Charles and listers,<br>
<br>
The best source of information on AD in USA is the AgSTAR project
run by EPA (<a href="http://www.epa.gov/agstar/">www.epa.gov/agstar/</a>).
They have a database of digesters, which includes a few small ones.
<br>
<br>
They point to the Minnesota Project (<a
href="http://www.mnproject.org/index.html">www.mnproject.org</a>)
which is trying to concentrate on biogas for small farms (125 cattle
or less).<br>

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>
