Environment Initiatives

Sustainability

Environmental degradation and climate change have been identified as one of the foremost challenges of the 21st century by the Global Risk Report of the World Economic Forum. These risks together act as a risk multiplier, worsening other potential risks to businesses, economy and society. We, at TSLP, are collectively stepping up our initiatives towards environmental conservation and climate action for a sustainable future for all. We are optimising our use of natural resources and aligning our processes to embrace a circular economy across every aspect of our operations. We are enhancing energy efficiency, reducing greenhouse gas (GHG) emissions, alongside minimising water intake and pollution. In addition, we are taking appropriate measures to extend the lives of our mines.

At TSLP, we firmly believe that sustainable production is the key to our success and in the long-run, it will majorly impact our business and its ability to create value. Our operations are subject to various central and state environmental laws and regulations.

Reducing energy consumption

Company has provided its attention towards lowering our energy consumption by setting up an Energy Impact Centre under Shikhar – our continuous improvement programme, wherein we categorised the energy reduction initiatives deployed across our manufacturing units into the following:

  • Six variable frequency drive (VFD) of 132 KW-90 KW installed at DRI in Phase-I, resulting in reduction in power consumption in DRI to the tune of 633 Mwh per year
  • Reduction of LDO consumption from 6.35 ltr/ton to 3.3 ltr/ton at SMS (VD-02) by using BF gas for heating purpose
  • Industrial gases
  • Installation of timer in general illumination (224 light Operates with timer) leading to an energy savings of around 26,228 Kwh/Year

Cognizant of the need to bequeath a sustainable, green planet to our future generations, we have narrowed upon the following imperatives:

Reduce pollution

Pursuing energy usage efficiency

Reduction in greenhouse

Minimizing water usage

Conservation of Biodiversity

Increasing proportion of Green Energy

We focus on maximising waste heat recovery to reduce our energy consumption. During the year, we reported

  • Total 311 MU of green power generated from the DRI and Coke oven exit flue gas was generated which corresponds to savings of 373 kT of natural resource (Coal).

Lowering specific CO2 emission intensity

We undertook various initiatives to reduce CO2 emission intensity including:

Decreased fuel rate at MBF
Reduced specific coal consumption at DRI plant Lowered specific coal consumption at Pellet plant
Increased green power generation ratio by 57% of total power generation in FY 2020-21 compared 49% in FY 2019-20
Enhanced coke yield of 65.68 in FY 2020-21 compared to 65.24 in FY 2019-20
Improved air quality measured at 181 AQI at Gamharia in FY 2020-21, compared to 191 AQI in FY 2019-20$

Minimising Fresh Water Consumption

Steel production is significantly dependent on fresh water. ~4.2 MGD (19,000 KLD) of fresh water is drawn from the river Subarnarekha and is supplied after pre-treatment to the plant for use. We are constantly looking for innovative ways of sourcing and managing water consumption to reduce environmental impact and build long-term water security for our operations and community at large.

17% reduction in water consumption

in FY21

Solid waste utilization

We have undertaken the following initiatives in this direction:

  • Installed bagging plant at DRI to ensure regular disposal of DE dust is packed condition
  • Continued long-term agreements with cement industry players for disposal of blast furnace slag
  • The enhanced processing rate of electric arc furnace slag
  • The increased customer base for disposal of solid waste
  • Emphasised on knowledge and resource-based synergy initiatives with Tata Steel

Increasing Green Cover

The company has made an extensive endeavour to increase its green cover across all locations which are all-pervasive. To control pollution in our operational zones of Gamharia, Joda and Vijay-II mines, we are planting trees using the Miyawaki plantation technique near our units. The Miyawaki plantation technique uses native plant species and provides 10x faster growth, resulting in 30 times denser than usual forests.

Other initiatives to reduce emissions

  • Annual maintenance contract (AMC) for O&M of pollution control equipment (PCE) was introduced
    which resulted in system availability of over 90%
  • Overhauling of ESPs and strict operational controls resulted in drop in particulate matter (PM) emission by
    over 17% as compared with previous year at Gamharia plant; to reduce dust levels in workplace environment
    and to improve ambient air quality within the Gamharia plant, capital approval of ₹42.78 crore has recently been accorded, under which, 11 projects are under various stages of implementation
  • Sp. CO2 intensity at Joda had dropped from 1.77 tCO2/ TDRI to 1.75tCO2/tDRI through effective operational control and good maintenance practices
  • There had been substantial reduction in PM and Sox emissions at the sponge iron plant at Joda; drop of
    around 22% in particulate matter emissions compared to previous year was achieved in FY 2021-22 through
    addition of fields in electrostatic precipitator (ESP) of kilns; SOx emissions in stack were also regularly monitored and through prudent use of coal, the level of SOx emissions at Joda also reduced from 1.89Kg/tDRI to 1.47Kg/tDRI
