[Terrapreta] energy balance and emissions

[mariska evelein]

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
