EcoRevolution: CAPE IGARASSU's Green Leap with thyssenkrupp nucera



CAPE IGARASSU, under Chlorum Solutions, invests €55 million to transform its chlor-alkali plant in Brazil using thyssenkrupp nucera's BM2.7 tech. The upgrade replaces mercury electrodes with eco-friendly membrane electrolyzers, meeting Minamata Convention standards. thyssenkrupp nucera provides engineering, equipment, and consultancy for the project, emphasizing safety and environmental consciousness. Scheduled for completion by 2025, this shift aligns with Chlorum Solutions' commitment to sustainable chlorine and hypochlorite production.


In a significant environmental stride, CAPE IGARASSU, managed by Chlorum Solutions, is steering a €55 million transformation of its chlor-alkali plant in Igarassu, Brazil. Collaborating with thyssenkrupp nucera, a global leader in high-efficiency electrolysis technologies, the project aims to replace outdated mercury electrodes with the cutting-edge BM2.7 technology, embracing sustainability and safety.

The German technology giant, known for its innovative solutions, extends beyond equipment supply. thyssenkrupp nucera is actively involved in the entire project life cycle, providing comprehensive services including engineering, equipment, and consultancy. This strategic collaboration reinforces thyssenkrupp nucera's position as a preferred technology partner in the Brazilian market.

The conversion, slated for completion by the end of 2025, aligns with the Minamata Convention—a global treaty addressing mercury emissions and releases signed in 2013. The BM2.7 membrane technology, with its modular plant concept, not only ensures compliance with international environmental standards but also promises high energy savings through optimized design and cutting-edge components.

Chlorum Solutions, a key player in chlorine and hypochlorite production for water treatment, is making this substantial investment to modernize its technology, securing a sustainable future for chlorine and its derivatives. Rodrigo Duque, Industrial Director of CAPE IGARASSU, emphasizes the importance of staying abreast of technological advancements to guarantee a continuous and environmentally responsible chlorine supply.

The chlor-alkali plant's total production capacity reaches 125 metric tons of chlorine equivalent per day, with the new membrane plant contributing around 80 tons per day—a significant shift from traditional mercury technology. Dierce Wiques, Engineering Director of Chlorum Solutions, notes the pivotal role of thyssenkrupp nucera's BM2.7 technology in this evolution.

Dr. Gerhard Henssen, Managing Director at thyssenkrupp nucera Italy SRL, expresses satisfaction in Chlorum Solutions' decision, affirming the successful collaboration in Brazil. He underscores thyssenkrupp nucera's commitment to tailoring solutions to meet customer needs, emphasizing safety, and environmental compliance.

This transformative initiative follows Chlorum Solutions' prior collaboration with thyssenkrupp nucera in commissioning two modular chlor-alkali electrolysis plants, producing over 30,000 tons of chlorine annually—a testament to their ongoing commitment to sustainable practices in Brazil.


CAPE IGARASSU's substantial investment in transforming its chlor-alkali plant aligns with global environmental standards, showcasing a commitment to sustainable production. Partnering with thyssenkrupp nucera for cutting-edge BM2.7 technology emphasizes the importance of safety, efficiency, and environmental responsibility in the chlor-alkali industry. The completion of this project by 2025 signifies a significant step toward a greener and more sustainable future for chlorine and its derivatives in Brazil.
