Clean Streets: Piping Out Trash Below Cities in Pneumatic Tubes

Garbage trucks have gone missing in cities around the world. In neighborhoods from London to Barcelona and Singapore to Seoul, their unmistakable sight, sound, and smell are notably absent. The reason? Trash has gone underground, whisked away through a hidden network of pneumatic pipes—no trucks, no noise, no stench. If this sounds like the future, it is. But this particular slice was invented in the 1960s by Swedish company Envac. The company’s CEO, Joakim Karlsson, joins Supercool to discuss how Envac is taking trash removal to a whole new dimension.
