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.

Diminishing 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:

  • Power consumption and generation
  • By-product gases
  • Industrial gases
  • Fuels and consumables

Under these categories, company has undertaken various initiatives for improving equipment efficiency, optimising equipment loading and run-time, alternate process assessment, reducing leakages, maximising waste heat recovery, reducing auxiliary consumption, evaluating value-in-use for by-product gases, combustion efficiency, alternate fuel, heat-resistant paint and others.

Some of our key energy conservation projects led to:

  • Lowered coke rate in the Blast Furnace (BF at474 kg/tHM in FY 2020-21 compared to 487 kg/tHM in FY 2019-20)
  • Reduced coal consumption at DRI unit by 952 kg/tDRI in FY 2020-21 compared to 994 kg/tDRI in FY 2019-20
  • Cut down specific power consumption at sinter plant by 3%, BF-1 by 5%, Wire Rod Mill (WRM) by 15% and DRI plant by 12%
  • Decreased auxiliary power consumption in SMS Plant
  • Lowered Prime Hard Coking Coal in coke blend » Reduced coal use at pellet plant by 15%
  • Decreased Light Diesel Oil (LDO) consumption in blooming mill, Straight Bar Mill, Vacuum Degassing 02
  • Reduced Low Gross Calorific Value (LGCV) raw coal use, as it was replaced by DRI char – a solid by product of DRI plant

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

Increase In The Use Of Green Energy

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

  • 23% increase in coke oven Waste Heat Recovery Boilers (WHRB)-based power consumption
  • 22 MW (vis-à-vis 16 MW in FY 2019-20) waste heat from our coke oven based WHRB by arresting leakage in duct and steam line, maintenance and cleaning of boiler tube, installing new Boiler Feed Pump (BFP), Quick Closing Non-Return Valve (QC NRV) by changing QC NRV in turbine and reduction in raw steam in de-aerator
  • 8.4% increase in DRI WHRB- based power consumption
  • 20 MW (vis-à-vis 15 MW in FY 2019-20) waste heat power generated from the DRI based WHRB by arresting the flue gas leakage, insulation of steam line, boiler tube cleaning, elbow duct inspection and cleaning to avoid the cleaners formation, maintaining the boiler input temperature and draught

ILowering 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

We undertook various water conservation projects to reduce specific water consumption, including the following:

  • Arrested water leakage of SMS#3 combustion chamber
  • Stopped water loss by providing new cooling arrangement at Mini Blast Furnace (MBF)-1 Diesel Generator (DG) set
  • Laid Effluent Treatment Plant (ETP) treated water line at Pick Casting Machine (PCM) and Slag Granulation Plant (SGP) of MBF-2
  • Restored damaged cooling towers
  • Prevented various leakages and closely monitored individual water inlets by providing flowmeters
  • Reused and recycled 100% wastewater through its ETP
7.53 m3/tcs Specific water consumption

in FY21

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.
