As natural resources get dangerously depleted, we are consciously making efforts to embed sustainability considerations across all investments, business decisions and operational activities. Our key underlying principle is RRR: Reduce, Reuse and Recycle. This is helping us minimize resource consumption, waste generation and carbon emissions. We are increasingly focusing on developing efficient and sustainable products & processes targeted at reducing carbon footprint, preserve natural resource consumption and fight climate change.
Our constant focus on innovation and making products more efficient for our customers has also helped contribute towards reduction in consumption of resources. One such innovation during the year has been the light-weighting of crankshaft ,reducing weight of the product by 12%. We continue with the practice of replacing wooden boxes with metal pallets and packaging boxes that can be recycled and reused.
Minimizing carbon footprint through the reduction of GHG emission is of paramount importance to us. During the year, we procured 31.18 MW of solar power to reduce energy consumption from fossil sources. In our manufacturing processes, we continue to improve and innovate on ways to reduce consumption and the resultant emission. Some of the key measures undertaken towards this include:
These actions, coupled with other measures, have resulted in a reduction in carbon emissions from production. Emissions declined from 1.41 per ton of production in FY 2020 to 1.28 per ton of production in FY 2021.
We are continually undertaking efforts to reduce hazardous and non-hazardous waste in our production. During the year, we undertook measures like recycling of waste oil through change in disposal pathway which reduces hazardous waste load and recycling of ETP sludge which reduced thereby reducing disposal to landfilling.
Curbing water consumption is one of the fundamental aspects of sustainability. Activities such as upgradation in recycling of treated effluent, recycling of RC fan cooling water using close loop system have led to reduction in freshwater usage. Further, we are also using rainwater harvesting techniques to recharge water table.
We ensure a circular ecosystem whereby 100% raw material scrap is recycled to manufacture clean steel. About 30% waste heat is recovered using regenerative burners resulting in reducing the fuel combustion. We also have zero discharge of wastewater. It is treated and reused for maintenance of greenery in the plant.
