If manure from animals that are herbivores can be used for compost, then what about human vegans' waste?

Answer 1

No, as I recall from somewhere the human digestive system is much more efficent so most of the nutrients are absorbed out....I've heard in some countries like cambodia and other south asia they use it for fertiliser anyways despite the low nutrient value for plants.

Answer 2

Human waste can actually be used for manure, and although it's not necessarily the best, it's certainly the most abundant and therefore potentially the best source. It's false that human manure is less nutritious. The most popular book on the subject is "The Humanure Handbook", which advocates composting your own shi!t. In fact, the only reason we DON'T use human feces as compost/manure is because we flush it down the toilet, where it gets mixed with all sorts of other sludge and contaminated with heavy metals, etc. More intelligent use of our waste would not only prevent vast amounts of water pollution, but would allow efficient use of organic fertilizer.

The major drawback with human manure is that it may contain human pathogens, and indeed is far more likely to transmit such pathogens than the manure of other species. More effective and thorough composting is necessary to prevent this from being a problem.

Answer 3

human waste is and has been used all through history

in china it is put above the ground directly on the plants ,this is called night soil ,and it is not very good because the excrement does not go through a decomposition process and can transmit diseasesonto the products,
in thailand people build beautifull toilets with aromatic herbs and decoratively painted ,and invite passers by to make use of their toilets ,they add sand and the decomposed manure is used for their gardens ,this is very good

the Aztecs collected the material from the public toilets which where on the bridges going into the city and mixed it with the rich mud from the lake and organic waste(cuttings from plants)
this is very good and the agriculture of the chinampas is still functioning and is sustainable after 800 years ,

In portugal the old toilets were raised of the ground with a stairway going up and one deposited ones poopoo directly ino the pigs through
not such a good idea ,also because of diseases.

a lot of Environmental sewage systems have plant growth as the final destination
one has a normal water toilet system ,that goes into a concrete box about 2square meters next to another one connected with an opening at the bottom of the shared wall,the excrement floats and stays in the first box the seccond box has an outlet that goes into a ditch filled with rocks ,on top of this one plants trees and the sewage is directly incorperated into the fertilizing of the garden ,with out bad effects
another way is to have a worn cultulture that exchanges the excrementfor a rich worm compost ,
the best fertilizer in the world

Permaculture has a book called the designers manual ,it has many examples of sewage sytems as a well as a wealth of relevant information

Answer 4

Technically, it can. However, if you compare our digestive tracts to the animals whose waste is routinely used for fertilizer, such as cows or horses, ours is quite different. For that reason, no, even a vegan's waste wouldn't be very nutritional for plants, which would make it useless.

Answer 5

Yes,and they do,the government comes to my house and takes my poop for making compost.

Answer 6

Human excreta can be used as a fertilizer in fact urine contains urea, which is a popular fertilizer.
