I'm a sci-fi enthusiast, and I love digging into movies that explore futuristic tech, especially the weirdly specific ones like bio-toilets. One film that comes to mind is 'Snowpiercer,' where the train's ecosystem includes a recycling system that hints at advanced waste management, though it’s more dystopian than glamorous. Then there’s 'The Martian,' where Matt Damon’s character deals with waste in a high-tech survival scenario—definitely not a glamorous topic, but it showcases practical sci-fi solutions. Japanese anime like 'Ghost in the Shell' also sometimes touch on hyper-advanced infrastructure, though not toilets specifically. Bio-tech in movies is usually about flashy things like cloning or cybernetics, but waste tech? Underrated!
