Designing biogas plants to treat food waste at source
The Green Initiatives team at Infosys designs biogas plants using constant stirred tank reactor technology to treat food waste at source. Food waste constitutes more than 35% of non-hazardous waste across campuses, with the Bangalore Development Center alone serving 17,000+ meals daily.
Infosys treats 100% of its food waste scientifically. Compost and biogas are products from our food waste treatment process. Indigenously developed technology enables 20% energy savings annually and replaces ~ 6,820 LPG cylinders of 19 kg-capacity at our food courts.
Automated biogas plant
Infosys has a biogas plant capacity to treat 3,700 tons of food waste annually, across our campuses in India. Smart feeding and biogas management systems with electronic controls manage feeding of the digester, recirculation of slurry, and flaring of waste gas. Far infrared burners improve the effectiveness of gas usage by ~ 25%, while advanced automation minimizes plant downtime and improves gas output by 20%.
Infosys has installed mechanized shredders and composters to produce organic compost. Organic waste converters treat garden and food waste aerobically. Garden waste is mulched and composted in mulching units and vermicompost pits. The composters treat more than 2,500 tons of food and garden waste annually and produce 750 tons of micro-nutrient-rich organic compost.
