  • Jeewan Jyoti Women Empowerment Institute

    The Jeewan Jyoti Women Empowerment Institute was setup in 2014 at Ambavane, Taluka Velhe.

    Although just 50 kms away from Pune, this region was largely underdeveloped and had a patriarchal society. Women thus had no freedom to voice their concerns and thoughts and the literacy rate among them was extremely low. The institute aimed at addressing these issues by not just empowering rural women with equal learning opportunities and professional training courses in areas such as nursing, tailoring, beauty culture and computers among others; but also ensuring their holistic development by making them self-sufficient, feel respected in their families and have a part in the decision making process. Jeewan Jyoti also endeavors to reach out to women of all age groups through various off campus programs on Personality Development, Health and Financial Knowledge.

    Till date, over 700 women have been trained at the institute and 561 have successfully completed the courses offered. Women who have passed out from the institute now earn an additional income of Rs. 2,000 to 12,000 per month. Some of the women have even started their own businesses using the skills learned at the institute becoming entrepreneurs in the true sense.

    The students which include women from across 93 villages; through their renewed confidence and ability to now even support their families have changed the outlook and mindset of the communities they live in. They have become role models for girls and women in the region and ambassadors for the institute. Through them, the institute has ultimately impacted over 28,000 lives. Child marriages in the villages the institute covers have reduced and the marriageable age of women has increased from 15 to 17 years to over 20 years.

    In view of the drought conditions in Aurangabad, STL through its CSR implementing arm - STL Foundation (STF), constructed several dams, mati nala bunds and other water storage structures between 2006 to 2011 in villages worst affected by the drought; and also initiated several process modifications at its Optic Fiber (OF) plant in Waluj to reduce water consumption and achieve zero water discharge..

    For revival of those structures and ensure water sustainability in new villages, STL initiated Project Jaldoot in 2016. The entire project was done through community participation which brought in their ownership and ensured its viability.

    Simultaneously, by ensuring Zero Water Discharge at its OF plant, STL reduced its water consumption by 35% and costs by Rs. 70 lakhs per annum. An Effluent Treatment Plant and Multipurpose Effective Evaporator were installed and a robust monitoring system started to ensure efficiency. Processes where waste water (within permissible limits) could be reused directly were identified and changed.

    Through these efforts STL replenished 644,000 cubic meters of water in the communities surrounding its plants in Aurangabad. This replaced capacity which is almost 2.5 times the amount of water STL uses at its plants has enabled the company to become net water positive.
