<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The “corn cob as TLUD fuel (in Kenya)” topic clearly needs more information. Reading between the lines in the article and messages:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">1. 60 K tonne of cobs per year would be 5 K tonne per month or 1,250 tonnes per week (ignoring the seasonality of corn harvesting). They are getting it from somewhere.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">2. Factory “appears to be closing down” (please confirm), but it only started operations in Oct 2017, but it was “purchased [from the former] Kenya Furfural Company plant from its receiver managers Ernst & Young..” Seems to have a troubled
history.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">3. But this area (around Eldoret, Kenya) would seem to be a great place to have a TLUD stove project (and industry) with maize cobs as the abundant fuel.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But projects require having competent people on the ground and in charge. And a sponsor to get things rolling. There are at least two sources of TLUD stoves. The closest is Maurice Onyango in Bungoma (who is receiving a copy of this
message.)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And back to the main question: What is the key to having such abundant corn cobs? Only answer suggested thus far is commercial maize farming. Apparently with harvesting of whole ears (not shelling in combines in the fields and throwing
away the cobs). Is this not occurring elsewhere? <o:p></o:p></p>

Kevin McLean and I have been supporting some research in Uganda on making char from corn cobs. They seem perfect to me - the right costs, shape, and size. Mostly left in the field, but would be much more valuable if converted to both energy and char
(the latter to go back to the field). <br>
<br>
Anyone know of any place where this is now happening - in stoves (TLUD or other)?<br>
<br>
This is somewhat similar to using rice husks, which is happening a lot. Besides corn cobs, what other crop residues should be used for combined cooking and char-making? <br>
