Here are some specs about their functioning:
Let's say you are using the compost toilet.
This is when you deposit your manure or pee. Under the toilet seat, a composting tank has been previously prepared with a special "composting bed" (made of nutrients, like carbon) that ease the composting process and neutralizes the odors.
When you are done, close the toilet lid - a crucial step to keep the heat in and the flies out! And by the way, the provided toilet paper is made of recycled tetra pack, so no worries about throwing it inside the toilets!
The whole composting process is absolutely safe.
There are two ways of getting rid of harmful organisms: some human pathogens don't survive long outside the human body, so we rely on the time factor to ensure that they perish by keeping the pile of human waste inside the composting tanks for a minimum of six months.
Other organisms only go away with very high temperatures, which are very common in the Idanha-a-Nova region! For these organisms, we keep the human waste pile at 50ºC for 3 days. With time, along with high temperatures, most of pathogens in human waste eventually die.
