“Wealth not Waste”
Commissioning of “Nisargruna” new project at IWSA

Indian Women Scientists’ Association (IWSA) is a registered NGO established in 1973 and it has ten branches all over India.  It is a representative body of working women from various disciplines of basic and applied sciences and technology. The Association’s multi-faceted scientific and community - based activities are all geared to develop a scientific temper in the society (www. iwsa.net). IWSA has recently completed its 40 years of effective community service. IWSA also works towards spreading awareness about environment issues. Eco friendly technologies such as rainwater harvesting and solar water heating systems have already been adopted at IWSA’s working women’s hostel at its head quarters at Vashi. 

In our cities, generation of huge amount of untreated biodegradable waste on dumping yards leads to water, air and soil pollution and therefore some measures have to be taken urgently.

IWSA has therefore taken up a new project “Wealth not Waste”. It has two aspects, first to create awareness about the segregation of dry & wet waste material in the society and secondly to install a solid waste treatment demo plant of “Nisargruna” at IWSA campus. Installation of the Nisargruna plant has been graciously funded by The Hemendra Kothari Foundation.

“Nisargruna” biogas technology for treating solid biodegradable waste developed by BARC is well proven with more than 100 plants working all over the country. The Technology involves treatment of biodegradable waste in two successive steps- first step involves aerobic digestion of waste and the second involves anaerobic digestion. The end products are biogas containing methane and weed free manure. The biogas can be used for cooking in the kitchen or generation of electricity. The plant installed at IWSA campus has capacity of treating 50kg waste per day. The biodegradable waste will be collected from IWSA hostel as well as residential complexes, vegetable market and eateries around IWSA. Although the biogas generated shall be used in the IWSA kitchen, the main purpose for installation of the plant is successful demonstration of SWM.

With installation of this plant, IWSA has once again proven its commitment towards protection of environment and efforts to solve societal problems through implementation of technology.
