Dear sir,
I meant how the chemical process or biological process can convert COD
to be Bio gas detail? At least from theory

Dear Mr. Silalahi,
it is not possible to predict the quantity of biogas from COD, as the
biogas digester cannot digest all the organic matter.
Yours

Hi everyone,
I am glad to announce to this mailing list the 5th conference of
RedBioLAC
(Red de biodigestores para America Latina y el Caribe), the Latin
American
and Caribbean Network for Biodigesters.
Our past conferences had focused on domestic biogas research and
experiences; this year we will be offering a biogas course, a field
visit
within the Zamorano University (Honduras) and a conference. The main
objective of this meeting is to get to know the latest developments in
the
field of ?100m3 biodigesters in the region in order to disseminate more
and
better systems at competitive prices. We will focus on the use of
biodigesters to process livestock waste, power agroindustry and treat
wastewater in order to reduce reliance on fossil fuels, diminish GHG and
providing a proper disposal for organic wastes.
We will be having stands for organizations or biogas product providers
who
would like to showcase their products or services.
Please find attached the conference announcement in Spanish. For
registration please go to

I would appreciate if you forward this information to people who might
be
interested in attending this conference,
