Do you have any recommendations or examples of the best methods to absord/adsorb the collected urine into the biochar ie. proportions for the mass of biochar to the volume of urine
and the use of commonly available materials etc.?
Are there additional advantages resulting from the fermentation of urine that make charging of the biochar more effective, other than odour prevention and N - Loss?

I also think that incorporating biochar in any way feasible would be fantastic. I don't know if your municipal area allows burning of wood waste at the landfill, but maybe a pit for charring would be a short term compromise (in lieu of a retort or something) that could give you a lot of charcoal cheap and fast. With a backhoe you could dig the pit, feed the fire, and bury the coals to cool pretty easily
