Re: Municipal sewer solids to biochar #biosolids

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.

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