Therefore, to become more competitive and sustain the current position, innovation through extensive research and development is critical for the Indian cement industry. The Indian cement industry should focus on upgrading paper-based applications for conveyor belts, due to which work is done more efficiently with the use of software. There are technologies that aim to modernize oven lines to meet customer needs. Clinker coolers such as H-cooler and Polytrack have also started to be used. Roto-seal technology has been used by some companies for cement bag packaging which helps reduce dust emission, downtime and product loss. Some companies like Ultra Tech Cement use vehicle-based GPS technology through which any interested party can track the real-time delivery status of their order. By using GPS the company focuses on increasing fleet efficiency and improving sales service to customers. As with Ultratech Cement's corporate website, it uses a fully web-based order management system with real-time visibility of order status.
