There are regular waste disposal problems in almost
all Institutions like hostels, hospitals, convents, old age-homes, etc where
more peoples are staying together. In the same time the cooking fuel
consumption of these Institutions is also very high. Fairly large quantities
of firewood and other cooking fuels are consumed for routine cooking
purposes. HOLLANDIA BIOTECH is keen to educate these institutions about the
advantage of using non-conventional energy sources. Most of these
institutions rear cattle, the dung of which can also be utilized as a feed
material to the biogas plant. The biogas generated will sufficiently reduce
the regular consumption of other cooking fuels like firewood and LPG.
For the effective operation of a bio waste treatment plant, electricity is
quite essential. The main advantage of waste to electricity project is that
no external power is required for the operation of the plant. The power
generated in the treatment plant can be utilized to meet the in-house
requirement completely. Excess quantity can be utilized for any type of
off-grid application, such as street lighting.
The generation of electricity through conventional method is a costly
affair. Severe environmental problems will be caused on account of
electricity generation through coal, diesel etc. Even in the case of hydro
electric projects, many environmental problems will arise in and around
project area through deforestation.
The generation of electricity using biowaste treatment plant is not a
costly concern. Of course the installation cost of a Waste to Electricity
Project may be a little high. But the recurring expenses will not be
substantial for the operation of the plant. In the plant, biogas is being
generated everyday through anaerobic decomposition of waste.
Normally 1.5 kilo watt electricity can be produced from One cubic metre
biogas. Depending upon the percentage of methane content in biogas, the
power generation may slightly vary. The size of the generator can be fixed
depending upon the availability of gas and quantity and duration for the
requirement of the power. The gas can be utilized as operation fuel in
gensets. Before feeding biogas as fuel in gensets the gas has to be passed
through a gas scrubber to remove unwanted particles, gases, moisture etc.
There are two types of generators used to generate electricity from biogas.
One is the duel fuel model and the other is 100% biogas model. Duel fuel
models are diesel gensets. In this system the biogas is connected to the
generator through air mix. Once the biogas is passed through the gensets,
automatically consumption requirement of the diesel is reduced. Normally
duel fuel gensets are working in 80% - 20% mode.
In 100% biogas engines, no other fuel is required either for starting or
for operation. Any type of petrol engine can be modified for operating the
same using biogas as operation fuel. The imported models of 100% biogas
engines are very costly ones and the maintenance of such systems is very
expensive. HOLLANDIA BIOTECH has developed 100% biogas engines. These
engines are installed in various projects and the performance of all of them
is very good.
