Environmental Morality Debate: ADC is Landfilling. Exporting is Dumping. You're Throwing Away. Garbage!

1980s Moral/Environmental Superiority

"You threw your television away??  I reused it.  I sold mine at a yard sale, or donated it to a charity.

Yours went into a landfill where it will be blown in the wind and seep into the groundwater!"

1990s Moral/Environmental Superiority

"You threw your television and computer away??  I reused my computer, and the television was recycled back into a new television, the plastic, metal and glass reused.

Yours went into a landfill where it will be blown in the wind and seep into the groundwater!"

2000s Moral/Environmental Superiority 

"You threw your TV, PC and cell phone away??  I reused my cell phone.   The TV and computer were recycled back into new metals, plastic and glass products.

Yours went into a landfill where it will be blown in the wind and seep into the groundwater!  Or worse, got shipped to a country with poor people."

2010's  Moral/Environmental Superiority  

"You threw your TV, PC and cell phone away??  I sent mine to a shredding machine.   The metal and some of the plastic were recycled back into new metals and plastics.

The leaded glass from mine went on top of yours, as wind cover.  Like yours, it will be blown by the wind and seep into groundwater.

But mine will be on a layer on top of yours today.  Tomorrow, when the landfill reopens, another CRT will be dumped on top of my "yester-daily cover".  And another layer of shedded CRTs will be placed on that.  And so on..."

Environmental Moral superiority just ain't what it used to be.

In certified programs, almost nothing gets reused anymore.

This is "moral relativism" not across geographic boundaries, but across decades and their relative economies.

What does this "moral environmentalist standards evolution" tell us about Environmentalism?  Harken back to the Priestatollah Blog ("E-Waste Whiplash").  Beware moral fetishes attached to scientific environmental problems.   Environmental health studies, like human health and medicine, need to stay firmly in the science camp, and let's keep our ears, eyes, and minds open to scientific method, healthy reasoning.

CRT Glass Market Murder Mystery: Killing with Friendly Fire


"I have to say something." 

We have a really, really immature CRT glass recycling industry.  With a couple of exceptions like Dave Dlubak, who knows how to keep quiet after 3 generations of managing scrap glass, we have a lot of people who think that negative campaigning against each other is the way to put themselves ahead.

"There is a time to laugh and a time not to laugh, and this is not one of them."

Our "e-waste" recycling industry, in general, has made a mess out of "investigations" and "diligence" (or dis-lingence) of cullet end markets.  Having put the word "waste" in the title of our commodity, we were off to a bad start.  And it got worse.

We had a very, very low bar to meet, environmentally.  Provide leaded silicate in a way which is safer than virgin lead mining.  100 years of environmental science were behind the "hierarchy" of reuse, recycling and mining-for-disposal.  Stand at a mine like OK Tedi in Papua New Guinea, where cyanide tailings rush out of the rainforest, killing all the coral reefs.   Stand at a lead mine in Peru, or Kabwe Zambia (the most toxic place on earth).  All we had to do was take lead and silica which has already been mined, already been refined, and deliver it to replace the virgin raw material.  The worst recycling beats the best mining.

But greed for competitive advantages between recyclers has gotten in the way, and "inspection costs" are now perceived by the buyers to outweigh the financial and environmental advantages of CRT glass recycling.

2005:  I worked very, very hard in 2005 to open up the Samsung, Klang, Malaysia CRT furnace to secondary cullet.  That means recycled CRT glass.   We worked with one of the largest CRT contract assembly companies on the planet, who purchased $200M in new CRT tubes from Samsung Klang in 2003, to use their purchasing influence to open the door.

2008:  Someone in the USA, I won't say who, but in our industry, was upset that Samsung was taking "unwashed glass".  The Recycler had put in an investment to wash the phosphor. So they told a certain NGO in Washington to contact the Malaysia EPA about Samsung taking in unwashed glass to recycle it.

"Could you give us a statement please?"
"Yes. 'Chocolate makes one very thirsty.'"

Wonder and Doubt: Solved by Machines

Reading about how IBM's Watson computer is learning to make pastries on NYTimes.   If we had the right Bayesian statistics, the right DNA code (to predict likelihood of gene X "liking" taste Y), and the supercomputer to put them all together... theoretically you'd have a Utopia where everyone always got precisely what they ordered in life.  The right taste, the optimum number of calories.  Maybe Watson can even do Kosher...

