Recycling Glass


In the texture recycling collection I'm aiming at what the texture of piles of specific substances look like waiting to get back into the stream of things.

Here is a view of the surrounding area.  Each of the piles has roughfly the the same characteristics:  large broken glass on the top, smaller particles of glass inside.

Here is the top of a "young" pile ...

recycled rubber tires:


Here is what tire recycling looks like early in the process.  These are being staged at a Rabanco facility.
I watched rubber tires being recycled on the Science channel to make rubber mats , hoses & more tire stuff.

Well, glass is not likely to turn back into sand.  Sand is not likely to turn into dirt elsewise the deserts would become arable again.

Well glass broken into fine particles is sand.  I have no doubt that the finer partiles in the pile of glass came from the bigger particles.  What i don't know is the process that broke the larger into the smaller.

If you scratch one of these piles of glass you see a finer brown particles.  It's almost as if  the glass is biologically degrading.  I wonder if they add some substance to the pile to do that.  The picture below is from a old pile that i found along the BNSF railroad ... it was probably abandoned decades ago. 

A thin dump site with dirt under it ?  Glass won't recycle back into dirt.  It is melted sand.
I seriously doubt that they made a mound of dirt and then piled broken glass on top of it.  If you go to the album and take a look at the zoomed image you will see that it does not look like dirt.  When i get a chance i'll try to get you a close up picture of the innards of the pile.

I don't think that glass broken into fine particles is technically sand. Sand (quartz) melted to a high temperature with additives = glass. I suppose you could make sand by extracting the additives and crushing it down to just the quartz, but the entropy of the process is little worth it. See the wikipedia on glass: http://en.wikipedia.org/wiki/Glass

I'm sure your right.  Can you shed any light on how the larger particles of glass became smaller particles of glass?

I don't think your assumption is much good except for shifting. I doubt there is something natural or unnatural causing large pieces of glass to change into smaller pieces. When you shake a pile of peanuts the larger pieces sift to the top. The sea & erosion change the shape of rocks etc. Perhaps the dumping process stowed the glass that way. Perhaps vibration in a dump truck going down the highway shifts the large pieces to the top of the truck bed & then the dumping of the truckload puts the smaller pieces together.  Anyway recycling broken glass into glass objects is useful because all of the energy transforming quartz sand into glass has been done & less energy is needed to reform it.

When i originally saw these it struck me as an anomoly.  But then i observed another site, separated by many miles, that exibited the same pattern.   Frequently recycling operations leave piles of homogenious materials behind for purposes of staging.  There are two piles pictured that are relativitily homogenious: this one along the Duwamish, and this one anlong the BNSF tracks.  Homogenous piles is what you would expect if the glass was crushed and then staged in a pile.  I think that rain, over a period of years, would naturalluy sort the finer particles to the bottom even if the pile started out being relativetly homogenous. But that does not explain the wide variation in particle size observed here, here, and here.  Lots of things could have hapened:  perhaps large broken glass was dumped on glass that had been crushed,  or perhaps partually crushed glass was dumped before it had been sorted.  If i were to bet, i would bet on the latter. 

I think the BNSF site has been abandoned and/or forgotten by it's owner which was probably Rabanco which is just on the other side of Monster road.   I have no clue who owns the other site close in to the port  ... it's behind several businesses that could have a stake in it.  There is one other site, i have seen, that has a pile of recycled glass before it has gone through any processing.  I think it is possible that piles of glass get sidetracked from the main flow of recycling and then sit for years because nobody knows what to do with them.   The "beautiful" one in the picture below is perhaps a case in point (look at the magnified view in the album).  When does glass recycling turn into sculputre?

Also, rain is likely to wash the smaller pieces of glass to the bottom of the pile.

I agree. (1) Rain is probably the primary sorter.  ( 2) Crushing machines are probably the primary means of making smaller from larger.  I think (3) piles getting sidetracked from the main flow is a potential explanation of why these anomolougous piles exist.  It's fairly obvious that piles of various things sit for years and years before sombody figures out what to do with the stuff ...


Mark de LA says
Fascinating!  I would think technically that glass or any other material which is not yet turned into something else such as a hose for rubber or another bottle from broken glass is not yet called recycled.   The science of piles of stuff probably has a name.  Some do study piles for earthquake, building & waste disposal purposes - yours ?

Seth says
For the record, before i leave this obsession with piles, here is the unhomogenous pile near the port.  This is the pile from which the zoomed image in the item above was taken.  The dome on the upper right is used to store piles of sandy looking dirt by Ash Gove Cement.

Well in general i'm just trying to percieve processes that are not well documented in conventional media.  Frequently these processes take place behind signs that say  no Trespassing ... these are private piles.  Recycling takes place from pile to pile.  Below is a pile of cardboard destined to be compacted in bales and then transported to the port ... probably T105.  I was privledged to add 80 pounds to the pile for which Sea-Dru-Nar Recycling paid me $2.60 ... $65/ton ... best prince in town


Seth says
Actually i need to revise that ... recycling takes place between piles and bales ... below is a pile of rusted metal in front of a stack of bales of compacted plastic bottels.  The picture is from the General Recycling of Washington Dock Facility at Terminal 105 along the Duwamish waterway off West Marginal Blvd.
