India’s Defence Research and
Development Organization (DRDO) have invented Bio - Digester Technology as a
solution to prevailing unhygienic sanitation methods. Bio Toilet Technology facilitates termination
to residual human excretory waste. Human
waste is decomposed by special lab mutated bacteria into water and bio gas. The Bio-digester toilet is total
maintenance-free system, which does not require any sewage system. The
inoculums bacteria used in these bio-digester toilets procreate and generate
new bacteria in an anaerobic environment without the need for repeat dosing. The bacterial consortium degrades night
soil to produce colorless, odorless and inflammable gas containing 50 – 70%
methane.
How
It Works: A group of lab mutated bacteria decomposes the excretory waste
through microbial reaction. Bio-digesters have 3 anaerobic chambers that treat
Human wastes effectively, and don’t require any cleaning or emptying the tank
because of its unique systematic structural arrangements. The treatment, the task of cleansing water is
continuously carried forward from the start to the end point, till the water
exits the bio-digester. When the treated
water finally comes out it is 98% clean and free from entire pathogens.
The breakthrough technology has
potential in the urban slums since the safe disposable of human waste is a
major challenge. The bio-digester
technology has been successfully implemented in public toilets across
India. SPARC hopes to introduce this
technology to the Mahila Milan and to explore the possibility of implementing
the system within the slum.
