[Terrapreta] energy balance and emissions

[Duane Pendergast]

Great question Mariska! 

 

I suspect the energy use or production can vary substantially depending on
the particular process used and products produced.  I'm getting too old -
and lazy - to undertake any analysis needed to sort it out. I suspect the
technical literature might be productive. Google Scholar is helpful for
searching that if you don't have ready access to bibliographic search
systems.

Note the second hit in the above search today (07/11/13). Also not that it
costs $30 if you can't find it at a library.

Hello

Sorry if this has come up before, I'm quite new on this list and haven't
seen this discussed before.

I'm doing some research into the benefits and draw backs of biochar
production on a large scale,
which has led me into looking at the energy use and emissions of the
production process.

Has anyone found any publications or other information covering this, I have
pretty much exhausted the www and available literature on pyrolysis - but
they are all evading this issue.

I'm assuming that the energy balance of the production is positive - ie some
energy will be produced in the exothermic stage which will make up for the
energy used to set the process off - but I want to find some hard numbers.


Any info is helpful
Thanks
Mariska
