9 led to the implementation of a fully automated system for the storage, handling, and feeding of tyre chips into the calciner. This project stands as a pioneering example of sustainable and responsible industrial practices. TYRE AS FUEL SOURCE The composition of automotive tyres is primarily made up of rubber (45-48%), carbon black (22%), iron (15-25%), textiles (0-5%), and additives for compounding and vulcanization (5-8%), with zinc oxide (1-2%) and sulfur (1%). These components create a chemically consistent material, and it’s important to note that under the Basel Convention, automotive tyres are classified as non-hazardous waste. NCB performed a comprehensive tyre characterization study within their Ballabgarh laboratory. This study included conducting both Ultimate and Proximate analyses of the tyre samples. The detailed results of these analyses are presented in Tables 1 and 2, providing valuable insights into the tyre composition and properties, which are crucial for their effective utilization as a fuel source in the project.
