Cemvision has developed a revolutionary green cement technology that reduces CO2 emissions by 95% compared to traditional Portland cement production. The Swedish company uses industrial waste materials like steel slag and mine tailings instead of virgin limestone, processing them at lower temperatures with renewable energy sources. Notable achievements include securing a record €10 million seed round in 2024, becoming Fast Company's Top 10 Most Innovative companies, and signing commercial contracts with major players like LKAB, Vattenfall, and JM. The company is backed by Bill Gates' Breakthrough Energy and plans to scale to 5 million tons annual capacity by 2030.
