Nuada and MLC have signed a memorandum of understanding (MoU) to collaborate on a project aimed at demonstrating net-zero lime production at MLC’s flagship facility in Ste. Genevieve, Missouri. The initiative will utilize Nuada’s advanced MOF-based VPSA carbon capture system to reduce CO2 emissions by 95%. This project aligns with MLC’s commitment to adopting innovative technologies that reduce greenhouse gas emissions, energy consumption and waste in an industry with inherent CO2 emissions deriving from the calcination of limestone.
Nuada’s carbon capture solution is designed specifically for carbon-intensive industrial processes, where traditional CO2 capture methods are often impractical due to high energy and integration costs. The technology leverages MOFs (Metal-Organic Frameworks), a highly selective advanced solid sorbent that enables efficient CO2 capture with reduced energy use, alongside a vacuum swing pressure adsorption (VPSA) process, which utilizes pressure rather than heat to separate CO2 from flue gases. This innovation tackles both the cost and operational challenges that conventional carbon capture presents, making it an ideal solution for the lime industry, where process emissions are a significant barrier to decarbonisation.
“Our breakthrough in carbon capture technology sets a new standard for energy efficiency, paving the way for transformative decarbonisation in hard-to-abate sectors like lime manufacturing,” said Dr. Jose Casaban, co-CEO of Nuada. “Through this collaboration with MLC, we are driving the next generation of carbon capture forward, setting a new standard for emissions reduction and sustainability in the lime industry.”
With a reputation for high-purity lime products, MLC operates its Ste. Genevieve facility to serve essential sectors, including construction, environmental protection, water treatment, food and agriculture. In alignment with its commitment to sustainable development and environmental protection, MLC will integrate Nuada’s carbon capture solution to strengthen its dedication to process innovation, waste management and emissions reduction. By aligning with the United Nations Sustainable Development Goals, MLC further supports water conservation, pollution control and low-carbon production across its operations, setting an industry standard for sustainability.
“Our collaboration with Nuada reflects MLC’s dedication to exploring advanced technologies that reduce our carbon footprint while maintaining the high standards of purity and quality our customers expect,” said Fiona Woody, Director of Sustainability and ESG at MLC. “The smaller footprint and significantly lower energy consumption of Nuada’s technology make it highly attractive to us.”
Nuada’s and MLC’s combined approach directly supports the decarbonisation goals of the lime industry, aligning with U.S. and international climate targets for net-zero emissions by providing a tailored solution for this hard-to-abate sector.
