[Terrapreta] Charcoal in Compost? 4USA?

[Bernie Lenhoff]

Hi Tom,
 
I'll refer you to the Advanced BioRefinery web page for their
descriptions of their plants:
 
http://www.advbiorefineryinc.ca/oneton.html
http://www.advbiorefineryinc.ca/50ton.html
 
Our yard could probably utilize their 100 ton unit (which is essentially
a double 50-ton). But I wouldn't take us as necessarily representative,
since we aren't yet diverting a large percentage of the total local
green waste volume. Any substantial municipality processes more woody
biomass than we do, I'm guessing 100s of tons daily.
 
We certainly would entertain the possibility of being a producer.
Theoretically, the biofuel could also produce power for other parts of
our operations, including the wood mill. The promise of such a closed
system is enticing.
 
Realistically, however, at this point it would make more sense for us to
supply the biomass to a separate plant (if one existed), because of the
investment involved (in cost, permitting, etc.). We currently send some
of our biomass to cogen plants. If we had a pyrolysis alternative, it
would certainly seem preferable.

Bernie,

 

What is a "1-ton" plant? Is that 1 ton of biomass per day , i.e. 400 lb
char per day?

 

What size of charcoal processing system, in tons of waste wood/day,
would be suitable at a recycling yard like the ones you operate? 200
tpd?

 

Do you see charcoal products being produced at an operation like yours
or in a separate plant? 

 

Would you 

 

Thanks

Tom Miles

 

 

 

 

A demonstration 1-ton plant is about $60k, with their commercial and
higher capacity plants being far more expensive. A good current strategy
might be to encourage Waste Management authorities to put together
government/business/nonprofit/academic partners to set up demo plants
with associated research projects using the biochar and biofuel products
created.
