The series of figures below provide detailed statistics on the multiple categories of waste generation, recycling and disposal pertaining to our operations. Other waste includes broken furniture, tiles, and worn/torn carpets – which is largely recycled.
- Organic Waste Converters (OWC)’s commissioned in all owned locations
- 90% of organic waste is being handled in-house
- Bio-gas currently operational in 3 locations and being evaluated for 3 other locations
- 100% of waste is handled as per approved methods
- Internal audits are done as part of EHS
- Modified Operational Control Procedures (OCP) and e-waste recycler requirements being rolled out in FY2017 Q1
- 116 tons of construction and demolition waste across locations is now segregated and sent to municipal authorized landfills. Alternative options being explored
92.4% of the total waste from our IT India operations is recycled -through both, in-house recycling units and through authorized vendor tie-ups. Details of different categories of solid waste disposal (All figs in metric to unless mentioned specifically)

We noticed an increase in sludge from 1309 to 3666 which is largely due to a technical issue with equipment at one of our site. Major renovations across the campuses contributed to the increase in construction debris which constitute a major part of other scrap.
During FY 15-16, the total end of life E-waste collected and recycled through authorized vendors was 320 tons. We ramped down our hardware manufacturing business and closed operations in March 2014. While we continue to still offer product take back service for our B2B customers, we foresee a continued drop in the quantum of EOL from consumers over the next 3-4 years.
We have started working on the recommendation of e-waste audits conducted earlier for better management of electronic waste. Based on the recommendations, e-waste recycler guidelines and operating procedures have been revised as per the new e-waste guidelines from the government. These now include comprehensive records verification for better material traceability. All recyclers go through an empanelment procedure.
There were no incidents of significant spills of oil or chemicals during inbound transportation in the reporting period.
We ensure adequate maintenance of our DG sets present in 47 of our locations, this helps in minimizing the emissions of air pollutants like oxides of Nitrogen (NOx), oxides of Sulphur (Sox) and particulate matter. A scheduled PPM (Planned Preventive Maintenance) is in place for carrying the maintenance of the DG sets to check the efficiency of the DG sets. Monthly stack monitoring is also carried out to check NOx, SOx and SPM levels to ensure the emissions are within the regulatory norms.
The average of stack emissions of 100 DG’s at 18 of our larger locations is as follows. This is the average of emission quality reporting as of March 31, 2016.
The age of DG’s is a significant factor which can impact emissions. We also have hired DG’s at some locations running for extended periods of time, in some cases for 24X7, due to insufficient supply of grid power. This leads to reduction in efficiency of combustion over extended period of time.
Indoor Air pollutants
Indoor air quality is seen to have a correlation with health of employees and can be a cause of some respiratory ailments. We regularly monitor presence of Indoor air pollutants like VOC (Volatile organic compounds), POP (Persistent organic pollutants) and other hazardous air pollutants. The data across few campuses in March 2015 shows negligible detection of such pollutants. In the next year, we plan to set up comprehensive mechanisms to monitor and audit indoor air quality and report aggregate values of the same across campuses.
Controlled emissions of ozone depleting substances (ODS)
The quantity of refrigerants, including R-22 in 2015-16 was 5.4 metric tons for 34 locations. Out of that, R-22, a ODS substance under Montreal Protocol amounts to 2 tons.
