[Terrapreta] Net Present Value and Net Future Value of TPBenefits

[Greg and April]

Sean,

You keep talking how methane from making TP is so bad, that we may as well not make the char, I now feel that I have ask you to now show documention that backs up your words.


Sure methane is a more powerful GHG, but it is so reactive that once in the atmosphere, it starts breaking down, and is gone inside of 10 yrs.


OTOH, any char that is produced is here for hundreds if not thousands of years.

In short, any negitive effects of methane are out weighed by the positive effects of char, by over 1000 to 1 ( years ).


Don't get me wrong, I'm not saying that we should just go ahead and make char with nilly willy regard for the end results, because if methane is being produced, then the method used is in effecent because that methane can be rerouted back to be burnt to make the char - thus saving on the fuel needed to make TP in the first place.

What I am saying is that we shouldn't get so wrapped up in not releasing methane that we never get started in making TP to begine with.

In short, methane is small potatoes when compared with the amount of CO2 released when we make char - but we know that the CO2 is carbon neutral, what you are appearing to forget is that the methane is also carbon neutral, and also comes back as more biomass.


To be perfectly honest, I would actually like to know how to produce a liquid that is useable in a diesel engine from the process of making TP - at least then I can power the equipment used to collect and process the biomass, making it ready to turn into TP.
