[Terrapreta] a braoder theory of torrefaction and TP

[Duane Pendergast]

            Lou,

 

A knee jerk response would be to suggest it would have to be measured and
accounted for at the time of application. Once on the land it would be hard
to retrieve - unless we piled so much on it became flammable - yeah! Sure!
in my dreams!

 

Since the problems with monitoring an emission control system are
potentially so vast, it would sure be great if the economics of soil
enhancement could trump the economics of emission reduction credits

I like it Duane, 

I believe that credit would also have to require that the char be amended to
soil. The problem is that char can be used as fuel which would move it from
carbon negative to carbon neutral.

So here's the logical question: can the char be made into a form only
suitable as a soil amendment? Or are we looking at inspections and controls
to prevent diversions into fuel? 

hugs,   lou




To repeat, I'm suggesting that practices such as the burying of organic
waste in landfills might need to be phased out in favor of char production.
That would be a way of capturing the hydrogen component of organic material
and extracting some energy. The only credit allowed would be for the char
component. That would move us toward a carbon negative system, rather than
carbon neutral that comes from burning or producing methane subsequently
burned from waste.
