9. Briefly describe the waste management practices adopted in your establishments. Describe the strategy adopted by your
company to reduce usage of hazardous and toxic chemicals in your products and processes and the practices adopted to
manage such wastes
The Company ensures responsible waste management practices involving 100% recycling of plastic waste as per EPR PWM, 100% fly
ash use and safe disposal of waste across locations.
Moreover, the waste generated within the plant gets consumed in our Cement plant as input material and hence producing the
value-added product out of waste. The Company is also working with outside partners to use its waste in other value-added products
such as the paint industry where the initial trials were successful.
