That too but also, from the Nature article:
:
"Biochars are carbon-rich soil additives derived from agricultural and
other plant waste that could enhance crop productivity (see *Nature* *517*,
258–260; 2015 <http://dx.doi.org/10.1038/517258a>). We suggest that
biochars could also be produced from human sewage — an underutilized
resource that is rich in soil nutrients and carbon.
Sanitation problems in developing regions would be alleviated by diverting
sewage solids into producing biochar, made by thermal conversion in sealed
containers. This might even offset the need to install conventional
sewage-treatment infrastructure with its higher construction and operation
costs."
