SUSTAINABILITY @ Infosys Driven by Values

Clean energy for all 2 India is fourth largest consumer of electricity in the world Over 300 million people in India do not have access to electricity Over USD160 billion was lost in foreign exchange in 2012-13 for oil and coal imports. Infosys consumes 262 million units of electricity annually in India Infosys unit cost of electricity is rising at an average rate of 8% YOY Can we lead the way in addressing the energy problem?

Clean water for all 3 The per capita availability for water has reduced by 2/3 rd in the last 60 years. India stands water stresses and is closed to being categorized as water scarce Infosys Mysore did not get water from municipal sources for an entire month of May13 Infosys Electronics city did not get water for a week in May13 Can we be a part of the solution and set benchmarks?

Solid waste management goals at Infosys Achieve 100% segregation at source. Segregation is the key to waste management. Organic waste: All organic waste generated to be treated in our campuses (nothing should go out) Inorganic waste: All non-hazardous dry waste to given to authorized recyclers/handled to ensure zero disposal to landfills Hazardous waste: All hazardous waste to be handled by authorized vendors only. Zero disposal to landfills All waste that cannot be recycled or is not feasible to recycle should be converted to energy using waste to energy converters 51

Waste to energy converter 52 Granulated, - Plastic waste - Rubber waste - Non-recyclable mixed waste Oil (47%) Petroleum Gas (18%) Char (35%)

Output from converter 53 53

CFL and tube light recycling system Discarded tube lights and CFLs Recovers mercury vapor which is sent to recyclers Contain mercury vapor which is very toxic. Mercury can get into human body through air, water, food chain and adversely affects health Separates glass, plastic and metal components from hazardous material to enable recycling 54 54
