<p class=MsoNormal>I am Mr Danesh Kumar from India, I have been in the field of
promoting biogas technology at Grass Root level, I have been building biogas
plants for family size , the building material from bricks and concerte, has
been, changed to ferrocement, lesser volume of materials, but need highly
skilled mason to complete.<br>
<br>
I have been toying with idea of using biomass directly, my previous experience
has been with batch fed system, using simple technologies- plastics for lining
the pit and nylon based polymers for collection of gas, it was useful to
understand the whole concept, found the gas production was high, means you get
about 30-40% of the gas produced within a month, hence it will not be useful
for a small sieze family, but use ful to meet the enrgy needs of certain
operations- like threshing or irrigation, approximately 1000 Kgs of dry biomass
produces about 280-320 CuM of gas.  The certain problems have cropped up,
more with removing of the material after decomposting, the gas produced in the
system, have low pressure, thus it is difficult to use in ordinary biogas
stove, but can be stored, as use a supplemetary fuel for running diesel engines<br>
<br>
Currently I am working on a new system evloved and developed from Indian
Institute of Science, bangalore, it is called Plugflow biogas digester, it can
take a biomass (soft)- leaves, leftover of crops, kitchen and food waste, in it
is native state, it needs no refilling of water, about 20 Kgs of green of 6 Kg
of dry biomass can meet the need of small size family, producing about 1.75 CuM
of gas, the only draw back, what goes into the system, must be pulled out manually,
otherwise it is good system, even if you donot recharge a for couple of weeks,
you make it function within a week back <br>
<br>
Have been trying to improve the methane content of the gas, by using Oil seed
cakes, and also with small doses of trace elements, to speedup the anaerobic
digestion<br>
<br>
the left over materiel, is soft can be further composted and used as manure for
improving the soil organic carbon, the liquid can be collected<br>
<br>
any one having questions, can get back to me, on this platform<br>
