TOILETS:
THE FUTURE OF
SUSTAINABLE
SANITATION
CompostEra
The Vision of Sanitation in India is about health,
dignity and safety for women and children
No more
children
dying
daily
from
diarrheal
diseases
It is high time that the needs of the most vulnerable set the bench
mark for one of the most crucial health and safety issues!
SHOULD THE VILLAGE TOILET LOOK
Like this ? Or like this ?
DO IT RIGHT the FIRST TIME
Yes India needs toilets … but toilets that users
want to use: toilets that DO protect health and the
environment, encourage personal hygiene, can
contribute to agriculture, are easy to build and not
be dependent on frequent maintenance, work
equally well as sit-down and squat-design, and are
attractive enough for people to welcome them into
the heart of a village, which brings the only crucial
safety to women and children from attacks.
Examples of successful investments
The unique expertise of our group is to
make toilets that are attractive
1. to users at a reasonable cost,
2. to the service and cleaning crew
3. yet be very cost-effective.
Fact: Initial marginally higher costs
than toilets that pollute ground water
and are repulsive to users … liked
toilets do not deteriorate nearly as fast
as the ugly mediocre ones ...
CompostEra Long Term Processing Toilets.
IMPORTANT FEATURES
Attractive to users at a low cost
Works on solar as well as grid power
No odor and therefore not attracting disease
carrying insects … odor and flies are the
prime reasons why people want flush toilets.
CompostEra Long Term Processing Toilets.
The liquid end product is a bacteria-free fertilizer
The essential nutrients comes from urine, not
from feces
Feces carries almost all of the disease causing
organisms … in CompostEra they are contained
and rendered harmless for up to 40 years.
Long-Term Processing Equipment
Key Advantages:
Simple odor-free, no-flush toilet
technology for on-site processing
Urine and water (for anal
washing) is filtered inside the bio-
digester resulting in a safe-to-use
fertilizer
The aerobic decomposition
results in no-odour outside the
building either. Therefore it can
be placed at the heart of any
community village or inside
homes
Benefits of Long Term Processing Toilets
For the Environment:
Safely contains the feces and pathogens for up to 40 years !
Yields a clean, odor-free, and safe-to-use, concentrated LIQUID
fertilizer that puts nutrients safely back into the soil
Saves the drinking water that flushing toilets would destroy
Makes no sewage no discharge no pollution !
Why don’t we make all toilets like that ? … we could !
90% of the cost of waste handling is transportation cost …on-site
treatment saves a lot of money and energy
In India, which houses 15% of the world’s population but has only
4% of the world’s drinking water, a toilet that saves water is a huge
asset.
User benefits of on-site processing toilets
For the User:
No water is used for flushing the toilets (the WC flush
does not really clean the toilet – it is just the transport)
Always odor-Free … when you come, when using it, no
odor left behind … flush-toilets do leave odor !
Comfortable to use … use and leave without worries!
Benefits of Long-Term Processing
For managers:
3d world toilets must NOT require service and
maintenance [other than cleaning the
bathroom] … because it won’t happen for the
most part but also because “servicing” is too
open for different interpretation.
These toilets are designed to “use and leave”.
Cost effective … flush installations are 3-5
times more expensive
They contain the shrinking feces for 40 years
They isolate virus, bacteria, parasites, prions
and most metabolic residue of medicines.
Works in any climate and geographical area.
• Installations outside India
• Installations within India

Pilot projects in India since 2010
Project name: Pilot project to introduce and adapt enclosed long-
term composting for India
Location: Mohaddipur Hamlet, Nalanda District, Bihar, India
Partner: Water, Sanitation and Hygiene Institute (WASHi), India
Technology – Swedish Enviroment Institute , Compostera
Funding from SEI, SIDA [Swedish Int. Development Agency]
A collection tank for the
liquid fertilizer known as
“fertila” (treated urine
and washing water) can be found
outside the processing chamber of the
sanitation and hygiene complex.
Bihar … more women’s toilets needed !
A Way Forward
Households
Schools
Highways
Public toilets
Any large gathering
Emergency toilets (refugee camps, earth quakes)
Use anywhere: all climate zones: deserts, mountains,
permafrost, Dead Sea level … Quick to build on site after
