ADVANTAGES OF AEROBIC BIOLOGICAL
OVER ANAEROBIC BIOLOGICAL TOILETS :
S.
Aerobic Bio Toilets
Anaerobic Bio Toilets
1
It uses Aerobic bacteria for bio digestion process
which is freely available everywhere in nature
It uses Anaerobic bacteria for bio digestion process
which is available only in Antarctica
2
The digestion process does not generate methane
gas. So, it is environment friendly.
The digestion process generates large volumes of
hazardous, foul smelling and inflammable methane
gas, which is a green house gas. So, it is not
environment friendly.
3
The digestion of the human wastes starts in 3 hours
and is complete well within 24 hours. So, it is a fast
process and requires a small retention tank.
The digestion of the human wastes starts in 24 hours
and takes over 3 days to complete. So, it is a long
duration process and requires a large retention tank.
4
A small retention tank is required for digestion,
nearly half in size of the anaerobic tank, so it is not
an expensive process.
A large retention tank is required for digestion, so it
is an expensive process.
5
A small volume of bacteria is required (10 ml for 300
liter tank) for the bio digestion process.
A large volume of bacteria is required (100 liters for
300 liter tank) for the bio digestion process.
6
The bio media is stored in spore form in suspended
state, so the shelf life is 2 years and above.
The bio media is mixed with cow dung solution in a
vegetative state, so its shelf life is less than 6 months
STONE INDIA LIMITED
An eight decade old multi-product engineering company , has
developed BIOLOGICAL TOILET SYSTEM towards its
contribution to its corporate social responsibility, after serving the
Indian Railways for decades, and now leveraging its talented pool
of technical resources, creativity and innovation, to save the
planet with its green products. The R&D team has spent 35000
man hours in research to develop ENBIOLET™ by which human
waste is completely digested by the bio-media present in the biodigester tank and converted into non toxic water and gas, There is
no chance of solid waste being discharged to the ground. This will
revolutionise hygiene and sanitation in the country.
AEROBIC BIODEGRADATION
MYTHS
ACTUALS
Forced aeration/Agitation is essential
It does not requires any Forced aeration/ agitation as
natural draft aeration is sufficient.
Incomplete Aeration ( Partial aerobic
condition ) leads to foul smell
The waste is completely digested in presence of natural air
leaving traces of CO2 and neutral water
Cannot tolerate detergents/phenyl
Bacteria works even in presence of mild detergents and bio
degradable substances
Generates large amount of sludge
Multi strain bacteria eats Proteins, Cellulites, Carbohydrates
Fats and others resulting in complete digestion leaving
behind only traces of CO2 and neutral water
Repeated addition of
bacteria/enzyme is required for the
process
Being in spore form it has a shelf life of 3 to 4 years and is
also fortified by enzymes. So the bacteria is long lasting
and does not need repeated charging as long as optimum
interval of defecation is maintained
Maintenance and recurring cost is
high
Only periodic toilet pan cleaning has to be done as
required, and no special maintenance is required on
account of Aerobic Biological toilets

ANAEROBIC BIODEGRADATION
MYTHS
ACTUALS
Works even in sub zero
conditions
No toilet can operate in sub zero conditions as in subzero the
water freezes and bacteria becomes dead or dormant. So a water
heater is required to keep the water from freezing in any case
A net surplus energy is
generated during anaerobic
treatment
The end product is Methane which is a green house gas and
causes global warming and cannot be discharged into the
environment
Can degrade
detergents/phenyl
Cannot tolerate strong detergents/phenyle as bacteria is affected
Generates very less amount
of sludge
Since the process of digestion is very slow and requires more than
24 hours for digestion, so in case of overuse incomplete digestion
results in generation of a large amount of foul smelling sludge
Onetime bacterial inoculation
is enough
Not true since the efficiency of the bio media deteriorates and life
does not exceed 6 months
Minimal Maintenance and no
recurring cost
No toilet in the world can sustain without regular cleaning of the
toilet pan & maintenance, so anaerobic bio toilets require
maintenance and recurring cost for cleaning just like any other
toilet, further as Methane gas is produced so continuous
deodorization and neutralization of discharge has to be done

USING INNOVATION FOR A CLEANER TOMORROW
USP
 Uses Aerobic bacteria for bio digestion process.
 Does not produce any greenhouse gases,
 It is a fast process (completes within 24 hrs) and
requires a small retention tank.
 The shelf life of bio-media is 2 years and above (stored
in spore form in suspended state);
 A small volume of bacteria is required (10 ml for 300
liter tank) for the bio digestion process.
 No septic Tank/Sewage line required
 Much smaller footprints

More than 3000 MT of human waste treated of which
otherwise would have clogged existing sewage
systems.
More than 60000 Liters of water conserved daily.
More than 30000 people using toilets for the first time.
Provided employment to more than 100 people.

4.
The Bio digester tank can be
placed on the ground, so no
digging or foundation required, so
installation is fast.
5.
Here the discharge is fully
digested non toxic, neutral water,
so the environment is not polluted.
6.
This system requires less
maintenance and does not require
periodic sludge removal as the
wastes are converted into water.
Septic tank requires excavation,
cementing, curing, partitioning, etc.
So, it is a labour intensive and time
consuming process and installation is
slow.
Here the untreated wastes seep into
the ground, which may result in ground
water contamination leading to an
epidemic.
This system requires periodic sludge
removal which may lead to waste
spillage on the ground resulting in
unhygienic conditions and diseases.
7.
The discharge water may be used
for irrigation in fields.
The discharge cannot be used for
irrigation in fields as it contains
pathogenic bacteria.
