<P class=MsoNormal>I am currently doing a report on approximately 20 small
scale UK farm digesters, looking at various parameters and what makes a
successful digester installation. Current 'industry' thinking is that
digesters at this scale are not economically viable. However, the
smallest of these has been running successfully for 20 years on an organic
farm with 65 cows, saving thousands by using the gas to heat the house and
diary washings. The average Uk dairy herd is about 112 cows.
Another one here has been running for more than 20 years, heating a very
large manor house. Another interesting digester running for more than two
years digesting slurry from cows bedded on woodchip and sand,, as well as
chicken muck. It has an automatic degritting system and the digester does not
have to be stopped. <o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p> </o:p></P></DIV>
<DIV>
<P class=MsoNormal>At this scale, the reason for the success of these systems
are that they separate the digestate which comes out of the digester, they use
inexpensive and easily maintained gas mixing which means a low parasitic load
(one is as little as 1watt/cubic meter), the loading is typically simple auger
or gravity feed straight into the digester, the control system is very simple
and the digester is integrated into the farmyard. Suitable cast iron boilers
have lasted for 20 years and are still running. <o:p></o:p></P></DIV>

send a link/copy when it is published. <o:p></o:p></P></DIV>

<P class=MsoNormal>Charles-<BR>There's at least one small-scale digester of
that size currently operating in the U.S. - at the USDA Beltsville
Agricultural Research Center in Beltsville, MD. The dairy's herd size
is roughly 125-130, with ~100 milking and producing manure at any given time
(dry cattle are let out to pasture). The digester was built in 1994
and was constructed as a continuous stirred-tank reactor. I have
tentative plans to conduct research on this digester simultaneously with a
low-cost, pilot-scale digester project operating on the same waste-stream
that's being constructed by our lab group at the University of
Maryland. I don't have intimate knowledge of the USDA CSTR's history,
but I can tell you what I know.<BR><BR>The digester was originally
constructed for odor control as an upright, cylindrical concrete tank (I'm
not sure enough of the designed HRT to give you information on it), and was
later insulated with gunnite-coated styrofoam. It operates on
mechanically screw-press separated, scraped waste, and utilizes the biogas
produced to power a boiler that circulates hot water through a conveyance
system installed within the digester for heating; a combined heat and
power electric generator was installed in the mid-2000s, but it has never
been brought online. The digester's had a number of problems come up,
including repeated clogging of the supply lines (originally 3-4" ID, now
6"), the break down of the screw-press separator and supply pumps, and the
corrosion of the boiler due to inadequate scrubbing. To be fair, many
of the problems associated with the digester are the result of fluctuating
research interest, funds, management, and the lack of an effective biogas
scrubbing system, but they exist all the same. Currently, the digester
is up and operating... although obviously not ideally.<BR><BR>Although most
of the digestion systems are covered lagoons, the <A
href="http://epa.gov/agstar/projects/index.html">AgSTAR website</A> contains
a link to a Excel file detailing the digesters currently registered in the
EPA's system (look under "Farm Project Profiles"). A few of them
approximate the herd numbers you're interested in.<BR><BR>As a side note,
our research at the University of Maryland, together with research at Ohio
State and the University of Wisconsin, is attempting to introduce
smaller-scale, lower-cost systems in the U.S. I gave a presentation in
October on small-scale digestion and some of the current efforts that you

small farms with digesters in the United States? When I say small farm I
don’t mean 2-3 cows, I mean a farm with around 125 dairy cows, which is the
average herd size in Michigan. If so, where are they and what has been their
experience with their digester? I suspect there probably are no small farms
with digesters in the US, but I would really like to know. I have had
numerous inquiries from farmers with small farms in West Michigan about
putting in a digester on their farm. If my assumption is correct that there
are no small farms with digesters, are there farms with comparable numbers
of dairy cattle with digesters outside of the United State? If so, where are
they and what has their experience been with their digester?<o:p></o:p></P>

<P style="TEXT-INDENT: -0.25in" class=MsoListParagraph>1.<SPAN
style="FONT-SIZE: 7pt"> </SPAN>Are there
small farms with digesters in the United States? When I say small farm I
don’t mean 2-3 cows, I mean a farm with around 125 dairy cows, which is the
average herd size in Michigan. If so, where are they and what has been their
experience with their digester? I suspect there probably are no small farms
with digesters in the US, but I would really like to know. I have had
numerous inquiries from farmers with small farms in West Michigan about
putting in a digester on their farm. If my assumption is correct that there
are no small farms with digesters, are there farms with comparable numbers
of dairy cattle with digesters outside of the United State? If so, where are
they and what has their experience been with their digester?<o:p></o:p></P>
