[Terrapreta] carbon and compost

[Edward Someus]

Tom, 

Tks for response. 

The field demonstration carbonization plant I  have in Hungary is for
testing and not for industrial production. My large scale industrial Clean
Coal carbonization plant is under construction, which will be commercially 
implemented in the US Illinois in 2008. 


RE CHAR COSTS + ECONOMY
The estimated carbonization cost $25/tonne for coal input in a CLEAN COAL
project might be close to real, but not necessarily for biomass. Biomass has
less specific weight than coal m3 vs weight, provides lower carbon yields
and most importantly the logistic costs of the high volumes is local /
regional specific. The pyrolysis oils can economically be utilized, with
consideration of the main alternative to burn it off directly and recover
energy. Modern carbonization technology is a complex design and may often
contain site specific solutions as well. Therefore, feed material + logistic
optimization has important influence on the total costs, especially for
bulky materials, such as biomass. 


I am dedicated supporter of the TERRA PRETA concept. I am also making
extensive carbon in soil tests in several European countries (Italy, Israel,
Hungary, The Netherlands, Germany, UK), which high science project also
supported by the European Union, Directorate General Food Safety.  One of
the prime objective I have is that parallel with our US Clean Coal programme
is to further develop the 3R technology for economical terra preta
application. The new 3R technology opens new technical, economical and
environmental opportunities. 

I would be happy to find scientific, technical and business partners to
implement the 3R pyrolysis technology towards terra preta concept.
 
Thank you

Edward,
Good question. $20/tonne will usually only pay for preprocessing biomass to
a fuel or feedstock. It will not pay for making a product.   
Processing only, no biomass cost. Our economic analysis shows that char must
be produced as a co-product of oil, heat or power for the charcoal portion
to be processed for $20-25/tonne biomass. We’ve looked as much as possible
at operating plants. There aren’t many. We haven’t taken a detailed look at
a plant to produce only char. We don’t have information for large volume
commercial charcoal plants. Our processing estimates for  100 and 200 tpd
plants producing oil are $90/tonne and $65/tonne. Of that $20-30/tonne is
for capital, $45-$60/tonne biomass is for operations including labor. We
estimate that labor is 20% to 25% of processing costs. Processing costs
increase about 40% for the smaller plant. 
ABRI does not have a system in commercial operation yet. I took the ABRI
estimate in the article cited at face value, as stated. They estimated $2/GJ
and 10 GJ of oil per tonne of biomass so $20/tonne of biomass. 
Fuel costs. $20/tonne is a reasonable place to start. As I stated our
delivered urban wood costs are about $20/tonne. Actual costs are higher but
they are offset by fees and subsidies. We remove field crop residues at
$20-25/tonne. If you have to put them in storage and deliver them to
processing on a year-round basis then the cost goes up to $45-50/tonne.
Forest residues delivered to the nearest location where they can be
processed are $20-$50/tonne.
What are the biomass and charcoal processing costs in Hungary?

QUESTION
 
Which of the modern pyrolysis system (that meets new environmental and
agro-industrial regulations)  cost $40 to harvest and process a ton of
straw?  ($20/ton harvest and field side/store; $20/ton to Process; 20% yield
of char) as of your specification?
 
Could you pls identify at least one modern and operationally viable
pyrolysis unit in industrial scale in the Western World that meets US/EU
standards and still cost as low as $40/ton production?
 
Tks
