<DIV><FONT face=Arial size=2>Friends,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am currently managing the greenhouse gas
emissions inventory for the industrial sector in Honduras, Central America.
Looking at the IPCC's technical guidelines (1996) the Honduran working group is
using, I note the emissions associated with the food and beverages industries
are NMVOCs only. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>A little sidenote states that Carbon Dioxide needs
not be taken into account because such emissions pertain to the 'utilization of
biological carbon'. Can someone further explain this to me? What happens with
the CO2 emmited in the fermentation processes as the producion of beer and
spirited drinks and the leavening of bread?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In the alcoholic fermentation, one glucose molecule
(C6) would go to yield two ethanol (C2) and two Carbon Dioxide (C1) molecules,
of which the latter is a gaseous emission. C in glucose and ethanol is
'captured'; C in Carbon Dioxide is atmospheric gas (unless, of course, captured
and retained as such, which to a point, the fermentation industry does).
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I yet don't understand why these emissions are
regarded as utilization of biological carbon. Is the assumption that
C in emitted fermentation CO2 is then captured in vegetable material synthesis
that yields the crop that contains the glucose? </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If so, how are we sure of the balances? For a
specific country, wouldn´t it be safest to take into account these emissions and
then deduct them from overall C capture?</FONT></DIV>

<DIV><FONT face=Arial size=2>Thanks for your insights. </FONT></DIV>
