[Terrapreta] agri-char market price.

[Adriana Downie]

Sean,
 
This is not at all a straight forward question. Economics need to be
done in combination with an LCA (life cycle assessment) to ensure the
comparison is fair and that we are actually do more good than harm. If I
wasn't an engineer with professional responsibilities to meet workplace
health and safety and EPA regulation then I could make Agrichar, as they
do in the third world, cheaply. However this comes at a cost. When you
do the LCA on these traditional methods, factors like particulate
emissions and greenhouse gas emissions mean that you are probably doing
more harm to society and the environment than you could justify with any
benefit achieved through creating Terra preta. Of course with modern day
engineering we can manage the environmental impacts but this requires an
industrial type processing plant and therefore scale to make the
economics work.

Hi Brian,
 
Your proposition that charcoal amendments to soil @$200/ton return that
investment in a year is very interesting.  It seems like a thing worth
measuring.  I don't know that anyone has tried to calculate the ROI of
making "Terra Preta".  It is an obvious valid question for anyone in the
business venture of producing agricultural use charcoal from biomass.
 
What do you think about how one could go about measuring this?

Hi Brian,
 
I'm sorry.  I saw that was probably a typo ($ vs 4) 0 also, but after I
typed my last message.  Still, how it adds $200/per ton worth of value
to the soil in a single year seems high.  Especially, considering
application rates of 5-10 tons per acre.  So again, where do you get
that $ value added number after paying $200/ton to buy the stuff, let
alone distribute it?

Oops...obviously that typo 4 shoulda been a $ :)

And I ment at $200/ton, the land owner comes out pretty decent. Once TP
catches on...$200/t will be the 'good ol days'.

Hello Brian Hans,

Welcome to Terra Preta.  Yes, that $200/ton price has been mentioned
before.  Where did you get that phenomenal ROI of 1 year, even at
$4200/ton?!  I live near Stillwater, Minnesota and I will be producing
biochar.  Call or write me if you are interested.

  Group,


  I am curious as to the market price for agri-char. I have read ~
$200/t
and
  am looking for some confirmation. 

  Seems like a steal for the benefits and that ROI is about 1 year with
  4200/t pricing. 

  Also...is there anyone near NE Wisconsin that is producing agri-char?
I
  would like to talk.

  Brian Hans
