How Long Does It Take Human Poop to Decompose in an Outhouse?
Waste does not decompose in traditional outhouses as there are no other organic materials added. Some owners use lime to get rid of the smell and initiate the breaking down process.
However, to fully decompose, the poop needs to be scooped out of the outhouse and only them composted.
How Long Does It Take Human Poop to Decompose in a Chemical Toilet?
Human poop does not decompose in a chemical toilet. The chemical mixture used in the holding tank only conceals the contents of the tank and suppresses microbial growth.
Once the tank is full, it needs to be emptied and the waste has to be composted. The holding tank should be emptied every week or so.
Does Poop Compost Decompose into Soil?
Once the compost is ready, it had already decomposed into small soil-like particles. Such nutrient-rich soil is the end-product of the composting process and it will no longer decompose.
According to the University of Illinois, adding compost to the soil in gardens will be beneficial for the plants. However, human waste has to be brought to high temperatures in order to kill harmful bacteria before being used in the soil.
Is Human Poop Compost Bad for the Environment?
UK scientists state that human waste can have great fertilizing potential – it can provide organic matter that contributes towards reducing erosion and building soil structure and can provide essential plant nutrients.
Human poop compost can be bad for the environment if during the production process harmful bacteria and pathogens were not killed. For that matter, homemade composting systems are rarely approved by the local sanitation authorities.
Does Poop Compost Evaporate?
Yes, composting toilets rely on the processes of decomposition and evaporation to recycle human poop. In most cases, 90% of the waste will be water, so this part is going to evaporate extremely fast.
Depending on the composting method used, water is usually evaporated and carried back to the atmosphere through a special vent system.
Why Should You Bury Your Poop Compost?
If the poop compost has not been heated up to a high temperature, it might still have harmful bacteria. In such a case, the best decision would be to bury the human waste compost as it won’t impose any danger.
Make sure to dig a hole that is about the length of your hand and that is at least 70 steps away from campsites, tracks, and water. Cover the waste with soil and organic materials and let the decomposition control diseases and odor.
Is Human Poop Compost Good Fertilizer?
Yes, human poop has a good fertilizing potential. For example, it can help reduce erosion, build soil structure, and provide plants with essential nutrients.
But a lot of municipalities recommend using human waste compost only on flower gardens (not vegetable gardens or fields).
Is It Legal to Dump Composting Toilet Waste in the Ocean?
According to the USCG rules, a composting toilet is a Type III marine sanitation device, which means that people can use it anywhere they like, but they cannot dump the composting toilet waste in the water anywhere inside the 3-mile territorial limit of the United States.
Does Anything Dissolve Composting Toilet Poop?
Various bacteria will help break down composting toilet poop with the help of oxygen, but you can’t really fully dissolve the compost (unless you are using extremely strong chemicals).
However, composting toilets still help you drastically reduce the volume of human waste and turn it into ‘healthy’ soil.
Can You Throw Away Human Waste?
Human waste can be potentially infectious, that’s why it has to be handled with care and, ideally, composted. Six federal land management agencies have rules against dumping human waste on their lands, so it is illegal to throw away compost human poop.
Does China Use Human Waste as Fertilizer?

What Countries Have Used Human Waste as Fertilizer in the Past ; Present?
The Aztecs, for example, made special islands out of human waste to grow crops. Today, China, some countries in Africa and Central America, and others continue to use human feces as fertilizer.
In the United States, almost 50% of biosolids created are applied to land (mainly, in agriculture). Moreover, plenty of Americans choose to compost their own waste and use it in their gardens.
How Do You Speed Up the Decomposition of Human Waste?
Step 1
The portion of human waste should not be too large. The smaller the starting material, the faster the composting will take place. So, make sure to break up the waste.
Step 2
Add additional bioorganic mass. Don’t leave the feces in their ‘pure’ form. Mix them with leaves, grass clippings, coffee grounds, etc.
Step 3
Stack as loosely as possible, to ensure there is enough oxygen.
Step 4
Add earthworms to speed up the process.
How Can We Reuse Human Waste?
There are different ways in which we can reuse human waste:
- Fertilizer
- Production of biogas
- Fecal transplant (delivering feces from a healthy person to the patient who suffers from clostridium difficile)
- Brick-making
- Hydrogen fuel
- Source of metal ($13 million worth of metals can be extracted from the feces of one million Americans)
- Source of water
