Dewetting sewer solids will take a lot of energy, but carbonizing degrades plastics and pharmaceutical, the bugaboos of sewer waste recovery efforts.

This is how they do it in Kenya. https://www.treehugger.com/kenya-fecal-briquettes-are-serving-clean-cooking-fuel-4857062

Ingelore and list

Unfortunately,  these charcoal briquettes have nothing to do with biochar.  One definition of biochar is charcoal that is not combusted.

Would fecal char be safe for use as biochar?  I know our current challenge for use of sludge in agriculture is pollution such as anti-biotics in material.  Would the heat of pyrolysis destroy those threats?  Otherwise, it is a feedstock that forms to the size of the retort, unlike wood that must be cut into small pieces.

Australia's first Biosolids gasification plant is now in it's final testing phase in Loganholme, Queensland. Congratulations to James Joyce and his team @ Pyrocal! https://www.youtube.com/watch?v=uD3O9cY26-Q&feature=youtu.be

Hello,
at sufficiently severe pyrolysis conditions (> 500°C) and residence times (> 3 min), all
reference organic contaminants and organic micropollutants are completely or nearly
completely degraded or driven off the solid material.
( Literature review attached)
 
Best regards
