Environment Management Division (EMD), established in 1989, is the corporate unit certified with ISO 9001 Standard. The unit plays a pivotal role in consolidation of the efforts of the plants, mines and units towards environment protection and resource optimization through its multifarious activities involving
proactive interface between SAIL units and the regulatory agencies,
monitoring and assessment,
awareness campaigns and skill up-gradation.
In addition to these, EMD with constant co-operation from plants, mines and units, is paving its way for propagation of EMS linked to ISO 14001 for various shops and units, including warehouses.
Major Activities of EMD
Within the ambit of notified environmental standards applicable for emission and discharge of pollutants into the environment and rules pertaining to eco-friendly management of various wastes, being generated inside the plant premises as well as in the townships, SAIL plants and mines operate its processes without disturbing the ecological balance. SAIL has also drawn its environmental vision in consonance with the Corporate Environmental Policy, which not only addresses the need to be compliant but also emphasises on striving to go beyond. Besides, SAIL is committed to address the stakeholders’ concerns and communicate its environmental philosophy to all the stake holders.
Since inception, SAIL plants and mines have been putting their relentless efforts in sustained manner, so as to conduct various operations in an environment friendly manner. These have resulted in the reduction of emissions and discharge levels, increase in utilization of solid wastes and greenery development. SAIL plants and mines are efficiently operating the pollution control devices/facilities and maintaining regularly through revamping and refurbishing and also up-grading them as and when required, for the purpose of complying with the applicable environmental standards, which are becoming more and more stringent day by day.
With the concerted efforts, the Particulate Matter (PM) emission load (kg/tcs) is getting declined progressively. Moreover, during the expansion cum modernisation programs, state of the art technologies along with latest pollution control facilities have been installed, as a result of which the pollution level and CO2 emission have also come down.
Similarly, water pollution level at the steel plants and mines is strictly controlled through effective utilisation of the Effluent Treatment Plants (ETPs) installed at the various shops, rejuvenation of the existing local water re-circulation systems and recycling of treated waste water as much as possible. The waste water arising out from different operations at both the plants and mines is treated in the ETPs and is discharged through the outfalls at the boundary, which conforms to the stipulated norms for respective parameters. The specific effluent load in the discharged effluent has reduced appreciably.
The improvement of environmental performance of SAIL during the last five years is given below:
Specific effluent load reduced by around 26%
Specific effluent discharge reduced by around 18%
Specific particulate matter emission load reduced by around 14%
Specific CO2 emission reduced by around 5%
Specific water consumption reduced by more than 1%
Blast Furnace (BF) slag utilisation increased by more than 3%
Adoption of clean technologies and state-of-the-art pollution control equipment/ facilities:
Some of the major best available technologies adopted as steps towards implementation of clean technologies as well as latest pollution control facilities during its massive expansion cum modernization programs are as follows:
Higher capacity (tall) coke oven batteries equipped with Land based Pushing Emission Control System, Coke Dry Cooling Plant etc. at BSP, RSP & ISP.
Sinter Plant equipped with improved ignition system (multi-slit burners), Waste Heat Recovery facility from sinter cooler etc. at RSP & ISP.
Blast Furnace of higher capacity, equipped with Top Pressure Recovery Turbine (TRT), Waste Heat Recovery facility, Pulverised Coal Injection, Cast House De-dusting System, Cast House Slag Granulation Plant and torpedo ladle at BSP, RSP & ISP.
Phasing out of energy-intensive ingot route across SAIL plants.
Walking Beam Reheating Furnace (RHF) in place of pusher type RHF at the Rolling Mill in reducing energy consumption as well as CO2 emission at all the plants.
Waste plastics utilized in road making at RSP:
RSP has recently taken up a green initiative for using waste plastics in the hot mix of road making. As a pilot project, a stretch of one km road has been constructed successfully. More stretches of road at RSP and other plants are being planned to be made with waste plastic.
