Natural waste is something we distance ourselves from since the stone age and even before that because the smell is built into us as a way to keep humans away from diseases. It was natural back then but since our expansion of the human race we needed to somehow reuse the waste we create or it is going to build up faster than anyway we can dispose of it. Our disgust for waste is shown in our marketing and design of buildings where bathrooms are hidden except for their signs. Waste product disposal often nicknames the waste in more pleasant terms to seem more inviting as a product to buy. This shows the distances we go to as a species to separate ourselves from something that we have to do pretty often. Especially since covid cleanliness has become a top priority and natural waste could not be a part of it and if it was it will be separated from those who produce it.
