System in the boiler division has been set up as well. This has helped suspended particulatematter in the boiler reduce by 50%. In the dust prone Flax spinning department, we haveintroduced a centralized Dust Extraction System, which has arrested the suspended fine flaxfibres in the air and improved the quality of ambient air.EFFLUENT TREATMENT PLANTS IN ACTIONTo better our environment conservation efforts, at Veraval we have made severalmodifications. To cite a few for instance:• To control suspended solids in the treated effluent, we have segregated the acidiceffluent from the viscose effluent stream.• To check the pH of the effluent as specified by the State Pollution Control Board, we useblack lye (an alkali solution) from the viscose.• Changes in the causticizer, zinc clarifier and the suspended solid clarifier, basically thepollution control equipments, have helped upscale their performance.• The use of steam and process condensate from MSFE for the washing of the sandfilterin the spin bath has proved beneficial.Most of the carbon black processes do not produce any effluents. An oily water treatmentPlant and settling Ponds take care of effluents generated through usage of water forcleaning and domestic purposes. To treat the demineralised Plant effluents, a highlysophisticated Reverse Osmosis Plant has been instituted. This process purifies the effluent.The entire treated water is then recycled into the process, so ultimately there is virtually zerodischarge.Novel measures towards environmental protection have been afoot at Jayashree Textiles.After the expansion of the inprocess house and wool-combing capacities at Rishra, we haveadded a new flocculator, to ensure that the Effluent Treatment Plant capacity is beefed up tomeet with our requirements.To raise the level of our waste-disposal methods, at the Jayashree Textile Plant, wehave installed two grease recovery plants. These enable recover grease from the woolscouring effluent. Grease so obtained is then provided to the pharmaceutical and cosmeticsindustry sectors, who use it as a raw material input.Currently Jayashree Textiles is also engaged in an innovative process modification inthe Effluent Treatment Plant. This process entails treating the wool combing effluent througha dissolved air floatation mechanism, followed by bacterial treatment. In collaboration withthe Jadavpur University, we have successfully installed a Prototype Plant.So also at both the Insulator Plants, all environmental conservation processes are inplace.MEASURING OUR WORKImportantly we have our environment protection systems constantly audited. At Veraval,the Environment audit is effected by the Central salt and Marine Chemical Research Institute,(Bhavnagar), a Gujarat Pollution Control Board recognized Institute. At the Carbon BlackPlants, a surveillance audit by KPMG is carried out every six months. Similarly at our TextilePlant in Rishra, the Bureau of Indian Standards carries out bi-annual audits. Besides this wehave trained environmental systems auditors, who conduct periodic audits. These audits area validation of the high environment management norms adhered to by us.Carbon Black: An environmentally friendly productGREEN AT HEARTHigh temperature manufacturing generates energy, which in turn is As we are green at heart, we have embarked on an ongoing afforestation drive. Moreefficiently used by heat exchangers during the various stages of the than 5400 trees were planted during the year in the Gummudipoondi Plant. Infact at theprocess. The calorific potential of the waste gases is utilized in the Carbon Black Units, every year one thousand trees are rooted in the soil.

They add grace andCarbon is thus produced as an environmentally friendly product. beauty and lend a tranquil ambience. For us, it is “walking the talk.”123 30
