Of historical interest the cobs, like oat hulls, were hydrolyzed to extract furfural. The residue was carbon rich material that made a very good fuel. It was a short step from there to activated carbon. The last of the furfural production in Iowa was in about 2004. Today the furfural production is all in China. So we don’t have an easy carbon byproduct from extracting chemicals from these residues. The cobs go to ethanol plants and the oat hulls go into a university boiler where they are co-fired with coal. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Tom <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Stoves [mailto:stoves-bounces@lists.bioenergylists.org] <b>On Behalf Of </b>Ronal W.

I am getting less certain with time on the availability of corn cobs. Must have a lot of regional variability.

We have used corn cobs with great success in the TLUD style Estufa Finca stoves. I love showing people our little tiny corn cob charcoal. We have also successfully made a lot of biochar from dried corn stover in our version of the 55-gal drum TLUd style J-Ros. MIT has also promoted both of these approaches in it's Field-to-fuel program in Haiti and Nicaragua.<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>But there is a problem with thinking of corn cobs as a stove fuel: most cobs are used as animal feed (pigs/chickens) and needed for it. Applying a hierarchy or best use: the pigs win!
