Ambuja Cements, part of the Adani Group, has partnered with UK-based clean technology company Leilac to build one of the world's largest commercial-scale low-carbon cement production facilities at its Sanghi plant in Kutch, Gujarat. The project will test Leilac's carbon capture and hybrid electric heating technology, aiming to cut coal use to zero and capture unavoidable process CO2. If successful, the facility could be scaled up 7 to 8 times to capture over one million tonnes of carbon dioxide annually. The partnership supports Ambuja Cements' SBTi-validated net zero target for 2050 and its broader decarbonisation strategy. The company is also building nearly 1 GW of captive renewable energy capacity to electrify cement manufacturing. Leilac's CEO said the goal is to demonstrate an economic and replicable solution for the global cement industry, which is one of the hardest sectors to decarbonise due to process emissions from limestone calcination. Cement production accounts for roughly 8% of global CO2 emissions, and most of those come from the chemical process itself, not just energy use. This project is notable because it targets those process emissions directly with a technology that can be scaled. If the economics work, it could set a template for other cement plants in India and beyond.
