CHENNAI: Tamil Nadu cement plant unit reduced carbon emissions by 2,250 tonnes per year after successfully meeting a quarter of its fuel needs using waste from municipal businesses and industries local.
Reddiplayam Cement Works, the integrated unit of UltraTech Cement, with the increased use of alternative fuels, is now 16.25 times more plastic. Municipal waste came from 11 local municipal companies, including Ariyalur, Erode, Kumbakonam, Thanjavur, Perambalur and Karur. The unit has also sourced plastic waste from cities such as Chennai and Kozikhode.
This waste is co-processed in the cement kilns of Reddiplayam Cement Works as alternative fuels. Co-processing is a term used for the use of non-recyclable waste such as industrial waste, non-biodegradable plastic and other wastes in cement kilns as an alternative fuel and as a raw material, according to a statement.
Overuse of landfills in surrounding districts had previously led to the open incineration of municipal solid waste. Reddiplayam Cement Works’ alternative fuels initiative has reduced the burden of these landfills and helped reduce air and soil pollution in these districts.
It also co-processes plastic waste from paper industries located in several cities in Tamil Nadu, including Karur, Tiruchirappalli and Coimbatore. Waste Derived Fuel (RDF) from trade organizations also contributes as an alternative fuel for the unit, the statement added.
