-.,. . rejected. As the solvents fired in kiln are consistent and in controlled manner, there is no hampering of the production and quality of clinker. Before and after usage of solvents there is no change in chemical composition in heavy metals and minor constituents in clinker. 1.05 Present Thermal Substitution & Achivements Presently the liquid wastes are consumed at the rate of around 1000 MT per month. The average CV has been around 3400Kcai/Kg. The consistency in quality is a big question since the receipts are from different pharmaceutical companies with wide range of solvents and products. Hence continuous monitoring (pre testing of liquid wastes) and data collection is of utmost importance for effective usage of these wastes without compromise on safety, operations, and quality of clinker.

The liquid AF have high volatile matter and low flash point (nearly 50deg C). Risk of fire and explosion are foreseen in unloading, storage and feeding systems. A high level of safety measures is called in for trouble and hazard free operation of the system. Nitrogen generators are considered for inertisation of explosive gas mixtures in tank and in the unloading lorry tankers. To ensure safety of the environment, suitable fine protection system was installed by MHIPL. The drives for unloading and fuel transfer pump used in the system are flameproof type. To ensure personnel safety at the unloading area suitable personnel protection equipment is provided. MHIPL got the HAZOP study and pre– commissioning safety audit done through M/S. Cholamandalam MS Risk Services Ltd., for the liquid hazardous waste handling and firing system. Further strengthened the safety system from in house expertise of MHIPL & CRH. 2016-17 1.49 1.6 2.48 3.5 7132 8678 12603 15790 6147 6999 9036 9419 3729 3469 3455 3400 191 180 262 328 Provided "Self-contained breathing apparatus" to meet the emergency within the Alternative Fuel complex. Fire fighting points provided around the complex and two points with Foam injection provided. SOP designed and displayed for interlock provided for unloading pump skid with main storage tank pressure to avoid over pressurisation during tanker's unloading (if main storage tank pressure exceeds 400 mmwc then unloading pump will trip) . 1.07 Hazardous Waste Suppliers to MHIPL & Properties - MYLAN Laboratories Limited - Aurobindo Pharma Limited - Hetero Labs Limited - Dr. Reddy's Laboratories Ltd Pharmaceutical and bulk drug industries emanate waste solvents which consist of high organic content with COD. These waste solvents may be containing Methanol, Toluene, Acetates and other low boiling organic compound which is being used as Alternative Fuel. 21
