STL Beyond Business Banner


CSR at STL is seamlessly interwoven in its business operations. Connectivity, Innovation and Sustainability are not only the predominant criteria for all the company’s businesses, but also the overarching themes to create Shared Value.

The UN’s Sustainable Development Goals and 10 principles of the UN Global Compact Network have a strong influence on how STL plans and implements its CSR and Sustainability initiatives. This approach has not only ensured that STL be a responsible corporate entity in the geographies it operates in, but also enabled it to focus on sustaining its triple bottom line impact through "green-clean-lean" technologies.

STL’s Sustainability vision - “Be responsible leaders in ensuring India’s connected future is inclusive for all” is positioned on four key pillars –

  • Community

    Delivering life changing services and technologies to empower communities.

  • Environment

    Developing system-wide approaches that will reduce STL’s eco-footprint ensuring economic returns in the long run

  • People

    Ensuring that people are healthy, safe, engaged and inspired to drive inclusive, equitable growth

  • Conduct

    Creating ethical and sustainable practices, policies, and business models that will support and align to business growth and the economic development of communities.

These, along with a detailed CSR policy set out the road-map that enables STL to leverage its expertise to ensure holistic development of people and communities.

To ensure transparency in operations, accounting and reporting; quality implementation of each initiative and complete focus; STL has set up STL Foundation (STF), a not-for-profit corporate foundation. All CSR initiatives are implemented through STF. This approach guarantees proper alignment of the projects with STL’s core focus areas as well as identifies and appropriately addresses the needs of communities the company operates in.


Based on STL’s sustainability vision and the four key pillars it is anchored on; the company has selected specific thematic areas for conducting its CSR and Sustainability work. These include –


Our education initiatives aim at transforming learning experiences for students from economically deprived communities. Through Public Private Partnerships which enable the reach and expertise to bring about this transformation; STL has introduced pioneering initiatives in the Ed-tech space.

  • Development

    With a vision to provide quality pre-school education, STL’s ‘Smart NandGhar’ programme aims to redevelop existing government Anganwadis at Silvassa, as well as equip them with a set-up at par with private play schools. These NandGhars would primarily be used by children who hail from the tribal villages surrounding STL's operations in the region.

    The model revolves around making the NandGhar a place these children look forward to coming to daily. Vibrant paintings, aquatic themed activities and black boards for the children to practice on are some of the facilities provided. A television and picture charts have been installed to reinforce storytelling and learning sessions through visuals which enhance a child’s recall ability.

    STL has also partnered with Toycra who would be providing the teachers and children with training on how to use special play kits provided at the NandGhars. These kits will enable children below the age of 5 years develop their cognitive and intellectual skills.

  • STL Ed-Tech Initiatives

    STL’s ed-tech initiatives – Virtual Classrooms & Pragyan have impacted more than 437,000 children in Mumbai and Jaipur. Over the last 6 years the virtual classrooms programme has been implemented in 480 MCGM (Municipal Corporation of Greater Mumbai) schools.

Classrooms in Government schools are connected to a live studio where experts interact with several schools and their students simultaneously. The objective of the project is to benefit these student not only in the short-term, but also impact their aspirations and mind-sets towards higher learning, self-confidence and income-earning opportunities for the future.

    STL believes that technology can change the education landscape of our country. Virtual Classrooms and Pragyan aims to mitigate issues such as unavailability of qualified teachers and the dismal quality of teaching in English at municipal schools.

The company’s health interventions are focused towards preventive and curative healthcare solutions for people in remote rural areas that do not have access to basic health facilities due to geographical or financial limitations. This methodology ensures that STL is able to proactively maintain good health and well-being of the communities where it operates in.

  • Medical Mobile Unit (MMU)

    Realizing the critical need the tribal population in Dadra & Nagar Haveli have for primary health care services, STL initiated the MMU programme in 2006. The MMU is run in partnership with the Indian Red Cross Society and ensures tribals across 24 remote villages in the region receive quality healthcare at their doorsteps.

    The programme has till date provided over 214,000 tribals with free health checkups and medicines. It aims to reinforce healthy living through preventive awareness sessions and monitoring of the difficulties faced by the villagers. This has brought about a noticeable change in the health and general well-being of the villagers.

In alignment with the Government of India’s Skill India Mission, STL believes that empowerment drives progress. Through vocational training; communities - especially women are equipped with skills that enable them to access livelihood opportunities. This in turn has enabled STL to bring about gender equality, create decent work opportunities, economic growth, and thus, alleviation of poverty in several villages.

  • Jeewan Jyoti Women Empowerment Programme (JJWEP)

    JJWEP 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 programme 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 1300 women from more than 100 villages across Bhor, Velhe and Haveli talukas in Pune have been vocationally trained . 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 environment is one of STL’s most important focus areas. Climatic and conservational issues are not just a national, but a global concern. STL has hence used preemptive and innovative solutions to address these issues that plague the communities in regions where it has its operations as well as integrated it into its day-to-day operations.


    The company has its Glass and Optic Fiber manufacturing plants in Aurangabad. In view of the drought conditions in this region, STL adopted a 4R approach to counter the issue – Reduce, Reuse, Recycle, and Replenish. Firstly, STL realigned its own processes to reuse waste water directly and replenish it through rain water harvesting. All of STL's manufacturing facilities in India are Zero Water Discharge facilities. This has enabled the company to reduce its operating costs and water consumption as well as lower its water footprint. Secondly, STL undertook Project Jaldoot, which through community ownership and water literacy has prevented drought conditions in 11 villages. The project replenished over 785,000 cubic meters of water, which is almost 2.65 times the amount of water the company uses at its plant. Innovative construction methods helped create water tables where it was not possible before and also ensure the longevity of the redeveloped structures.
