    India army offers 'glacier toilet' in hi-tech sell-off

    Developed for troops serving on glaciers high in the Himalayas, the non-flushing "bio-digester" toilet made by India's top defence research body is now being offered to companies and poorer states.

    It is one of 200 technologies produced by the Defence Research and Development Organisation (DRDO) identified as for sale via the Federation of Indian Chambers of Commerce and Industry (FICCI).

    The national trade body and DRDO in October forged a four-year partnership to hawk dual-use military products as part of Premier Manmohan Singh's pledge in 2008 to offer defence technology spin-offs to the public, officials said.

    The "bio-digester" is among 10 of the DRDO products put on the fast-track for sale to state governments and private companies, an Indian defence ministry official added.

    "Our condition is to take any non-classified technology (that can be used) for the benefit of the common man," said Nirankar Saxena, Executive Director of FICCI's Centre for Technology Commercialisation, which heads the project.

    The "bio-digester" toilet conceived by a DRDO unit in the city of Gwalior, works by mixing self-multiplying bacteria with human waste in specially-made tanks, resulting in the production of methane gas and water.

    It was meant for Indian combat troops deployed on Siachen, a 6,300-metre-high (20,800-feet-high) glacier in disputed Kashmir where temperatures can fall up to to minus 50 degrees Celsius (minus 58 degrees Fahrenheit).

    Experts say they believe some 5,000 soldiers are deployed on the frigid wasteland, where calm has prevailed since a 2003 ceasefire with rival Pakistan.

    "Work on it began 15 years ago because excreta buried in snow by soldiers in the Siachen glacier polluted rivers when the ice melted," said scientist Vijay Veer of the Defence Research and Development Establishment, a DRDO unit.

    The bacteria used in the mountain version of the toilet were originally found in Antarctica, but another cocktail can be used in the hot tropical plains where the need for toilets in India is most acute.

    FICCI's Saxena said the Indian territory of Lakshadweep -- a cluster of islands -- has sought 12,000 bio-digesters at some 25,000 rupees ($550) a unit for a major housing project.

    Other DRDO products include heat shields for trains and vehicles, windows that control light penetration, mosquito repellents and medical kits to tackle dengue and chikungunya, both insect-borne viruses.

    They also plan to market a spray that guarantees to keep woollen clothes moth-free, affordable fire extinguishers and a body cream that keeps bed bugs away.

    The DRDO also has high hopes for its "Heat Stabilised Narrow Fabrics and Cordages for Improved Elastic Recovery Property" which military boffins believe could be used in bras.

    "The technology is a heat-stablised narrow fabric and the elastic in it is more robust than materials used in commercial brassieres," a DRDO official added.

    ficci thinks it is doing some favor to drdo by selling tis products. drdo should get into collaboration with other companies directly and get one time payment or continued royalty for its products

    Now this could end the continuous rants of Pakis and our chinese brothers about Sanitation condition in our rural areas ..!! :thumb:

    That's a good new for our ladies and bad for boys :rofl:

    Bio toilets don't come cheap!

    The methane should be burned to maintain temperature in the tanks. The reaction of the bacteria will not proceed at low temps in the glacier environment without external heat. It was not clear from the article that this is done. The idea of special bacteria from Antarctica seems bogus to me.

    It isn't bogus. The bacteria used have the ability to withstand prolonged severely freezing temperature and reactivate when thawed. You wouldn't want a porta-potty digester replenishment to be called from base when the toilet freezes over, would you :)

    BIO- DIGESTER (BIO TOILETS)


    Go Green Solutions with support of technology developed and approved by DRDO – Ministry of Defence offers an innovative technology for disposal of human waste in eco friendly manner. These Bio toilets can function at any atmospheric temp between -55 to 60 degree C. The bacterial consortium degrades night soil at temp as low as -55 degree C and produces colourless, odourless and inflammable bio gas containing 50 – 70% methane.

    [​IMG]

    The main constituents of Bio -Toilet are Pre fabricated above the ground shelter and Bio Digester tank. Bio digester tank is a cylindrical structure with the provision of inlet for human waste and out let for Bio gas. Temp in the bio – digester is maintained between 5-30 degree C. A person can use the toilet which is connected to the bio-digester. Night soil degradation occurs through microbial reaction which converts it into bio gas. The smell of night soil, the disease causing organisms in the night soil and the solid matter are eliminated totally. On dry weight basis 90% of the solid waste is reduced. The gaseous effluent (bio-gas) is continuously let off to the atmosphere. Bio Gas 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 with out any environmental hazards.

    TECHNOLOGY BEHIND BIO TOILET

    Human waste disposal in high altitude and low temp areas, Moving Railway coaches, Buses, Big Cities, Mines, remote areas, Beaches, Rural areas, long distance buses is a burning problem.
    The problem has further aggravated in glaciers where ambient temperature drops to -40 degree C and lower. The low temp stops/ delays the natural bio-degradation of the waste leading to its preservation (accumulation) for long time resulting in environmental hazard. Local heating by direct sunlight exposes the waste buried in the ice causing nuisance and foul smell. The melting ice takes the waste to rivers disturbing the aquatic eco system. More over human waste is also responsible for spreading of water born diseases like typhoid, cholera, Shigellosis, Amebic Dysenteries, Diarrhea etc.

    This technology is suitable for any area/ application in India. The process under this technology culminates in to treated effluent which is free from Pathogens and is also environmentally acceptable. The technology has major two components:



    • a- Low temp active inoculums
    • b- Temp controlled Bio digester
    A consortium of anaerobic bacteria has been formulated and adopted to work at temp as low as 5 degree C. This is the component which acts as inoculums (seed material) to the bio digester and converts the organic waste into methane and carbon-dioxide. The anaerobic process in- activates the pathogens responsible for water born diseases. Bio digester serves as reaction vessel for bio methanation and provides the anaerobic conditions and required temp for the bacteria. The optimum temp is maintained by microbial heat, insulation of the reactor and solar heating.


    DISTINCTIVE ADVANTAGES OF BIO-TOILETS


    • Disposes human waste in a 100 % ECO friendly manner.
    • Generates color less, odor less inflammable bio gas (can be used for cooking heating) and absolutely clear odor less water. Water is full of nutrients and minerals and is good for irrigation purpose of near by gardens, lawns etc.
    • Does not require any septic Tank, Sewage Tank connectivity.

    SALIENT FEATURES


    • Suitable for sub zero temperature of Himalayan Region, Glaciers, Railway coaches, Buses, Highways, Remote areas, sea ports, Mining area, metro cities etc.
    • Suitable for Mobile Toilet applications
    • 100% maintenance free, continuous biological process.
    • Complete elimination of pathogens.
    • Economically viable.
    • No dependence on the limited and costly conventional energy sources.
    • Can be installed and made operational in 12 hours only.
    • Inoculums charging is only once during the entire life of Bio Toilet.
    • No need of connectivity to the sewage line, septic tank. No disposal of sludge is required.
    • Routine cleaning chemicals like phenyl, soap, Kerosene etc. do not harm Bio Toilet or the inoculums.
