Embarking on an eco-centric odyssey, thyssenkrupp Uhde, Ma’aden, and Metso are forging a pioneering alliance for a groundbreaking calcination plant in Saudi Arabia. This plant, strategically positioned at Ma’aden’s Ras al Khair site, symbolizes a paradigm shift in phosphogypsum processing, a by-product stemming from essential phosphoric acid production.

This collaborative venture, supported by the technical prowess of thyssenkrupp Polysius and Metso Outotec, heralds a new era in recycling phosphogypsum while concurrently capturing CO2 emissions. The audacious project aligns seamlessly with Saudi Arabia's Green Initiative and Vision 2030, projecting a reduction in carbon emissions and repurposing phosphogypsum into a valuable, reusable resource.

Hassan Al-Ali, Ma’aden Phosphate's Executive Vice President, expresses anticipation, stating, "This ambitious project will significantly contribute to the Saudi Green Initiative and align with our Kingdom’s Vision 2030."

Lucretia Löscher, COO of thyssenkrupp Uhde, acknowledges the honor of being selected for this innovative endeavor, emphasizing its transformative impact on the phosphate industry. The project stands as a pivotal milestone in thyssenkrupp Uhde's commitment to facilitating the green transformation of its clientele.

Phosphogypsum, laden with challenges due to impurities and limited direct applications, becomes the focal point of this inventive treatment process. The process unfolds a triple benefit. Firstly, it converts phosphogypsum into quicklime (calcium oxide, CaO) through a low-emission calcination process. Utilizing alternative fuels like hydrogen or sulfur, this process minimizes CO2 emissions, championing environmental sustainability. thyssenkrupp Polysius, renowned for its expertise in the cement and lime industry, supplements this with additional know-how.

Secondly, the process facilitates the recovery of sulfuric acid, fostering a closed-loop system. This not only minimizes waste but also optimizes the utilization of resources.

Thirdly, the quicklime generated binds CO2 through carbonization, giving rise to limestone. This versatile end product finds applications in the construction industry or cement production, epitomizing a holistic approach to waste reduction and sustainable material usage.

Conclusion:

The triumvirate of thyssenkrupp Uhde, Ma’aden, and Metso unfolds a chapter in sustainable metallurgy. Their collaborative initiative not only harmonizes with global sustainability objectives but also serves as a testament to the transformative influence of circular economy practices in the phosphate industry. By reshaping waste into valuable resources, the project charts a course toward a greener, more sustainable future.