Project for Bio-sequestration of CO2 at RSP:
For the purpose of reduction of CO2 emission and sequestration of the generated carbon back into the system, SAIL is assessing its carbon footprint in one hand and potential of sequestration of CO2, through its existing biotic resources, on the other. A project on carbon sequestration through afforestation has been taken up at the site of Rourkela Steel Plant. M/s Tropical Forest Research Institute, Jabalpur, has been engaged as the sequestration partner to carry out the project in February, 2014. The project will continue till March 2019.
Water Conservation ~ sustained drive towards a better tomorrow
Over a period of time, SAIL plants and mines have been taking up various initiatives for reduction in water consumption for its operation. However, to conserve this precious resource further, water conservation has now become a priority area both in its works and the townships and the society as a whole. This noble endeavor is being continued on sustained basis beyond the observance of January 2017, as the water conservation month.
A month long awareness programs were carried out all across the plants, mines and units, in order to create awareness amongst the employees, their family members and all the stakeholders regarding the need for water conservation.
Furthermore, to achieve appreciable reduction in water consumption over the last year and also to develop a holistic perspective on water conservation, both short term and long term implementable action plans were formulated at the plant and mines level. The short term action plans have already been implemented, as a result of which water consumption has become come down. The long term action plans are at different stages of implementation. Much needed improvement started showing up.
Over and above, implementation of concept for “Zero Liquid Discharge (ZLD)” has become a mandate to all the plants and mines. To this effect, necessary actions have already been taken up across SAIL plants and units.
Environment friendly disposal facility of Poly Chlorinated Bi-Phenyls (PCBs) at BSP:
Polychlorinated Biphenyls (PCBs), highly toxic environmental pollutants, are the class of synthetic organic chemicals which are used in many industries. These chemicals are categorized as Persistent Organic Pollutants (POPs) under an international agreement on managing Persistent Organic Pollutants (POPs), called Stockholm Convention. The notification on Regulation of Polychlorinated Biphenyls was issued in April, 2016. As per the notification, use of PCBs in any form shall be prohibited completely by 31st December, 2025.
Understanding the country’s need for developing a state-of-the-art facility for management and disposal of PCBs accumulated in the country, BSP in partnership with the MoEFCC and UNIDO has initiated a project for setting-up of an environment-friendly disposal facility at its site. The project has been funded partly by the Global Environment Facility (GEF) through UNIDO. SAIL has committed to co-finance the project by extending infrastructure facilities like provision of land, building, civil works, utilities and manpower etc. The project is likely to be completed during 2018-19.
Implementation of Environment Management System (EMS) linked with ISO-14001:
The Environment Management System had already been implemented at most of the plants and mines and the same is presently under practice. In addition to that, following SAIL units has been certified with EMS in recent years:
Chandrapur Ferro Alloy Plant, Chandrapur
Barsua Iron Ore Mine, Barsua
Alloy Steels Plant, Durgapur
Warehouses of CMO located at Ahmedabad, Hyderabad, Ghaziabad, Faridabad, Vizag, Chennai, Mumbai, Delhi, Durgapur, Dankuni, Bokaro and Bangalore.
During the year, 2017-18, the warehouse located at Kanpur has also been accredited to EMS. The system is presently under implementation at IISCO Steel Plant.
The plants play an important role in balancing the ecosystem and function as a carbon sink. Keeping the enormous contribution of the plants in mind, SAIL has long been adopting extensive afforestation program religiously in its plants and mines since its nascent stage.
Since inception, an aggregate of 201.54 lakh of saplings has been planted. Through a special drive, about 8.27 lakh saplings have been planted in SAIL plants, mines and warehouses during the FY 2017-18.
Sustainable Development Projects:
Restoration and rehabilitation of degraded ecosystem is essential for maintaining and enhancing bio-diversity as well as replenishing the eco-system services. Mined out area and water body of mine voids of Purnapani Limestone Mines and Bolani Ores Mines have been taken up for ecological restoration by SAIL in association with Delhi University.
Efforts for enhancing utilization of wastes like BF and BOF slag through application of 4R’s (Reduction, Reuse, Recycling and Recovery) Policy:
With a view to increase utilization of wastes being generated inside plant boundary, following R&D based initiatives have been undertaken in recent past:
Steam maturing of BOF slag
Dry granulation of BOF slag
Use of BOF slag as rail track ballast
