Hello Edward,

There  is  an SNV biogas project in Indonesia. The
Senior  Biogas  Advisor  is:  Sundar Bajgain, Tel:
+62-21-7892489/78837577  HP:  +62-(0)  82112373615
e-mail: <sbajgain at snvworld.org>  
http://www.snvworld.org/indonesia.  He  has  built
up   good  experience  in Nepal and  Bangladesh on
biogas programmes.

1. There  are  arguments  on how worse methane is for
the  atmosphere  than carbon dioxide, depending on
assumptions   on   how   long   it  lasts  in  the
atmosphere.   Global  warming  is  the  result  of
radiation  at different frequencies being absorbed
by the different gases, preventing heat being lost
from  the  earth.  Methane  absorbs more radiation
from the infra-red spectrum than carbon dioxide.

2.  There are two ways in which biogas can be used
in  engines:  a  dual-fuel  engine  uses diesel or
biodiesel to provide ignition (about 20% or less).
Raw  biogas  can  be  used in these engines, mixed
with  the  air intake. A spark ignition engine can
also  be  used  with  biogas,  but these are more
susceptible  to  corrosion from hydrogen sulphide,
so this should be cleaned from the gas.

3. Oil cake is a good feed for a biogas plant, but
should  be mixed with other materials. A colleague
in  India  has  built a plant for a community that
uses  cattle  dung   and   oil  cake  as  the main
feeds and works well.
