a. Low-Cost Biogas Plant
The GGC-concrete model biogas plant, which has been popularized since more than 2 decades in Nepal is
costly to an average farmer. Deenbandbu model biogas plan, which proved to be low cost biogas plant in
India were experimented in Nepal but it could not be popularized in Nepal. Therefore, it has been imperative
to evolve low-cost biogas plant that is affordable to the average farmer.
h. Cold Weather Biogas Plant
Production of biogas is significantly affected due to drop of temperature. Thus, until now, this technology has
been of little use in the higher altitude or cold climate. Therefore, research work needs to be initiated in view
of increasing the efficiency of gas at the cold climate or in higher altitudes.
c. Use of Biogas Slurry as Feed and Fertilizer
So far, biogas users have been paying attention only towards the utilization of gas and they have been
neglecting the use of digested effluent as fertilizer. As chemical fertilizer is costly, imported and is not
available on time, proper utilization of this locally available resource should be given top-priority. The
farmers have to be convinced about the use of slurry by conducting appropriate research and field
experimentation. Similarly, possibility of utilizing bio-slurry as feed and food for animals, poultry birds and
fish needs to be explored.
d. Alternative Feedstock for Biogas Production
Until this date, it is mostly cattle and buffalo dung that are used commonly for biogas production in the rural
community. In order to increase the scope of biogas production, it is advisable to use various other local
alternative feed stocks for biogas generation. For example, biogas can profitably be produced from the
obnoxious weeds such as Banmara (Eupatorium Adenophorum) and Water Hyacinth.
e. Production of Biogas from Municipal Solid Waste
Municipal solid waste if disposed improperly can create problems due to pollution and as such could be
detrimental to human health. But on the other hand, some countries have already benefited by processing the
MSW into anaerobic reactors in view of production of energy and bio-fertilizer. In the context of Nepal, it is
worth to carry out pilot programme in this subject.
13.4 CALENDAR OF TWENTY YEARS'S PERSPECTIVE PROGRAMME (2000 TO 2020) IN
NEPAL
20 years' perspective plan has been elaborated in Annex I of this publication.
13.5 LONG-TERM GOVERNMENT POLICY
Considering the popularity of biogas plants, its huge potentiality and its benefits, the present subsidy policy is
likely to be continued with the support of other donors and potential investors, even after the closing of
present biogas support programme being implemented as a joint venture of HMG, KfW and SNV. The
present subsidy policy is limited to less than 10 m 3 plants of family size. However, the Government of Nepal
has a provision for feasibility study of community biogas plants based upon biomass products and solid waste
beside cow dung with the objective of supplying gas and electricity to neighbouring areas (AEPC. 2000).
13.5.1 Objectives of Tenth Plan
■
■
Helping increase the consuming capacity of rural families by developing and extending
the alternative energy as a powerful tool in poverty alleviation.
Supplying energy for commercialization of domestic needs and the profession of the rural people by
developing alternative energy technologies based on the local resources and tools.
