Biological toilets to be set up in Lakshwadeep Islands

Lakshwadeep Islands will be the first to have biological toilets.



New Delhi: Environmentally sensitive region
of Lakshwadeep Islands will be the first to have biological
toilets in the country for eco-friendly disposal of human
waste.

The Lakshwadeep government has asked the Defence Research
and Development Organisation (DRDO) to install 21 biological
toilets in Kavaratti and other islands.

"Biological toilets use a bacteria called psychrophilic
found in Antartica region. The bacteria thrives on these waste
and delivers a residue that is odourless, non-pathogenic and
has no toxicity, thus making it eco-friendly," R B Srivastava,
Director, Life Sciences, DRDO said.

"The surface water-level in Lakshwadeep Islands is one
metre deep and as such sewage waste gets mixed with it. The
Planning Comission was looking for a solution. This technology
will help avoid this contamination," he said.
Human waste disposal, especially in moving rail coaches,
is a burning problem. If not properly disposed, it can result
in spread of water-borne diseases like typhoid, cholera,
dysentery and diarrhea.

"Ministry of Rural Development has shown interest in this
technology and Ministry of Railways has signed an MOU with us.
They have asked us to make certain changes because other waste
material like bottles etc are also disposed off in toilets of
rail coaches," Srivastava said.

The problem is more severe in glaciers where low
temperature delays natural bio-degradation of the waste and
sunlight exposes the waste buried in the ice, causing foul
smell.
"The melting ice takes the waste to rivers disturbing the
aquatic eco system," he said, adding biological toilets was
suitable for such areas as it treats human waste in a method
that is odour less and free from pathogens and environmentally
acceptable.
