It’s National Raspberry Cream Pie Day, in these United States.

This is how it all works, this municipal recycling business.

Pictured is the Sims Metal facility in Sunset Park Brooklyn. Department of Sanitation performs its collection task using packer trucks – which work curbside pickup routes, essentially – and then they head over to a transfer station of either terrestrial or marine nature. On their way in to the transfer station, they drive over a scale and are weighed.

Once the trucks get past the scale, they wait their turn to “tip” or deposit the cargo they’ve collected.

This is done in a fairly orderly fashion, with a Sims Metal employee directing the DSNY operator to a certain spot where the driver activates the mechanisms within the truck which push the garbage out. My understanding is that the hidden internal machinery is driven by steel cables which tension pulls a plate forward from the back of the hopper, and that’s (plus the angled hopper for a gravity assist) what pushes the load out.

If the material was collected from Boroughs other than Brooklyn, it’s brought in by tug and barge from one of the other Sims facilities like the one found at Newtown Creek in Long Island City. According to one of the Sims people I met, they said a barge carries the equivalent of a hundred garbage trucks worth of recyclables all at once.

Once DSNY has handed off the recyclable waste, a bull dozer like unit moves it into a drop shaft which in turn feeds it into the highly automated processing room.

There’s optical equipment that sorts plastics and glass by type, as well as fairly esoteric bits of kit which feature magnetic or electrical flux fields which capture the metals like steel cans and aluminum foil.

The shapes and sizes of these moving conveyor belts also figure into the sorting and handling typology of waste.

I was told that a lot of this technology has been adapted from the agricultural industry – Big Agra, as it’s known – and that the biggest “players” in this sector are German and Dutch manufacturers.

Once this mingled pile of waste products has been separated out into distinct types (including separating the different forms of plastic) they’ll be bundled up and be prepared for shipment.

Plastics and glass are fairly worthless, it should be noted. Low oil prices over the last decade or so has caused the price of chemical feedstock for plastic manufacturers to plummet, as said material is a byproduct of petroleum refining and manufacture. That makes it cheaper to make new plastic than it would be to recycle old plastic. Glass recycling carries a pretty high energy cost, in terms of making it molten, so it’s mainly used a crushed up fill material in concrete and asphalt. That’s why some roads and sidewalks appear to shimmer in the sun.

Paper pulp is quite valuable, and VERY recyclable. So is metal, especially aluminum and copper. That’s based on the expense of producing new pulp, or refining mined ore. Sims Metal Management is a global corporation, and participates in a commodities market for these recyclable materials, which it sells (hopefully) at a profit internationally.

The DSNY trucks, meanwhile, having emptied their cargo into the Sunset Park facility, follow a certain path back out.

It carries them onto a second scale, just like the one they encountered when entering Sims. The differential tonnage between the weighings is what Sims bills New York City for their services.

Presumptively, this truck will head back to wherever it’s stationed to take on fuel and new crew, and head back out to perform more collection duties. Additional presumption would offer that it would likely end its next shift right back here at Sims Metal.

Well… as I said at the top of the post – this is the way it all works. Also, let’s all try to use less stuff that we can only use one time before throwing it away. Can you just imagine what all of this costs?
