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.

That doesn't mean I didn't care about the plastic. First of all, I chose the smallest camera I could find. Check it out. This thing is the size of a credit card and will easily fit in my pocket. (I took this photo with my cell phone and had to doctor it in Photoshop to make it as sharp as it is.)

Remember this picture of my plastic waste from Week 35? Remember
Oh joy! I've been waiting for the week when my plastic waste would finally fit easily in my own two hands, and this was that week. Don't get me wrong. We still have plastic in this house that we're using up, and the tally will go up again. But it's nice to savor small victories.

After using a screwdriver to take it apart (which I'd already done in the end of December), you need an ohmmeter or multimeter to test the circuitry. As I was attempting to write this post last night, I realized I didn't know how to explain how my dad used his multimeter to test the wires. So I asked him to send me an explanation, and this is what he wrote:
By looking really closely, we were able to decipher the specs printed on the outside of the old fuse: 10A, 250V, 113°C. My dad said a new thermal fuse needed to have at least those ratings, but could be rated for a slightly higher temperature as well, if we couldn't find an exact replacement. Fortunately, having worked as an electronics technician for the phone company in Honolulu back in the 60's, he knew exactly where to go to get a new one.
Dad used a soldering iron to make a strong connection between the leads on the thermal fuse and the connectors on the appliance. Michael and I don't own our own soldering iron, but I checked the offerings of the
And it worked! The hardest part for me was remembering how to put everything back together again. I'd taken the dryer apart in the end of December and didn't write any notes about what went where. So it was a puzzle for me, but finally, I got it together and can use it again. (That's me doing the head upside-down hair drying thing I've been doing since Junior High.) Now I can return my friend Mark's dryer that he lent me until mine was fixed.
Back in August, when Fake Plastic Fish was less than two months old, and I'd only recently become aware of my plastic consumption, my sandal broke. In fact, the elastic strap had become so worn, I had a feeling it might break that very day as I left the house and packed an extra pair of flip flops just in case. Sure enough, it snapped as I was walking down the street. The old me would have automatically tossed them out and bought a new pair. But these were some of my most comfortable shoes, and I didn't want to waste them, plastic or not, so I found a
Since then, I've had a few more opportunities to fix things instead of throwing them away. For example, for months, my computer mouse was operating eratically, refusing to move the pointer where I wanted it to. The old me would have junked it and bought a new one, but this was the new me. Determined to make it work again instead of getting a new hunk of plastic, I found an article on eHow.com called
Recently, the wire on my favorite cheese slicer snapped. I've had this things for many years, and it's served me well. Surely I could find a replacement wire for it. This, however, turned out to be a more difficult task than I expected. I visited multiple hardware stores with my cheese slicer attempting to find the right kind of wire. They all seemed to have something called "galvanized steel," which apparently is not rust-proof or strong enough. I'm glad I actually asked for advice instead of just buying the first wire that looked similar to the one that broke.
Another energy-saving measure that I really like is an item that's, ironically, made of plastic. Its the
This weekend, I had a conversation with my dad about what to do with certain possessions if he rented out their condo in Hawaii. "I'd have to store a lot of books," he said. And it got me realizing that one of the best ways to reduce our consumption, plastic and otherwise, is through borrowing and sharing items that we don't need access to on a regular basis.
