Hello everyone. I've just begun researching composting, and I was surprised that googling "composting forum" actually came up with pages of results for forums, much less for posts on the subject, so I'm a bit overwhelmed. There is a huge body of (very dispersed) knowledge out there, but most of it seems to be oriented toward producing generic fertilizer rather than a particular set of chemical components.
Likewise, should one dare to search amazon books for "composting", there are a veritable plethora of sources. Unfortunately they too are focused on the resulting mixture and levels of K, P, Ca, and other nutrients taken as a whole.
What I'm looking for is information which can take me towards a composting system where mammal urine goes in one end, and a liquid stream rich in soluble nitrates exit the other. The other products (methane, solids, etc) are completely secondary.
I see MANY general texts, webpages, etc., out there. I've familiarized myself with a lot of them. Can anyone recommend a text, paper, webpage, or expert who might take me "the next step" toward my goal?
Thank you for your consideration,
The short version of the reason that I'm doing this project is: I have a stream (no pun intended) of urine on the order of 10-100L per day, and I'd like to turn it into something useful rather than dumping it down the drain.
Ammonia is one possibility: Drop in some urease from dried soybeans and capture the ammonia via air-stripping. Simple, but there are two downsides: First, the volume doesn't change much (urine -> NH4(aq)) Second, leaks are smelly.
On the other hand, if I can further bioconvert the urine/ammonia to nitrates, those can be dried and transported easily, and have no odor in the case of a leak in the system or the transport.
Please keep the ideas coming! I'm open to any suggestions out there, in terms of chemistry, physical setup, "right" compost mix, temperature, etc.
All help welcomed thankfully
