[Terrapreta] Overview on biochar production methods

[Robert Flanagan]

Hi All,

Another company in India that have successful biomass to energy projects
goings for over 20yrs is http://www.ankurscientific.com/whygasification.htm for
a look at feedstock's and solutions take a look at their range
http://www.ankurscientific.com/range.htm . Ankur already have off the shelf
charcoal producing gasifiers suitable for both forest and agricultural
waste. They also have a new anaerobic digestion process for methane
production for details contact gpnagori at ankurscientific.com .



Regards,
Rob.
