Committed to conserve

As a leading cement producer in the South Indian market, we are aware of the detrimental effects that cement manufacturing can have on the environment, both while drawing resources and while disposing the waste material. To mitigate the risks emerging from our operations, we have taken several proactive steps and have established a greener and sustainable operating environment for all.

Maintaining our environmental commitments across areas

Raw material

We have deployed of state-of-the-art mining equipment for mineral extraction and development, which is done strictly in accordance to the mining plans and schemes approved by statutory authorities.

We use CBX and Ramco mine management software to blend various categories of low-grade limestone with high-grade limestone to conserve the mineral and ensure zero rejects from the mines. This is further supported by our use of high-grade coal, and pet coke which is used as a fuel for clinker manufacturing.


At SCL, it is our priority to preserve the natural environment and the various ecosystems it supports. While operating our captive limestone mine, we remain mindful of following sustainable mining practices, including controlled blasting to reduce dust and noise and control our emissions. Further, we continue to work passionately to enhance the green spread in and around our quarry sites, manufacturing units, residential colonies and nearby villages by planting native and other floral species. As a result of our efforts, the area around our mines has become a preferred nesting and breeding habitat for migratory and local avifauna.

Our three-pronged strategy for biodiversity management

  1. Before commencing mining, strategically assess biodiversity impacts caused by regional developments
  2. Once the mines are closed, rehabilitate mine sites not just to re-establish vegetation cover but also to develop a self-sustaining ecosystem that interacts positively with the surrounding landscape
  3. During the life of the mine, offset any unavoidable impacts on biodiversity by supporting conservation activities elsewhere in the region


We have a two-fold approach to energy management and conservation:

A. We use diversified sources for energy generation to achieve energy security, minimise carbon footprint and achieve cost efficiency. Over 30% of our overall energy requirement is met from renewable sources and it is our priority to increase the proportion of renewables in our overall energy mix.

B. We achieve better energy savings as part of our efficiency improvement initiatives. Investments in technology and state-of-the-art equipment have helped us continuously improve our energy conservation over the years. For example, our Mattampally plant has a Dry Process Rotary Kiln, which uses one of the most energy-efficient technologies to run our cement making operations. [Read more on our various technology-led energy saving interventions on Technology adoption.


As a cement manufacturer, we generate GHGs, dust and SOx and NOx. It is our constant endeavour to minimise these emissions. We are mindful to not only meet the prevalent emission standards, but to exceed compliance wherever possible. We have installed specific equipment and technology to control our emissions.

Our key interventions to control carbon emissions include:

  • Usage of alternate fuels to reduce dependence on carbon-based energy sources
  • Installation of energy-efficient equipment to control energy intake
  • Green belt development to achieve carbon sequestration
  • Reduction in clinker factor
  • Regular maintenance of vehicles to optimise fuel consumption
  • Opting for bulk transport and rail transport wherever possible to reduce the overall carbon footprint

Thermal substitution rate in FY2020

Our key interventions to control dust, NOx and SOx emissions include:

  • Replacing the conventional bag filter with Polytetrafluoroethylene (PTFE) coated filter bags in identified areas
  • Installing the latest generation Reverse Air Bag House (RABH) for main stack to handle kiln and raw mill (vertical roller mill) gases
  • NOx control pre-heater technology for line-2 kiln
  • De-dusting and prover coverage of cargo to avoid air pollution


We are on an expedited path to achieve water neutrality across all our locations, in line with our integrated water management plan.

100% of our industrial water requirements are met by harvested rainwater.

Our water management policy guides our interventions and we continue to undertake holistic initiatives to conserve and reuse water. Some of them include:

  • Efficient measuring and monitoring system
  • Installation of a softener plant
  • Installation of Sewage Treatment Plant (STP)
  • Using treated water for horticulture
  • Awareness programmes for employees

Waste management

Our highly efficient waste management system effectively manages both hazardous and non-hazardous waste produced by our operations. We also co-process waste from other industries in our cement kilns.

Our interventions to treat different waste categories are summarised below:

Solid waste

The solid waste generated during manufacturing is re-collected by means of RABH, Electrostatic Precipitator (ESP) and blast furnaces, and is then reinjected into the process to achieve resource conservation and reduced waste from plant.

Fly ash

Fly ash generated from CPP is used in PPC manufacturing. Other waste generated from plant maintenance such as used oil and metal scrap are disposed of in a responsible manner, complying with the regulatory guidelines.

At SCL, we strive for ‘Zero Discharge’ across all our operations and we do not discharge any process effluents to any water body. Complying with the new regulations, we are also in the process of installing new/upgrading existing STPs wherever necessary.


During the reporting period, both hazardous and non-hazardous waste were disposed of in a responsible manner and no hazardous waste was directed to landfill.
