Biodigester Toilet / Latrine System
Bio-Digester Toilet is a decomposition toilet system by means of which the sludge(Human Waste), the fecal matter, is decomposed to bits in the digester tank using a specific high graded bio-catalyst further converting them into methane and water, discharged further to the desired surface where they can be used. The Bio-digester toilet is total maintenance-free system & does not require any sewage system.
Feacal degradation occurs through catalytic reactions which converts it into biogas. The smell of feacal matter, the disease causing organisms in the feaces and the solid matter are almost eliminated. On dry weight basis, 90% of the solid waste is reduced. The gaseous effluent (bio-gas) is continuously let off to the atmosphere. Biogas can be used for various energy incentive activities like cooking water and room heating. Liquid effluent can be drained to any surface or soak pit without any environmental hazards.
A catalyst has been formulated and adopted to work at temp as low as 5 Co. This is the component which acts as seed material to the bio digester and converts the organic waste into methane and carbon-dioxide. Bio-digester serves as reaction vessel for bio machination and provides the conditions and required temp for the reaction. The optimum temp is maintained by catalytic heat, insulation of the reactor and solar heating.
The following are the various kinds of biodigester toilets and their target groups;
Domestic Bio-Toilet
Plain Institutional
solar Bio-Toilet
Bio-gas generator bio-toilet

Domestic Bio-Toilet
Kenya’s slum and majority of rural population defecates in the open and this can aptly be called the "big open toilet of Kenya". Few toilets in the urban slum and rural areas are connected to the sewerage system; sewage from the rest flows in open drains, causing contamination of ground as well as river water, as per 2009 Census. This has serious health implications and is consequently a big economic burden.
Time has come to use technology and advances in biological sciences to tackle this problem;
Bio-Digester Toilet System, based on catalytic biodegradation of organic waste was conceived and initially developed for defense forces deployed at high altitudes areas. In this system, fecal matter is decomposed to bits and converted into water and little of carbon dioxide & methane gas. It is totally maintenance-free system and does not require any sewerage system.
Maintenance of bio toilet; The components of bio toilet are; toilet seat; the drain pipe from the toilet connected to the bio-digester, the bio-digester itself, the catalysts and the outlets of gas and liquid effluent. All of them should be maintained and should be in working condition.
- After using the toilet the man should pour 1 liter (4 Mugs) of water.
- Bio- toilet can be used conveniently by 50-60 persons every day.
- Keep the toilet clean.
To check the proper functioning of bio-digester;Close the outlet valve for 24 hours, open it then, take the burning match stick close to the out let valve, the gas will burn and this indicates that the bio digester is Functioning well.
Don’ts; Do not throw Kerosene, Soap, Plastics, Bottle, Tin Cans, and antiseptics inside the toilet Seat AND Do not let the gas out let valve close.
Benefits of Residential Bio-Digester Toilets
- Compact in size
- Quick installation
- Zero maintenance
- No residual solids waste
- No Pathogens
- No foul smell
- Only water discharge
- No need for big Sewage treatment plants
- Mitigates pollution of underground and river water
