I have just discovered that those odd waste/recycling bins that are all over the oldest bits of Bergen, Norway, link to an UNDERGROUND PNEUMATIC WASTE TRANSPORT SYSTEM. The waste collects for a bit and then WHOOSH... it's off to the recycling centre. All underground. No bin lorries (garbage trucks), fewer road vehicles, less noise... amazing. @davidho says that my (considerable) excitement about this is entirely unreasonable. I disagree. https://www.envacgroup.com/how-it-works/the-envac-system/
