Municipal sewer solids to biochar #biosolids
Helmut Gerber
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
Helmut Gerber

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

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

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