[Terrapreta] a braoder theory of torrefaction and TP

[Sean K. Barry]

Hi Lou, Duane,

There is a scale of improving effect from reducing "carbon positive" activity (conservation), to "carbon neutral" (using biomass renewable energy), and finally to "carbon negative" (carbon sequestration).  Maybe it might be worhwhile considering that "carbon credits" could be paid along a similar graduated scale, as well, making "carbon negative" activities earn the highest value of "carbon credits" ?

What might any of you think of that?  I think it would promote the formation of Terra Preta, in lieu of others schemes for ACTION to combat Global Climate Change (GCC).

Regards,

SKB

  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.
