[Terrapreta] sewage sludge charcoal

[Shengar at aol.com]

I learned this week that Dr. Ablevor at Virginia Tech has received his  
delayed  Dept Of Environmental Quality (DEQ) air quality permits,( they had  no 
category other than "Incinerator", I contacted DEQ's air guy and sent him  info 
from EPRIDA) and so can now ship the fluidic bed reactor  from Colorado to 
Virginia.
 
Still no date for the demonstration when I spoke with him last  month. He did 
say that he has done much work on improvements to the condenser  train for 
the Bio-oils, which is ready to go.
 
I will keep you updated.

Folke, 

Thank  you for an excellent description. Since 1990 there has been work in 
Japan on  charring sewage sludge which so far has not turned up toxic 
concentrations of  pollutants such as heavy metals in the low temperature char.   
We  see the same mechanisms of Phosphorous concentration in the concentrated  
animal feed operations, or CAFOS. We developed a method of burning poultry  
litter to recover phosphorous-rich ash for feed and potassium-rich ash for  
fertilizer. Charring litter may make more sense. So far we have seen no  results 
from the much advertized poultry  litter pyrolysis projects in  Virginia and 
elsewhere.
