[Terrapreta] Strong warning against "simple" charcoal kilns

[Edward Someus]

Lorenzo, 

YES, I fully support  your notice and share your opinion. 

The "simple" or open or semi open charcoal kilns makes harm + damage for the
TP policy and marketing strategy. 

An modern TP char production must be zero emission solution or at least near
zero emission and meet the EU/USA advanced industrial standards and norms,
including all Authority permit procedures from all the different Authorities
 At least this is the technology concept  I work after for my 3R
carbonization technology development. 



Sincerely yours: Edward Someus (environmental engineer)

It has been repeated here a few times. We should be careful not to ruin the
potential of Terra Preta by coupling it to inefficient, GHG emitting
charcoal devices.
 
Many of these simple devices are 10 to 20% efficient at best. Biochar's only
way to make a difference is by using highly efficient pyrolyser units that
maximally exploit the energy content in the biomass and that minimize GHG
emissions. Syngas, heat, pyrolysis oil - all these he byproducts must be
explicitly used to offset fossil fuels. 
 
So I urge all of us to limit references to "simple" charcoal kilns, and then
only in the context of biochar trials that look at the effects of char in
soils. For the rest, I think we should continuously stress that one of the
most urgent needs is the development of highly efficient pyrolysis units.
 
Else, we could be ruining the entire Terra Preta venture. Remember, there
are many people reading these texts, and they may spread amongst journalists
 If they get the impression that we are a bunch of people who just pyrolyse
our way through this concept, then the initial potency of the very concept
may get lost. 
 
Cheers, 
Lorenzo
