But not all poop ends its life by fire or burial. Some human waste ends up in forests and farm fields as the treated, human-feces-based fertilizer known as biosolids.
Does flushed poop end up in landfills?
A significant portion of flushed poo, in fact, ends up fertilizing crops that we eventually eat, said Daniel Noguera, a civil engineer at the University of Wisconsin-Madison. Some of our poop gets used as fuel, heating the very facilities that process our waste. And the rest eventually reaches landfills.
How much poo does an average human flush?
Humans produce a lot of poo. An average adult flushes about 320 lbs. (145 kilograms) of it down the toilet each year. But what happens to all that waste? It turns out that the stuff we flush down the toilet is surprisingly useful.
How many stages of wastewater treatment are there?

What are the pollutants in poop?
Billions of microorganisms that are already in the poop breathe in oxygen and munch on pollutants such as nitrogen and phosphorous, cleaning the sludge in the process. These pollutants could otherwise cause massive algae overgrowth in waterways or react to form toxic compounds, like ammonia.
When will biosolids stop going to landfills?
New York City, for example, is aiming to stop sending biosolids to landfills by 2030, according to the New York City Department of Environmental Protection. There's even a push to increase our use of biosolids as fuel. (Imagine a poop-powered home!)

What is the second treatment of water?
The now slightly-cleaner-but-still-brown water is passed onto what’s called "secondary treatment," which makes large-scale use of microbiology. Particular species of bacteria are added, to feast on the dangerous pathogens present in the feces-filled wastewater.
Why are bacteria added to wastewater?
Particular species of bacteria are added, to feast on the dangerous pathogens present in the feces-filled wastewater. Because these bacteria rely on oxygen, air is added at the same time, allowing them to thrive and multiply. Once they’ve broken down all of the pathogens, the bacteria have done their job.
Why do bacteria need oxygen?
Because these bacteria rely on oxygen, air is added at the same time, allowing them to thrive and multiply. Once they’ve broken down all of the pathogens, the bacteria have done their job. The water is moved to another tank where is it filtered and disinfected, and then, it’s ready to be pumped back into our homes.