Taking the hypothesis of ultra intelligence to its next step, what if we really know the absolute outcome of every recipe we make in life?    Not fake, not "The Truman Show".  What if our experience and judgement and data and correct premises were increased a thousand-fold, or by a million?   If we could almost intuitively anticipate the "butterfly effect?"

It might make life incredibly boring.   Would we be like cattle or ants, grazing?   Grazing on lots of different ideas and information, but all predictable, and it would pass through us like cud.

Or we might replace the "risk" and uncertainty by expanding our horizons geographically, taking what we know and are certain of, and placing ourselves in new frontiers.  "Star Trek" or "Dr. Who" is a way we can always imagine shaking things up, going to other solar systems, to seek out new worlds and new civilizations, and boldly go where no one has gone before.

Trying new foods is good.  Eat the same thing, every time, is like ... eating grass.

What if we actually make ourselves feel more in command of all information by reducing the amount of information?  What if we limit our geography so much that we really do know and can anticipate an extremely high percentage of what we encounter?  Instead of a hypothesis where we increase our intellect a million-fold, and then reach outside the solar system, why don't we shrink our system so that the intellect, intelligence, and data we have is preponderant.

If we put our butterflies in fishbowls, or vacuum tubes, their effects will be easier to predict.

When an African really wants to buy something from me... not everything, not all assorted junk, not 75% of the "e-waste", but something rather specific - say a 17" display screen (which will light up in a slum with electric current too weak for a 27"), I may have to admit I don't know what will "ultimately" happen to it.  Perhaps I cannot predict the fate of the monitor in our custody.

If we shred it together with the 32" TVs and obsolete printers and clickety keyboards, and spit out a stream of shredded plastic, shredded copper, aluminum, and steel, drawn by magnets, optical sorters, and eddy currents, then I don't really need Watson to make the decision what to sell anymore.   Everything is now a commodity, a stream of raw material.

Moo.

Recycling Slag: True Environmental Law

Slag is a partially vitreous by-product of smelting ore to separate the metal fraction from the unwanted fraction. It can usually be considered to be a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides (see also matte) and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting; and also minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal. [wikipedia 2012.02.28]
This definition of slag is similar to CRT cullet from recycling operations.  There's a big difference, however, in how the two are regulated.  Where you would like to think that regulation promotes recycling over mining of virgin mountains, the opposite is true.

Mining and smelting has defended the practice of piling up used slag from foundries in massive piles all over the Western USA, Canada and Mexico.    It was debated whether these piles had to be disposed, in landfills, or whether they were really doing no harm in the desert and (as the capitalist model goes), that smelters would come back for it to mine it again when:

A) the veins of lead in mountains (second to silica, the most abundant element in slag) became more expensive to mine, and the slag would become more attractive, and/or

B) technology which already worked in the lab would be economical enough to turn the slag into a commodity.

The mines get bigger and bigger and the slag piles got bigger and bigger.    How does the regulation of recycled "slag", or by-product, compare?

CRT Glass to Glass Recycling: Down For the Count?

Since the 1990s, environmentalists have had a strong preference for CRT glass to be remelted into new CRTs.  It preserves the value added by the barium and lead which is vitrified into the solid glass, and avoids mining of new lead and silica.  Given a choice between making a CRT television out of mined material, and making one out of recycled glass, it's no contest.

But word is that China is pulling the plug on its 20 year obsessive CRT manufacturing campaign.   They are sufficiently entrenched in LCD and LED display production, that they are turning off CRT glass furnaces.  "Time to move on."  We never really had access to export to those CRT glass to glass operations, and so China never really developed phosphor washing (at least, that they allowed anyone to use).   Now those markets have gone away, having never done anything but make CRTs out of mined material from Kunming and Mongolia.

The USA of course lost its last CRT furnaces a decade ago.  Europe lost CRT glass manufacturing 6 years ago.  Samsung Corning in Klang Malaysia did not retool and is giving out their purchase orders for cullet on a month to month basis.  That would leave India - which still sold as many new CRT units as flat panels this year - as the sold CRT glass to glass option in the world.
