One TLUD residential cookstove produces about 1 kg of good char per
day, or 365 kg per year. Three families would make 1 ton of char
per year.<br>
<br>
TLUD stoves appropriate for this can be purchased for $18 to $30
each (delivered, retail cost). So for 3 stoves, call that $60 to
$100 of stoves per ton / yr, with good life span (5 yrs?) and low
mantenance. <br>
<br>
So, $100 times 5000 ton of desired output would cost $500,000 for
15,000 stoves. That is 1/6th of the 3 million dollars mentioned.<br>
<br>
I am working on a report from the Servals stove project in the
Ganges delta with 11,000 installed stoves, and growing. And it did
not cost even half of that sum because of other factors. <br>
<br>
Stay tuned. Academic results take some time to get released. But
it all looks promissing. (I hope I have my numbers all correct.)<br>
<br>
Oh, by the way, the issues of fuel supply, fuel transport costs, and
operational labor (cooks) and even char collection costs all make
the numbers look even more favorable. <br>
<br>
It would sure be nice and would be appropriate is someone with the
million dollar budgets for char production would become more
interested in the TLUD approach. Oh, the money-managers want to
know the return on investment. Sorry, most of the benefits (both
financial and social) go to the impoverished people who can barely
scrape together the $15 to $30 to get the stove. But you can still
get the char at a very low price and then make money off of that.<br>

<p class="MsoNormal"><span style="color:#0432ff">In my
experience, the “black box” technology to produce
biochar on an industrial scale is often in the range
of $500K to $1M. However, that often only represents
about 10% to 20% of the total project cost, which
includes, building, services, product packaging,
storage and shipping, biomass handling and processing,
environmental controls… I actually found the $3M
price tag to be at the lower end. I would have
thought that an average plant would be $5M to $8M for
a 5000 ton per year facility.<u></u><u></u></span></p>
