Summary
• The company’s NewYield Technology converts waste streams from pulping operations into functional filler pigments, reducing disposal costs and raw material consumption in the production of precipitated calcium carbonate (PCC). This solution enhances product performance, including improved bulk, opacity, and strength.
• MTI’s FulFill technology portfolio provides high filler solutions, allowing customers to increase filler content in paper by 1-10% and beyond, reducing fiber dependency and offering significant operational savings.
• The company's ENVIROFIL Technology is a recycling solution that enables papermakers to recover mineral pigments from deinking residue by converting these materials into PCC. This innovation replaces quicklime in PCC production, using mineral-rich ash waste from the deinking process of recycled fibers.
• MTI's paper pigments and coatings solutions are designed to enhance product performance and manage costs. Albacar PCC offers a range of grades that provide superior opacity, brightness, and improved sheet strength and bulk. The Albaglos PCC family of coating pigments delivers superior results in paper and board coating, thanks to its prismatic shape and steep particle size distribution.
• Opacarb PCC products are specifically designed to maximize fiber coverage and light scattering, offering high brightness and opacity. These pigments cater to manufacturers seeking to enhance optical coverage while reducing base sheet furnish costs. Lastly, Megafil PCC serves as a prismatic filler for paper and board, offering light scattering and strength-enhancing properties for a high-quality, lustrous finish.
April 18, 2023, Minerals Technologies Inc. (MTI) is expanding its presence in the paper markets of China and India through long-term agreements with major paper companies. These agreements involve building and operating on-site precipitated calcium carbonate (PCC) satellite plants at Andhra Paper Limited in India, Nine Dragons Paper in China, and Zhejiang Zhefeng New Materials Company in China. The plants will collectively produce over 180,000 metric tons of PCC annually. MTI’s patented NewYield® LO PCC technology, enhancing sustainability by repurposing waste from the pulping process, will be introduced in India for the first time at the Rajahmundry plant. Imerys Imerys is a global leader in mineral-based specialties for industrial applications, delivering high-performance mineral solutions to a broad range of industries. Headquartered in France, Imerys operates across 39 countries, with more than 13,700 employees working on five continents. The company’s primary focus is on developing mineral solutions that enhance the performance of their clients’ products, all while embedding sustainable practices into its operations. Imerys is divided into three main business segments: Performance Minerals (PM), Solutions for Refractory, Abrasives and Construction (RAC), and Solutions for Energy Transition (SET). One of Imerys' flagship products is calcium carbonate, which is a versatile mineral used in industries such as paints, plastics, paper, and pharmaceuticals. The company produces both ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC), with a significant presence across Europe, North and South America, and Southeast Asia. Performance Minerals caters to markets like plastics, paints, coatings, ceramics, and filtration, delivering functional additives that enhance product properties. The business is organized into two geographic areas: Europe, the Middle East, Africa, and Asia-Pacific (PM EMEA & APAC) and the Americas (PMA). Solutions for Refractory, Abrasives and Construction focuses on specialty minerals used in extreme conditions such as in the refractory, foundry, and building industries. Solutions for Energy Transition is primarily centered around Imerys Graphite & Carbon (IGC) and its participation in The Quartz Corporation, supporting the energy storage and semiconductor industries. Sustainability is at the core of Imerys’ operations, driven by its SustainAgility program, which aims to create positive value across the value chain. In 2023, the company achieved a 24% reduction in greenhouse gas emissions from its 2021 baseline, a key milestone in its objective to align with the 1.5°C climate trajectory by 2030. The company also maintains high sustainability standards across its supply chain and was recognized in the 93rd percentile by EcoVadis for its environmental efforts. Imerys continues to focus on innovation and sustainability, ensuring that its mineral solutions contribute to a more resource-efficient and environmentally responsible future. November, 12, 2023, Imerys is set to expand the manufacturing capacity of its Marble Hill, GA calcium carbonate plant with a multi-million-dollar investment. The project will include new equipment and automation technology to improve efficiency and address bottlenecks. This expansion aims to better serve the building and construction markets, while also creating jobs in the local community. The plant produces specialty minerals used in flooring, coatings, and other construction applications. Recent Developments• January, 10, 2023, Holcim has acquired Nicem, a leader in grounded calcium carbonate in Northern Italy. This acquisition enhances Holcim’s green formulation capabilities, using Nicem’s low-emission materials to advance sustainable building solutions like ECOPact and ECOPlanet. The move supports Holcim’s "Strategy 2025 – Accelerating Green Growth" by expanding in aggregates and ready-mix concrete.
• May, 18, 2021, Omya International AG has introduced OmyaPET, a new range of functionalized calcium carbonates for PET applications. Initially launching in Europe, the product serves as a cost-effective opacifier for white opaque PET bottles and BOPET films, such as UHT milk bottles, with a lower environmental impact. OmyaPET meets EU 10/2011 food contact standards and is made from 100% recycled materials certified by Bureau Veritas, ensuring production efficiency without compromising quality.
