> I'm surprised that most people didn't pre-burn their dried feces before using it as fertilizer This paper is about incineration of sewage sludge. They consider incineration at temperatures like 700C to 900C. Seems like you end up burning 98% of the nitrogen, which is then released as gas (bottom of page 12, just before Conclusions). The output ash only contains 2% if the input nitrogen. Kind of defeats to point of using the output as fertilizer. https://sci-hub.se/https://doi.org/10.1021/acs.energyfuels.5b01109 https://sci-hub.se/https://doi.org/10.1021/acs.energyfuels.5...
