Coffee Pulp/Cherry<BR></FONT><BR></DIV>
<DIV></DIV>Frank,<BR><BR>Here in Vietnam we have both dry coffee husks and wet
coffee pulp.<BR>We gasify the dry coffee husk as a source of fuel for drying the
coffee bean from a wet mill,<BR> and that we ferment the wet coffee pulp as
a feed for pigs.<BR>The fermented coffee pulp has a crude protein content as
high as 14%.<BR><BR>Wet coffee pulp is an extremely low-grade fuel, but it can
be easily converted into a quality pig feed.<BR>All that is needed to ferment it
is to add 5% molasses by weight and put it into a sealed container or
bag.<BR>The pH of this fermented brew drops below 4.0.<BR>After one week it can
be fed to pigs.<BR><BR>Some types of waste earn more money as a
fuel,<BR> and some types of waste earn more money as a feed.<BR>From an
economic point of view, it's far from ideal to burn pig
feed.<BR><BR>Thanks.<BR>Paul<BR><BR></BODY></HTML>
