Monument to Civilization: Vertical Landfill for Metropolises:
Skyscrapers are meant to wow, to impress. But other things within cities are also impressive, [Lin Yu-Ta] says: “New York, for instance: If we put its annual garbage on a area of a typical tower footprint, we’ll get a 1,300 meter high landfill tower, which is about as three times tall as the Empire State Building (450 meters). Isn’t that spectacular?”
Scarily enough, this actually strikes me as a potential workable solution. Especially if we could find a good way to tap into the methane and heat of decomposition for power generation or other uses.
That’d be one hell of a compost pile.
