UltraTech Cement Limited safely co-processes over two lakh tonnes of waste material including 80,000 tonnes of non-recyclable plastic waste as fuel annually. Most of the integrated cement manufacturing units of UltraTech have adopted thermal substitution by co-processing municipal and industrial waste.
As an alternative to fossil fuels, the cement units of UltraTech collect waste from municipal bodies and other industries for co-processing in their kilns. This not only helps the units in reducing the consumption of fossil fuels but also helps in eliminating harmful waste from environment.
Two of UltraTech’s integrated cement manufacturing units Gujarat Cement Works based in Kovaya, Gujarat and Reddipalayam Cement Works based in Ariyular, Tamil Naduare leading the way in co-processing municipal and industrial waste. Hazardous and non-hazardous waste gets burned at extremely high temperatures.
In FY 17-18, Reddipalayam Cement Works has achieved thermal substitution rate of 18.16%. The unit has tied up with 18 different municipalities for procurement of municipal solid waste. Currently, the unit is using 13 different types of alternative material as fuels. The unit has installed extensive shredding systems which has helped them use a variety of materials.
Gujarat Cement Works (GCW) achieved a thermal substitution rate of 8.97% substituting fossil fuels in FY17-18. The unit has established an alternative fuels laboratory with comprehensive analysis. The unit also has mechanised automated extraction and a dedicated feeding system.
