We descend underground. The stairs reverberate with metal clanging with each step. We are in the belly of the port, a bright green vessel before us, with blue and green pipes in and out, Pompidou style. I am looking at the inner workings of the Stockholms Hamnar waste disposal system.
This is where trash is sucked from the self-emptying litter bins scattered around the port; from the larger bins where ferries unload the coffee cups and breakfast dishes of commuters and tourists weaving between the islands of Stockholm’s archipelago; and from the kitchens of the nearby Grand Hotel.
David opens a steel door and shows me several large motors running the vacuum which suck the port’s rubbish. There is a smell certainly, a faint unmistakable tangy stewing of waste, but it is dampened and really not as strong as I would have expected in a tight space of compressed garbage. David shows me the plans which sketch the underground system, with vents for air to enter and leave the system. He points out where the garbage is compacted and then raised to street height once a container full, for truck collection. No-one works regularly down here he tells me, it is a station run remotely. Indeed there are few signs of humans, besides a pair of grease-smeared gloves and the emergency escape tunnel in case someone gets stuck.
It’s stopped raining by the time we step out from the underground chamber. As we stroll to the metro, David tells me that one of the reasons Envac won this job was because their solution meant quick removal of large amounts of garbage, without it piling up. He shows me how the inner sensor works in the bins, which monitor their fullness. As a glass recycling truck noisily empties its load behind us, we talk about the future of cities and the role for vacuum waste disposal in dense urban spaces increasingly excluding cars.
As we hurtle underground again,
this time on the metro, David tells me about the strange things that are found
in the systems they service – Christmas trees and whole bikes for example. I
ask if they are ever contacted to retrieve valuables – “Yes!” he says, people
have their wallet/keys/phone in one hand and the garbage in another and before
you know it the keys go in the trash tubes and they are left holding the
garbage. Passports have been known to go in too. I can just imagine. I know
that tingly urge to throw something off a bridge and often worry that valuables
will go down into the depths of the underground, when I recycle in my local communal
bins.
