1) first find the landfill
2) what's in it? usually nothing of interest
3) ugh, imagine what you'd have to wade throug to find any recyclable metal
As evidenced by what we see in many parts of the world, there are people
who will now do that picking. Maybe robots will do it more easily and
humanely. Similarly, your average waste pick-up company (at least here
in the States) is already harvesting as much as is easily picked out
by machine or human. After all, they're charged to put it in a landfill,
and they're paid to deliver a bundle of cardboard or plastic or scrap iron.
In your average modern anaerobic landfill, they're already harvesting
the methane from the decomposition of the organics. When you did hit
something plastic or metal, you know it is more concentrated than your
average strip-mine ore. It might not be what you really wanted to find.
Sure, it would be nifty if we could reduce it all to plasma and sort
by atomic weight, but I don't think energy will ever be that cheap.
Around here, the scrappers and recyclers are always eager when I tell them
I'm giving away a few big boxes of motherboards and power supplies.
