Ma’aden partners with Metso and thyssenkrupp Uhde to develop unique phosphogypsum recycling and CO2 capturing complex in Saudi Arabia


Jan 10, 2024

Ma’aden announced that it will enter into a frame agreement with Metso and thyssenkrupp Uhde for the development and licensing of Ma’aden’s Integrated process concept, aiming for greenfield facilities at Ras Al Khair in Saudi Arabia. The complex will include technology for CO2 capturing with lime produced from the calcination of phosphogypsum using sulfur, leading to a reduction in CO2 emissions across Ma’aden’s phosphate business, making it more sustainable in the long-term.

The complex will enable the deployment of an innovative patented concept, which has been officially recognized by the United States Patent and Trademark Office. The patent will allow Ma’aden to use new technology to reduce carbon emissions and recycle phosphogypsum into a useful resource.

Ma’aden’s patented approach is dual-purpose, not only contributing to global warming mitigation through sustainable carbon dioxide (CO2) capturing but also providing a viable solution for recycling phosphogypsum addressing two of the most pressing environmental challenges facing the phosphate industry – the decarbonization of polluted CO2 and the effective utilization of phosphogypsum, a by-product of phosphate production often left in large quantities.

Hasan Ali, Executive Vice President, Ma’aden Phosphate, said, “This pioneering patent, combined with our new CO2 capturing complex, underscores Ma’aden's commitment to sustainability. We look forward to working with Metso and thyssenkrupp Uhde to develop this important project that will truly change and reduce the carbon footprint of our phosphate business. It puts us at the forefront of innovation, turning what was once leftover material into a valuable resource, while significantly reducing CO2 emissions. It's a giant leap towards a sustainable future.”

Hannes Storch, Vice President for Metals and Chemicals Processing at Metso, commented: “We are excited to see this unique project moving forward. The new concept for the phosphogypsum processing will be a major step forward in the fertilizer industry, contributing to sustainability targets, such as waste recovery and limiting global warming. Metso contributes to the project with our extensive know-how and experience in the field of fluid bed, gas cleaning and sulfuric acid solutions.”

"We are honored to be chosen from our esteemed customer to provide our technology and expertise," stated Lucretia Löscher, COO thyssenkrupp Uhde. "We are providing the innovative process to turn the phosphate industry into a circular economy. This project will be another important milestone for thyssenkrupp Uhde in enabling the green transformation for our customers.”
