The average person produces about a pound of poop a day. Where does it all go? The answer depends on where you live. If you have a flushing toilet, your metabolic output spirals down the underground pipes to massive wastewater plants that clean the water and dispose of the rest the best they can—by destroying or landfilling it. In places where flushing systems aren’t possible, residents build cesspits and outhouses, where sludge accumulates and eventually needs to be emptied.
Because excrement spreads diseases, people put a lot of effort into getting rid of it as quickly as humanly possible. But now, scientists and engineers are telling us that we’ve been wasting our own waste. When recycled properly, this cheap, fully renewable, and readily available substance, regularly produced by all 7 billion of us living on this planet, can grow food, cook dinner, fuel cars, and generate electricity. Here are a few cutting-edge technologies that are already upcycling people’s poop—and may get to yours soon.
