Apologies if this puts anyone off, but I’m really excited by this innovative way of dealing with sewage. Not only does it make something useful out of a big, smelly problem, it does so in a ‘relatively’ small space. [Conventional sewage works take up acres and acres and acres of land that could be used for other things].
To read how this innovative approach actually works, please read the article on New Atlas:
As a sci-fi writer I’m interested in all kinds of futuristic world building and one of my earliest ideas was for an ‘undercity’ built to replace much of Melbourne, post sea level rises that drown the lower reaches. Obviously, the new undercity would have to be built on much higher ground to avoid being drowned as well, but it would have lots of big advantages – temperature would remain more or less constant, bushfires would no longer be a danger and the land above the city could be used for productive agriculture. [At the moment, all Australian cities spread outward and our suburbs are built on land that would be better used for the growing of food].
One major problem with this undercity, however, was the issue of waste. I imagined food waste being ‘eaten’ by the SL’ick [synthetic life chickens that look like huge worms made of chicken breast meat], but I simply could not come up with an innovative way of dealing with the body wastes we humans produce. Until now. One small step for my world of the future, one large step for waste management. 🙂
