The project not only met but exceeded expectations, achieving a thermal substitution rate (TSR) of 23%, surpassing the targeted 21% set by the plant. NCB played a pivotal role in the project, from the initial feasibility study to the plant’s commissioning. The article delves into the project’s methodologies, emphasizing NCB’s role in creating an advanced, fully automated system for efficient tyre chips utilization, exemplifying sustainable and responsible industrial practices. INTRODUCTION This article highlights the success story of NCB in providing consultancy services to establish a fully automated system for storing, handling, and feeding tyre chips into the calciner at a cement plant with a kiln installed capacity of ~5000 clinker per day. The project exceeded expectations by achieving a thermal substitution rate (TSR) of 23%, surpassing the targeted value of 21% set by the plant. NCB played a pivotal role in the project, spanning from the initial feasibility study to the commissioning of the plant. The cement plant made a significant commitment to utilizing tyres as a valuable fuel source in their cement rotary kiln. This strategic decision serves a dual purpose: firstly, it reduces the plant’s reliance on fossil fuels, mitigating concerns related to their availability and cost. Secondly, it addresses the pressing issue of waste disposal, resulting in substantial resource savings that would otherwise have been allocated to waste management. In this article, we will delve into the project’s methodology, led by NCB, which
