India's 300 million cattle. Biogas technology may have the potential to
short-circuit the 'energy transition' Leach (1987) describes from biomass to
'modern' fuels.
·
The enormous
potential of
biogas, estimated at 17,000 MW
·
The gas is useful as a fuel substitute
·
Biogas systems
also
provide a residue organic waste, after anaerobic digestion that has superior
nutrient qualities over the usual organic fertilizer.
·
Function as
a waste
disposal system, particularly for human waste,
·
Prevent potential sources of environmental contamination.
·
Provision of power for a rural-based industry
·
Biogas may also provide the user with income generating
opportunities
·
By providing
an
alternative source of fuel, biogas can replace the traditional biomass based
fuels,
·
What is more
certain, is
the impact on rural women’s' lives.
·
A clean and particulate-free source of energy also reduces the
likelihood of chronic diseases
·
Significant reductions in emissions associated with the combustion
of bio fuels, The use of biogas systems in an agrarian community can increase
agricultural productivity
Some of the key expected
benefits of an anaerobic digester are:
- Odor control
- Renewable energy production
- Pathogen reduction
- Greenhouse gas reduction
- Reduction in total oxygen demand of the treated manure (total
oxygen demand is a measure of potential impact on aquatic systems)
