and goggles and your glasses start sliding down and you can’t touch your face. (Not.)
o PTFE tweezers – When working with acids and bases, you need an inert material to use as a tweezer because metal will corrode. PTFE is polytetrafluroethylene, better known as Teflon.
o Beakers – As I said before, some chemicals etch glass, so if you have to pour them out it has to be into a plastic jar.
MIGHT BE REUSED
o Sample holders – These can be simple like plastic petri dishes or more complicated gel packs that have a layer of sticky gel to keep samples from sliding around.
o Protective equipment covers – These are like the film that comes over your cell phone screens. I’m not sure what exactly it’s made of but I’d be shocked if it’s not plastic. These are to protect equipment from any chemicals that may be on our nitrile gloves.
o Heavy duty chemical gloves – These are for when you work with heavy duty chemicals. The plastic it’s made of depends on which you buy. Some can be PVC, Neoprene or heavy duty latex. Nitrile gloves are thin and easily eaten by acids. Heavy duty gloves can generally be reused until they start to break down after too much chemical exposure.
o Chemical jugs – Most chemicals we buy are in plastic jugs, some in glass. Some chemicals (such as HF) absolutely have to be in plastic because they etch glass. There are only two chemicals (out of many) that I use in glass jars, most come in plastic. We reuse them as waste jars but I honestly have no idea what happens to them after that.
DISPOSABLE
o Pipettes & wrappers
o Clean room wipers – These are pieces of “paper” that we use to wipe up chemicals, or write notes about things as we’re working. I was astonished to find out that they are not really paper, but a mix of 55% cellulose and 45% polyester. They are not supposed to release any fibers (dust) into the air, and cannot be easily ripped (if you do manage to rip one, no fibers are released, unlike what happens when you rip paper).
o Bouffant caps – Made from 100% polypropylene, these protect the clean room from hair. (They are like hair nets that food service workers use.)
o Nitrile gloves – The clean room uses nitrile gloves. Other facilities use latex gloves but I’m not sure if they are natural or synthetic. Nitrile gloves are a synthetic rubber copolymer.
o Parafilm – This is a thermoplastic used to seal jars and bottles.
o Tape – We use a lot of plastic tape in the lab. Vacuum tape and double sided tape are very popular.
That list just encompasses the plastic that is generated due to clean room work. It doesn’t consider any of the other waste, such as the HUGE amounts of chemical waste. (In one day I can easily use acetone, methanol, isopropanol, polymer resins, methyl isobutyl ketone, tetramethyl ammonium hydroxide, hydrochloric acid, hydrogen peroxide, potassium iodide, hydrofluoric acid, and a lot of de-ionized water. Not to mention the gases – sulfur hexafluoride, methane, nitrogen, oxygen, argon, tri-fluoromethane, etc. etc.)
There is also a lot of plastic that comes with the life of a grad student. We’re constantly buying supplies, and most of the time they come in plastic. Chemicals especially need a lot of isolation in shipping and will generally have many layers of foam, plastic, vermiculite, and lots of warning labels to keep upright. Computers come with plastic towers (and we use a lot of computers).
Seminars and other such meetings are held an awful lot in my building, and there is also plastic waste related with this. The department provides bottled water and sodas at some events (fortunately, some events have reusable beverage urns). For some strange reason the lemons for the tea are always wrapped in plastic wrap. The food is put on plastic trays (which I assume are reused). Crackers are sometimes served and they come in plastic sleeves.
Not to mention the lifestyle of being a grad student. While I personally use my flexible hours to ensure that I have enough time to home cook all of my meals (and I always bring in lunch in a glass container with a plastic – oops – lid), many grad students opt for take-out. There’s a Subway that’s not far from my building, and many students come in between noon and one with a plastic bag holding a giant sandwich. Lots of students consume lots of bottled water. I know of a few students with Nalgene bottles or reusable coffee mugs. I have a SIGG bottle. One of my office-mates actually keeps a Brita filter on his desk. But most opt for bottled water even though we have perfectly good water fountains on every floor.
So next time you buy or read about a newly engineered “green” product – such as an LED lighting device – think about what went into it. While better than older alternatives, I wouldn’t call most technology “green” at all. Although it may sound hypocritical coming from an engineer, there’s a lot to be said for old-fashioned technology.

Moore is not much taller than I, but his presence is captivating and the force of his conviction, palpable. Wearing a necklace made of plastic found out in the North Pacific Gyre, he is a man who has looked into the abyss, not once but repeatedly, and returned to warn us about it. His eyes twinkle, but they also look deeply tired. He has been trying to get us to wake up to the the damage we're doing to our precious planet for over ten years, and the world is just now starting to listen.



This just in: Oregon plastics recycler,
The ferocious flu that hit me several weeks ago resulted in quite a few trips to Kaiser Permanente. During one of those visits, I noticed something in the public restroom I'd never seen there before: a green bin and green liner... telltale signs of composting afoot. I moved in to take a closer look. Sure enough... compostable liner and a sign above the bin instructing users to deposit paper towel waste there.
Sick as I was, I had my camera with me and the presence of mind to snap a few shots, while curious restroom users stared. I forgot about this green moment in Kaiser until reading the

The following is a letter that I am sending off tonight to the Santa Sabina Retreat Center, where I spent this past weekend, and about 12 previous weekends since 2000, sitting in silence. I share this letter here only to demonstrate that we can have a voice, write our letters and make our calls, and do it all in a spirit of sharing and love rather than confrontation or hostility. I love Santa Sabina. I truly do. Here's the letter:

The reusable bag is made of Dupont Tyvek, the type of plastic that many large postal envelopes are made from. The cover of the book states, "This book and the reusable Tyvek bag are 100% recyclable!" What you don't realize until you read the fine print (if you read the fine print) is that Tyvek is only recyclable by mailing it back to Dupont. I devoted

Anyway, reading these two books lead me to think about my own relationship with certain non-human beings and the ways that I care for them and also exploit their cuteness for my own personal gain. Right here on this blog! Maybe that's just part of human nature. To marvel at how animals of completely different species can bond with one another without the slightest clue what it's actually like to be that other creature. We have to be so careful, don't we?





By now, everyone has heard about the terrible oil spill in the San Francisco Bay last week. Friday, I stopped at the wharf on my way to the Green Festival, to see for myself. The smell was terrible. Like walking into a chemical factory, except it was outside! Oil floated on top of the water instead of ducks. And the boat that hit the Bay Bridge was still anchored out there like a bad dog tied to a stake. Here are a few of the photos I took on Friday:







In the meantime, continuing with the global warming/energy conservation theme this week, and needing to provide a little Halloween scare, I thought I'd share some information I just discovered.
Another energy-saving measure that I really like is an item that's, ironically, made of plastic. Its the
Nearly every "green" blog and web site these days focuses on global warming. And it seems like many of them focus on it to the exclusion of all other environmental issues. In fact, a few days ago, I read something that made me feel really sad. Alan Morton wrote in an

While I appreciated the thought that went into presenting these speakers to us, I was more struck by the irony of what I saw when I first stepped through the auditorium door. Knowing it was dinnertime, the organizers had been kind enough to provide snacks: individual plastic-wrapped granola bars! Several speakers mentioned that plastic wrappers are some of the worst trash entering the bay. Did no one notice the plastic wrappers just a few feet away?
