42 Utilization of Waste Materials as fuel Following Waste Bio mass as fuel in our boiler for generating power Till date 12320MT Bio waste fired 1. Match Box Waste 2. Eucalyptus Wood Bark 3. Juliflora Thorns 4. Juliflora Chips 5. Pencil wood waste 6. Wood Industry waste 7. Pressmud 42

43 Waste utilization 1) Treated water from ETP is used for cane irrigation and Trees plantation around the factory. 2. Co-Gen boiler Ash is utilized as manure in Cane fields. RO Reject water / Boiler Blow down water is used for boiler Ash quenching in place of raw water. 43

44 Renewable Energy Waste materials from forest is used as fuel to maximize the power generation at Co-Gen. We generated 2.86 million units in the last run. Solar Powered Irrigation pumping system (10 HP) in cane forms are being installed widely in our command area of acers. 44

45 Green House Gas Emission Reduction CO 2 Emission Reduction: 500 no Trees planted inside the plant towards the target of 1000 Nos for the year Reduced the Fuel consumption for the same power production by reducing the Specific steam consumption. ( From 5.49 to 5.34 ) Co-Gen Captive power consumption is reduced from 9.75 % to 8.34%. 45

46 Moving towards digital India Green House Gas Emission Reduction (Paperless office & Diesel Consumption Reduction) By introducing I-Cane software we have created Paperless office for cane management. I-Cane - Plot MAP With Measurement Details 40 % of time spent on traveling by cane staff reduced by this Application usage 46

47 Green House Gas Emission Reduction (Paperless office & Diesel Consumption Reduction) Pest Affected Field Captured by I-Cane Mobile (Paperless Office) 47

48 Green House Gas Emission Reduction (Paperless office & Diesel Consumption Reduction) (Paperless Office) I-Cane-Digital Task Scheduler 48

49 Way forward towards Green House Gas Reduction 1) Zero Ground water drawl 2) Plantation of Trees 1000 Trees / Year 3) Utilizing Renewable Energy (Solar Power for Effluent Treatment Plant, Cane Cultivation Etc) 4) Ensuring Emission test for vehicles entering in to Factory premises 49

50 Best Practices Replicated on Energy front in Green Supply Chain 1. Drip irrigation / Micro irrigation for cane cultivation to preserve water & save pumping Electrical Power 50

51 Best Practices Replicated on Energy front in Green Supply Chain 2. Encouraging Cane cultivation closer to factory to reduce the Cane transport for reducing diesel consumption. 3. By using daily tracker S/W we have identified that 60% of cane staff time is wasted in traveling between Cane field and Office. By Implementation I-Cane Software (Satellite mapping, machine based management system) effectively the necessity of travel to office is drastically reduced to 20% this resulted in significant reduction in Petrol/Diesel for Cane Staff vehicles 51

52 Green Supply chain Recycling and Reuse 1) Sugar process water requirement is met with vapour condensate from cane juice. So, ground water drawl for Sugar Process is Nil. 2) Excess condensate water is cooled in Fan-less cooling Tower and used for Greenery development inside the factory. 52
