Indian Scientists Invent Eco-Friendly Device to Dispose Sanitary Napkins!

Called GreenDispo, the device has been designed in such that it will incinerate the sanitary napkins completely with minimal flue gas emission.

Two leading Indian scientific institutions have come together with a private partner to launch a new high tech device that ensures that the growing popularity of sanitary napkins become less of an environmental nightmare.

Called GreenDispo, the device has been designed such that it will incinerate sanitary napkins completely, with minimal flue gas emission. It is estimated that 432 million pads are already been disposed of every month in the country and this is expected to grow multifold in the coming years.

Inappropriate handling of used pads is already posing a major challenge as the pads grow harmful pathogens causing serious health and environmental hazards. In addition, blocking of drainage paths due to disposed of napkins is becoming a critical issue.

The new device combines the expertise of the Hyderabad-based International Advanced Research Centre for Powder Metallurgy (ARCI) in the area of processing and shaping of ceramics, the knowledge of Council of Scientific and Industrial Research’s Nagpur-based National Environmental Engineering Research Institute in flue gas emission control, and the skill of Secunderabad-based Sowbal Aerothermics in energy efficient designing and manufacturing.

Launching the product, NEERI Director, Rakesh Kumar, said the specially designed heaters of the device generated a temperature of more than 800 degrees Celsius, which helped in the complete combustion of the used pad. It also had a secondary heating chamber with a temperature of 1050 degrees Celsius to take care of any hazardous emissions from the incinerator.

ARCI Director, Dr G. Padmanabhan, noted that ARCI experts have designed special ceramic holders for the device to ensure that the heat is channelized most effectively. The concentration of heat to the pads not only provide reduced ignition time, higher peak temperature, the increased life expectancy of the heater element and reduced power consumption.

The GreenDispo prototype

Mr. V.V.S.Rao of Sowbal Aerothermics said that the device will be available with a power rating of 800 and 1,000 watts and a unit size of  two to three cubic feet volume. It is a batch type incinerator suitable for use anywhere including rural areas, colleges, schools, hostels, offices and public places. It has been tested for emissions and reliability of performance through field trials under practical conditions. It will be marketed by Messrs Girl Care under the name of `Pad Burn”.
