This poster is about the possible uses of Water Hyacinth as a renewable energy source to serve as a solution in the existing energy crisis in 3rd-World countries.

1. As Chemical Engineers of 21st century, we
are facing two daunting challenges namely,
Environmental Waste Management and
Energy Crisis. As time goes by our natural
resources are decreasing and finding newer
sources of energy is becoming our prime
concern. On the other hand a lot of weeds
and harmful plants marked as environmental
waste are causing a lot disturbance in the
ecological balance. Here, we are converting
Water Hyacinth (an environmental waste) into
renewable energy meeting both the
challenges simultaneously.

Water hyacinth is an
aquatic plant with a
very high growth rate
which removes
nutrient elements
from water, outbreaks
covering water
surfaces and
consumes most of the
dissolved oxygen
leaving little for fish
and other aquatic
species, which die off
as a result. Renewable
energy is energy
which comes from
natural resources
such as sunlight,
wind, rain, tides, and
geothermal heat,
which are renewable.
To produce Methane using Water Hyacinth the
following are required:
 Digestion tanks
 Shredders
 Gas holders
Pipes and other fittings
A supply of animal manure
The installation is made up of six
discontinuous-type digesters, made of reinforced
concrete, provide the environment essential for
the bacterial activity that produces the biogas.
Fresh water hyacinth is feed into the digester and
animal waste of optimum proportion follows and
then the fermentation takes place slowly.
Produced Methane gas is collected and converted
into electricity using a power generator.
BIOGAS PLANT
USING WATER
HYACINTH
Water Hyacinth is removed to
produce Methane in this process, so
river, pond and lakes can maintain an
auspicious environment.
Electricity problem in the rural areas
can be solved by converting biogas
into electricity, then it can be used
for:
1. Lighting, Heating and
Cooking
2. Irrigation and Threshing
3. Lifting and Pumping of
portable water
4. Feed Processing etc.
Electricity
Consumption
per day
360 Unit
Required Methane 30.86 M3
Required Water Hyacinth 3.09 Ton
Cost of Electricity per unit Tk.2.14
NB: Water area of 100 decimal required.
NB: Cost of Electricity per unit Tk.3.95 (REB)
Following Facts must be
considered during Methane
Production:
•Digesters must be dis-
continuous and fixed dome type.
•Addition of cow dung will
increase production
•Water Hyacinth should be dried
and cut into small pieces.

This indicates that large scale
implementation of Water
Hyacinth-Biogas Project is fairly
feasible.

Water Hyacinth-Biogas Project is
an exceptionally prolific project
which not only manages an
environment threat but also
produces methane gas, can be a
great solution of electricity
crisis in the rural areas of
Bangladesh. Being a remarkable
breakthrough in the field of
waste management and
recycling, if given priority it will
obviously proof its worth.
