UltraTech Cement partners with UCLA on zero carbon lime Technology Pilot

This partnership aims to reduce the carbon footprint of cement production by up to 90%.

The Zero Carbon Lime (ZeroCAL) Technology

The ZeroCAL technology is a novel approach to reducing carbon emissions from cement production.

ZeroCAL technology eliminates CO2 emissions from cement production.

This approach is based on the ZeroCAL technology developed by the University of California, Berkeley.

ZeroCAL: A Revolutionary Approach to Cement Production

The Problem with Traditional Cement Production

Traditional cement production is a significant contributor to greenhouse gas emissions, primarily due to the calcination process that occurs during the production of Ordinary Portland Cement (OPC). This process involves heating limestone to extremely high temperatures, resulting in the release of large amounts of CO2 into the atmosphere. In fact, it’s estimated that cement production accounts for around 8% of global CO2 emissions.

The ZeroCAL Approach

The ZeroCAL approach, developed by the University of California, Berkeley, offers a revolutionary solution to this problem. By utilizing the ZeroCAL technology, cement producers can effectively eliminate CO2 emissions associated with cement production within the established OPC clinker framework. This approach is based on the principle of using a novel calcination process that replaces the traditional high-temperature calcination process.

Key Features of ZeroCAL

Clean Hydrogen and Oxygen Generation: The ZeroCAL technology generates clean hydrogen and oxygen to heat the cement kiln, reducing the need for fossil fuels and minimizing emissions. Low-Temperature Calcination: The novel calcination process used in ZeroCAL operates at lower temperatures, resulting in reduced energy consumption and lower CO2 emissions. Improved Energy Efficiency: The ZeroCAL approach improves energy efficiency by utilizing waste heat from the calcination process to generate additional energy. ### Benefits of ZeroCAL**
